People
Limitations of data: The family data
presented in this report relates to families within households. In
official statistics, a family is defined as two or more people living
in the same household who comprise either a couple, with or without
children, or one parent and their children. The children do not have
partners or children of their own living in the same household. People
who were temporarily away from home on census night are included as
part of the family. There is no data available on parents and children
who live in different households.

Health
H1 Health expectancy
Definition/formulae: The total number of
years a newborn can expect to live without any self-reported functional
limitation requiring the assistance of another person or a complex
assistive device.
Notes:
- The 2001 estimates have been revised following the official
release of the 2000–2002 complete life tables in March 2004.
- Independent life expectancy estimates for 1996 have been
revised slightly, reflecting changes to the smoothing method required
for the 2001 data and the release of the 2000–2002 complete life tables.
- Māori and non-Māori rates are based on estimates for ages
0–85 years because of the small number of Māori aged over 85 years, and
are referred to here as "partial" independent life expectancies.
Limitations of data: The ability to monitor
health expectancy on a regular basis depends on the availability of
information about disability and levels of disability (ie the
post-census disability survey).
This measure of health expectancy (called independent life
expectancy in The Social Report 2003) has inherent
limitations as a population health indicator. An indicator that
included all levels of disability – not just a single dependency
threshold – would provide a more precise measure of health (ie a
health-adjusted life expectancy). The social preferences (disability
weights) needed to construct such an indicator are not available for
New Zealand.
Data source: Ministry of
Health, revised data.
H2 Life expectancy
Definition/formulae: The expected number of
years a person would live if they were subject throughout their lives
to the current age-specific mortality rates.
Note: Ethnic-specific estimates for the period 1980–1982 to
1995–1997 have been adjusted for undercounting in the ethnic mortality
statistics by linking census to mortality records. They were revised
after the official release of the 2000–2002 complete life tables in
March 2004. The figures differ from those published by Statistics New
Zealand for the same period and are not comparable with earlier
estimates.
The analysis associating life expectancy with levels of
deprivation is based on the NZDep2001, a small-area index of
deprivation based on a principal-component analysis of nine
socio-economic variables from the 2001 Census. The index has been
converted to a scale ranging from 1 to 10, where 1 represents the least
deprived 10 percent of small areas, and 10 represents the most deprived
10 percent. The small areas are about the size of a census meshblock
and have populations of approximately 100
people.
Limitations of data: Available annually only
for the total population. Official Māori/non-Māori data is available
five-yearly only, based on a three-year period around census years.

statistics.
H3 Suicide
Definition/formulae: The number of suicide
deaths per 100,000 population, expressed as a three-year moving average
age-standardised rate, for the population aged 5 years and over.
Age-standardised to the World Health Organization standard
population.
Note: The figures for 2004 are provisional
and subject to revision.
Limitations of data: Because suicide is a
relatively rare event in statistical terms, rates of suicide can vary
markedly from year to year. Any interpretation of trends requires an
examination of rates over several years. Deaths by suicide are subject
to a coroner’s inquiry and can only be officially deemed suicide once
an inquest is complete. This means there can be a considerable delay in
the publication of the final statistics.
Data on the rates of suicide for geographical regions and
cities may be of little value for reporting comparisons because of the
low numbers, and hence highly variable suicide rates. For example,
where populations are small, the rate of suicide can be greatly
inflated by one or two deaths.
Data on attempted suicide is available only for those admitted
to hospital as inpatients or day patients for self-inflicted injury.
Those cared for in hospital but not admitted and those cared for by
primary or community care services are not reported. Therefore, the
actual rate of attempted suicide is likely to be much higher than that
reported in official statistics.
Comparability over time is affected by a change in the
population concept in 1991 (from de facto to resident). Because of a
change in the ethnicity classification in 1995, comparable data is
available only from 1996 onwards. Ethnic-specific mortality data is
also subject to some uncertainty due to the differences in collection
across different providers.
A comparison of international trends in suicide is problematic
due to the different methods used to classify suicide. The New
Zealand age-standardised rate in the international comparison data
has been calculated in a manner consistent with the international
figures available, and may differ slightly from the rates presented
elsewhere (Ministry of Health, 2006a, p 15).

ages); Beautrais (2000) Restricting Access to Means of Suicide in New
Zealand: A Report Prepared for the Ministry of Health on Methods of
Suicide in New Zealand. World Health Organization (2004).
H4 Cigarette smoking
Definition/formulae: The proportion of the
population aged 15 years and over who ever smoke any ready-made
cigarettes or roll-your-own tobacco cigarettes. Up until 2005,
information on smoking prevalence was collected from quarterly surveys
conducted by ACNielsen Ltd and reported by the Ministry of Health. The
historic rates are all crude rates. In 2006 the data came from the New
Zealand Tobacco Use Survey (NZTUS) which was run for the first
time in the first quarter of 2006.
Ethnic rates are age-standardised using the WHO world
population.
Limitations of data: The international
comparison is affected by differences in the collection and
classification of the data. The classification of ethnicity information
changed from 1997 onwards. Therefore, ethnic-specific data before and
after 1997 may not be comparable.
The 2003 data was collected from people aged 18 years and over and
adjusted for the expected proportion of smokers 15–24 years of age.

Estimated resident population, mean year ended December.
H5 Obesity
Definition/formulae: Obesity is defined as
the accumulation of excess body fat to the extent that health is
adversely affected (WHO 2000). It is measured using a Body Mass Index
(BMI) which is calculated by dividing weight (in kilograms) by height
(in metres) squared. Adults with a BMI greater than 30 kg/m2 are
classified as obese. In the 1997 National Nutrition Survey and in the
2002/2003 New Zealand Health Survey, the cut-off for Māori and
Pacific peoples was set slightly higher, at 32 kg/m2. For children, the
measure is the proportion of 5–14 year olds whose BMI (weight/height2)
meets the international definition of obesity established by Cole et al
(2000). The definition adapts the widely used cut-off point for adults
(30kg/m2) to produce age- and sex-specific cut-offs for children and
youth aged 2–18 years.
Information on obesity is based on the 2002/2003 New
Zealand Health Survey, the 1997 National Nutrition survey, the
2002 National Children’s Nutrition Survey, the 1989/1990 Life in New
Zealand (LINZ) Study, and the 1977 National Diet Survey. Although
there was some variation in survey design and response rates, as well
as in height and weight measurement methods, these surveys are
considered to be reasonably comparable.
Limitations of data: The cut-off level is
arbitrary and does not necessarily correspond to levels of health risk.
There is some debate about whether a separate cut-off for Māori and
Pacific peoples is warranted. The 1989/1990 data for Māori should be
viewed with caution as the number of Māori in the survey was small.

Knowledge and Skills
K1 Participation in early childhood education
Definition/formulae: The number of children
aged 3 and 4 years enrolled in early childhood education (ECE)
programmes as a proportion of the estimated population aged 3 and 4
years. ECE programmes include: licensed ECE services (kindergartens,
playcentres, education and care services, home-based services, casual
education and care (no regular roll), correspondence school and te
köhanga reo); licence-exempt ECE services (early childhood development
funded playgroups, Pacific peoples early childhood groups, and
playcentres); and licence-exempt köhanga reo.
Limitations of data: Rates of participation
are only "apparent" because children may be enrolled in more than one
ECE centre. The rates therefore may be inflated. The measure does not
provide information on the length of participation or on the quality of
the programmes, both of which are relevant to positive educational
outcomes. The methodology used for dealing with licence-exempt ECE
groups that did not provide data has changed for 2006. As a result,
enrolment figures for 2006 are not directly comparable with 2005 for
licence-exempt ECE groups.
Data sources: Ministry of
Education, Early Childhood Education, Licensed
Services and Licence-Exempt Groups 2006, Ministry of Education, Prior
participation in early childhood education: new entrants, Ministry
of Education (various years) Education Statistics of New Zealand,
Education Statistics News Sheet, v 10, no 1, March 2001; unpublished
tables.
K2 School leavers with higher qualifications
Definition/formulae: The proportion of
secondary school leavers who left school with a qualification at
National Certificate of Educational Achievement (NCEA) Level 2 or
above.
In Figure K2.1, the data up to 2002 includes school leavers
with:
- National Certificate Level 4
- A or B Bursary/National Certificate Level 3
- Entrance Qualification/42 or more credits National
Certificate Level 3 or above/Accelerated Christian Education
Certificate or overseas award at Year 13 Level
- Higher School Certificate/14–41 credits National
Certificate Level 3 or above
- National Certificate Level 2/1–13 credits National
Certificate Level 3 or above.
The data for 2003 also includes leavers who attained NCEA
Level 2.
The data for 2005 and 2006 includes qualifications at NCEA
Level 2 or above.
Limitations of data: School leaver data
collection was changed as a result of the introduction of NCEA in 2002.
A direct comparison cannot be made between rates up to and including
2002 with rates for 2003 on, due to the change in the qualification
structure. Previous qualifications, such as School Certificate, were
awarded to students if they had completed the assessment and met
attendance requirements, independent of the grade awarded. The new
qualification structure is designed to award students credits when they
have met achievement rather than participation criteria.

Leaver statistics, Ministry of Education (2006) School leavers with
NCEA Level 2 or above; unpublished data from the Ministry of Education.
K3 Participation in tertiary education
Definition/formulae: Participation in
tertiary education is calculated by the number of students aged 15
years and over enrolled with a tertiary education provider (see below)
at any time during the year in formal qualifications (or programmes of
study) of greater than 0.03 Equivalent Full-time Tertiary Study (EFTS).
The data excludes all non-formal learning, on-the-job industry training
and private training establishments that did not receive tuition
subsidies or were not approved for student loans and allowances.
Domestic students only are included.
Modern Apprenticeship students who are studying courses that
fit into the above definition are included in the statistics
(typically, doing block courses at a polytechnic). If their learning is
totally on the job, they will not be included.
Community education courses are excluded from the statistics.
Public tertiary education institutions include: universities,
polytechnics, colleges of education, and wānanga. Private tertiary
education consists of: private providers receiving a tuition subsidy,
private providers with qualifications approved for loans and
allowances, private providers receiving a Ministry of Education grant,
and other private providers registered with the New
Zealand Qualifications Authority.
Limitations of data: The data in this report
relates to students enrolled at any time during the year (from 1994).
In previous social reports, it related to students enrolled at 31 July
in each year. Therefore, the data in this indicator is not comparable
with that in previous social reports.
Changes in the number of institutions, the status of
institutions, and the types of courses offered affect comparisons over
time.

K4 Educational attainment of the adult population
Definition/formulae: The proportion of
adults aged 25–64 years with an educational attainment of at least
upper secondary school level, defined in the International Standard
Classification of Education (ISCED 1997) as Level 3 and above, and
including tertiary qualifications at bachelor’s degree and above (Level
5A/6).
ISCED 3 includes: local polytechnic certificate or diploma,
trade certificate or advanced trade certificate, University Bursary,
Scholarship, Higher School Certificate, Sixth Form Certificate,
University Entrance in one or more subjects, School Certificate in one
or more subjects, other school qualification.
ISCED 4 includes: technician’s certificate, New
Zealand certificate or diploma, and other specified tertiary (the
latter was previously included in 5B).
ISCED 5B includes: university certificate or diploma,
teacher’s certificate or diploma, nursing certificate or diploma.
ISCED 5A/6 includes: post-graduate degree, certificate or
diploma, bachelor’s degree.
Limitations of data: The data for this
indicator is different from that shown in previous social reports
because it refers to December years (previously it was for June years).
This change was made to align the indicator with other indicators based
on data from the Household Labour Force Survey.
Statistical weights used to rate sample data up to population
estimates are updated every five years following each population
census. This requires a revision of historical data. The latest
revision was in June 2004.
Statistics New Zealand has recently recoded "other
specified tertiary" from Level 5B to Level 4. This change should not
have affected the data in this indicator.
The international comparison of the adult population with "at
least upper secondary education" should be viewed with caution. There
are substantial differences in the typical duration of ISCED 3
programmes between countries, ranging from two to five years of
secondary schooling. The Tertiary Level A (bachelor’s degree and above)
comparison is more robust.

Zealand, Household Labour Force Survey, unpublished tables. OECD

A and advanced research programmes), downloaded from the internet 24
April 2007.
Paid Work
PW1 Unemployment
Definition/formulae: The proportion of the
labour force (aged 15 years and over) that is unemployed. The labour
force is the sum of those defined as employed and those defined as
unemployed. Hence the unemployment rate is defined as
unemployed/(employed and unemployed). The unemployed are defined in the
Household Labour Force Survey as those who are without a paid job (or
unpaid work in a relative’s business) and who have actively sought work
in the four weeks before the survey and who are available to take work.
"Actively seeking" includes any actions such as contacting an employer,
asking friends and relatives and contacting an employment agency or
Work and Income but excludes those who have only checked newspaper
advertisements.
Standardised unemployment rates used for international
comparison are seasonally-adjusted rates.
Limitations of data: Data is based on a
sample survey and is therefore subject to sampling error. The
definition of the unemployed excludes some people who regard themselves
as unemployed, including the "discouraged unemployed" – those not
meeting the "actively seeking work" criterion. This group is classified
in the "not in the labour force" category. The unemployment rate also
excludes those who have part-time employment but who are seeking to
work more hours.
Data sources: Statistics New
Zealand (2007d) Household Labour Force Survey. OECD Frequently
Requested Statistics, Standardised Unemployment Rate, downloaded from www.oecd.org on 9 May 2007; OECD
(2006b) OECD Employment Outlook, 2006, Statistical Annex, Table G p 267.
PW2 Employment
Definition/formulae: The proportion of the
population aged 15–64 years employed for at least one hour per week.
The employed are those who worked for pay or profit for one hour or
more in the week before the survey or who worked unpaid in a relative’s
business or who have a job but did not work that week because of leave,
sickness or industrial disputes. The definition used here relates to
the population aged 15–64 years, rather than to those aged 15 years and
over; otherwise results are skewed by differences in the proportions of
the sub-populations over 65 years, particularly when comparing males
with females and comparing different ethnic groups.
Limitations of data: As above, data is
subject to sampling error. The definition of employment includes those
working one hour or more per week, so this will include some people who
are likely to regard their status as closer to unemployment than to
employment. For example, people on the unemployment benefit and
searching for work but working a few hours a week will be counted as
employed.
Data sources: Statistics New
Zealand (2007d) Household Labour Force Survey. The Household
Labour Force Survey figures were rebased using the latest census
information in the June 2004 quarter. The data for all quarters was
revised and there may be some differences between the numbers in this
report and those published in earlier editions. OECD (2006b) OECD
Employment Outlook, 2006, Statistical Annex, Table B pp 248–250.
PW3 Median hourly earnings
Definition/formulae: Median hourly earnings
for employees earning income from wage and salary jobs as measured by
the New Zealand Income Survey, an annual supplement to the
Household Labour Force Survey.
Limitations of data: The final data set
consists of approximately 28,000 valid person records including 4,000
imputed person records. Hourly earnings relate to the number of hours
usually worked and the usual income rather than to the number of hours
actually worked and the actual income. Proxy interviewing may be used
to collect data on income under certain circumstances. Estimates from
sample surveys are subject to error.
Data sources: Statistics New
Zealand (2006g) New Zealand Income Survey, Hot Off the Press,
June 1997 to June 2003 (revised), June 2004 to June 2006 Table 10, and
unpublished data derived by the Ministry of Social Development.
PW4 Workplace injury claims
Definition/formulae: The number of
work-related accident claims reported to the ACC per 1,000 full-time
equivalent employees (one part-time employee = 0.5 full-time employee).
Full-time equivalent employee data is as estimated by
Statistics New Zealand's Household Labour Force Survey.
Limitations of data: The data does not
include workplace accidents where no claim was made to the ACC. In some
cases, there are also delays from when the accident happened to when
the claim is reported to the ACC. For example, there were 240,500
injuries reported for the 2003 calendar year by March 2004, and 246,600
by March 2005, an increase of 3 percent.
Information on workplace injuries for 2005 is based on a new
set of indicators developed by Statistics New Zealand. Comparable
figures are available for 2001–2004 but information from these years is
not directly comparable with previous figures on workplace injuries.
The data for 2002–2004 was revised by Statistics New Zealand in
2006.
Data source: Statistics New
Zealand (2006a) Injury Statistics – Claims for Work-Related
Injuries (2005), Information Release.
PW5 Satisfaction with work-life balance
Definition/formulae: The proportion of
employed people who are "satisfied" or "very satisfied" with their
work-life balance according to the Quality of Life Survey 2006.
Limitations of data: Subjective measures of
wellbeing reflect people’s perceptions of their own situation, which
may differ from their objective status. The survey had a low response
rate (22 percent) which means care should be taken in interpreting the
data.
Note: Ethnicity is based on multiple
responses and is sourced from unpublished tables produced by the
Ministry of Social Development.
Data source: Quality of Life
Survey 2006. The survey was commissioned by 12 of New Zealand's cities
and districts, in partnership with the Ministry of Social Development,
to monitor trends in wellbeing. The total (national) sample size in the
2006 survey was 7,720, which has a maximum margin of error of +/- 1.1
percent at the 95 percent confidence interval. Interviews were
conducted to meet gender, ethnicity, age and ward/region quotas to
ensure the sample was representative of the New Zealand population
as a whole.
Economic Standard of Living
EC1 Market income per person
Definition/formulae: Real Gross National
Disposable Income (RGNDI) measures the real purchasing power of the net
income of New Zealand residents from both domestic and overseas
sources, after taking account of income resulting from international
transfers. GNDI is Gross National Income (GNI), previously called Gross
National Product (GNP), plus net international transfers. Real Gross
Domestic Product (GDP) per person (as used in the OECD comparisons) is
real income produced inside the New Zealand national boundary,
excluding the international transfers included in GNDI.
Derivation of RGNDI: In the published
tables, RGNDI is calculated as follows: constant price gross domestic
product (production-based measure) plus constant price trading
gain/loss plus constant price total net income and transfers. Constant
price trading gain/loss is defined as current price exports divided by
the imports implicit price index less constant price exports. Constant
price total net income and transfers equals investment income credits
less investment income debits plus transfers credits less transfers
debits, all divided by the imports implicit price index.
Limitations of data: Major limitations to
the use of RGNDI as an indicator of wellbeing include its failure to
include non-marketed (and, therefore, non-priced) activities (barring
the exception of imputed rentals on owner-occupied dwellings). RGNDI
provides no information on income distribution. Finally, evidence
suggests monetary measures have a very weak cross-sectional and a
limited time series correlation with self-assessed measures of
wellbeing.
Note: The use of real GDP for OECD
comparisons may over-state New Zealand's relative position because of
New Zealand's growing and high per capita net external debt.

EC2 Income inequality
Definition/formulae: The ratio of the 80th
percentile of equivalised disposable household income to the 20th
percentile of equivalised disposable household income. This indicator
takes into account household size and composition. For international
comparisons, we have compared Gini co-efficients.
Adjustment for family size was made by means of a per capita
equivalisation process based on the 1988 Revised Jensen Equivalence
Scale.
Limitations of data: International
comparisons have been made with data from years around 2000.

EC3 Population with low incomes
Definition/formulae: The income measure used
is equivalised disposable household income after deducting housing
costs. Equivalised disposable household income is the total income from
all sources for all individuals in the household, after deducting tax,
and adjusting for household size and composition.
The adjustment for household size and composition is based on
the 1988 Revised Jensen Equivalence Scale.
Housing costs is the sum of annualised accommodation
expenditure (includes mortgage payments (principal and interest),
payments to local authorities, property rent, rent of a private
dwelling, boarding house, and student accommodation not paid with
formal fees). In this indicator the Accommodation Supplement is counted
as income.
Individuals are ranked by their household’s equivalised
disposable income (after deducting housing costs).
The two low-income thresholds used are of the "fixed line"
type, set at 50 percent and 60 percent of the 1998 median household
disposable income, less 25 percent to allow for average housing costs.
The two thresholds are held constant in real terms by an adjustment
using the CPI. (See Perry (2007) for further detail – especially
Appendices 4 and 5.)
Individuals are grouped according to selected individual,
family or household characteristics for the different analyses. For
this indicator, family means one or two parent families with dependent
children, whether living in a separate household or with others in a
wider household.
The ethnicity of individuals aged 15 years and over is as
reported by the individual. Children under 15 years are attributed with
the ethnicity of the survey respondent.
The methodology used to calculate the figures used in the
international comparison section follows that used by the OECD: the
income concept is equivalised household disposable income; the
equivalence scale is the square root scale (ie equivalence scale
elasticity = 0.5); equivalent household income is attributed to all
individuals in the household; individuals are ranked by their
attributed equivalent disposable income to get the median for that
year; the threshold is set at 50 percent of this (contemporary) median,
a "moving line" approach. There is no adjustment for housing costs.
Limitations of data: The equivalised
disposable income measure (whether before or after deducting housing
costs) is taken as an indicator of a household’s access to economic
resources or of its potential living standards, all else being equal.
The measure is an imperfect indicator of actual living standards, which
are influenced by factors other than current income and housing cost.
People with the same current income level can have different standards
of living as a result of their different net assets, the extent to
which they receive assistance from others, and the extent to which they
have atypical expenditure commitments (eg unusually high medical costs,
debt repayments, transport costs and electricity costs). People who
experience a lengthy period of very low income are likely to have
different life outcomes to those who experience only a transient
episode.
Note: The measures have been constructed
using the household as the income-sharing unit, in line with
international best practice. Previous social reports used the "economic
family unit" as the income-sharing unit. The figures used in The Social
Report 2007, therefore, differ a little from those in previous
editions, although trends over time remain unchanged.

EC4 Housing affordability
Definition/formulae: The proportion of
households and the proportion of people within households with housing
cost outgoings-to-income ratio greater than 30 percent.
Household incomes have been equivalised using the 1988 Revised
Jensen Equivalence Scale.
Housing costs are the sum of annualised accommodation
expenditure (includes mortgage payments (principal and interest),
payments to local authorities, property rent, rent of a private
dwelling, boarding house and student accommodation not paid with formal
fees). In this indicator the Accommodation Supplement is counted as
income.
Limitations of data: Measures of housing
affordability do not shed light on the issues of housing quality,
suitability or sustainability; nor do they explain why affordability
problems may exist, or the extent to which inadequate housing is
occupied to avoid affordability problems. Furthermore,
marginally-housed families are often hidden from official statistics
and are not counted among those with an affordability problem.
Household ethnicity is defined in this indicator by the presence of an
adult of a particular ethnic group. The figures for households defined
in this way are not mutually exclusive.
Data source: Derived from the
Statistics New Zealand Household Economic Survey by the Ministry
of Social Development.
EC5 Household crowding
Definition/formulae: The Canadian National Occupancy standard
sets the bedroom requirements of a household according to the following
compositional criteria:
- There should be no more than two people per bedroom
- Parents or couples share a bedroom
- Children under 5 years, either of the same or of the
opposite sex, may reasonably share a bedroom
- Children under 18 years of the same sex may reasonably
share a bedroom
- A child aged 5–17 years should not share a bedroom with one
under 5 of the opposite sex
- Single adults 18 years and over and any unpaired children
require a separate bedroom.
Limitations of data: There is no
contemporary official statistic or index of household crowding in New
Zealand. There are many frameworks or models used in many countries for
analysing the incidence of crowding. It is unlikely any single measure
of crowding could adequately summarise such a complex and multi-faceted
issue as crowding.
There is no definitive evidence crowding leads to negative
social outcomes, but there are associations between living in crowded
circumstances and negative outcomes. The mechanisms by which these
outcomes result are not clear.
The Canadian Crowding Index is not an objective index of
crowding. The extent to which household members will perceive
themselves as living in crowded circumstances is dependent on many
factors including social and cultural expectations. Furthermore, it
cannot be assumed households requiring one or more additional bedrooms
(based on the Canadian index) will suffer negative social outcomes.
The Canadian Crowding Index is used here as it is both
sensitive to household size and composition. The measure sets a bedroom
requirement for households based on precise criteria.

Civil and Political Rights
CP1 Voter turnout
Definition/formulae: The total number of
votes cast is divided by the estimated number of people who would have
been eligible to vote (voting-age population) on election day, and
expressed as a percentage. To be eligible to vote, a person must be at
least 18 years old and meet residential and certain other criteria.
Limitations of data: The voting-age
population is based on population estimates that are subject to
revision. The 1984 figure is based on the estimated de facto population
aged 18 years and over, as at 30 June 1984.

CP3 Perceived discrimination
Definition/formulae: The proportion of
people aged 18 years and over who perceived selected groups as being
the targets of discrimination (ie subject to "some discrimination" or
"a great deal of discrimination").
Limitations of data: Surveys on perceived
discrimination do not measure actual levels of discrimination against
groups.
The margin of error for a 50 percent figure at the 95 percent
confidence level is 3.6 percent.
Data source: Human Rights
Commission Omnibus Results (Feb 2006).
CP4 Perceived corruption
Definition/formulae: The degree of corruption
perceived to exist among New Zealand politicians and public
officials according to surveys of business people, academics and risk
analysts is used by Transparency International to construct the
Corruption Perceptions Index. Corruption is defined as the "abuse of
public office for private gain". Scores range from 0 (highly corrupt)
to 10 (highly clean).
Due to a small change in methodology, the index no longer
reflects a three-year rolling average of pooled survey results, but now
uses only two years of data. The reason for this change was to improve
topicality; it may enable individual country assessments to reflect
recent developments without lowering measurement precision.
The Corruption Perceptions Index 2006 was based on data from
2005 and 2006 drawn from 12 different polls and surveys from nine
independent institutions. The New Zealand data was drawn from
seven surveys and the overall score of 9.6 was within a confidence
range of 9.4–9.6.
Limitations of data: The Corruption
Perceptions Index score is a subjective measure; there is no hard
empirical data on levels of corruption that can be used for
cross-country comparison. The index was not designed to provide
comparisons over time, since each year the surveys included in the
index vary. The index is a relative measure: New Zealand's ranking
depends not only on perceptions of corruption in New Zealand but
also on perceptions of corruption in the other countries surveyed. If
comparisons with earlier years are made, they should be based on a
country’s score, not its rank.

Cultural Identity
CI1 Local content programming on New Zealand television
Definition/formulae: The hours of local
content broadcast on TV One, TV2, TV3 (to 2004), Prime Television,
Māori Television (from 2005) and C4 (from 2006) in prime time,
expressed as a percentage of the total prime-time schedule. New
Zealand content programming includes first runs and repeats across
all six channels.
Limitations of data: The number of local
content hours broadcast on other free-to-air or pay channels is not
included in the data presented here. Up until 2002, the hours data in
Table CI1.1 was measured over 24 hours; from 2003 onwards it was
measured over 18 hours (6am to midnight).
Data sources: NZ On Air (2007)

CI2 Māori language speakers
Definition/formulae: Māori language speakers
as a proportion of the Māori ethnic group. Māori language speakers are
defined as those able to hold a conversation about everyday things in
Māori.
Limitations of data: The data relies on
self-assessment rather than measuring the actual level of fluency in
the population. The census data comes from a single question about
conversational language ability. More detailed information on the level
of fluency among Māori language speakers is available from two
nationwide surveys done in 2001 and 2006. This data is not directly
comparable with the census data because of differences in the samples
and methodology. For example, the Māori language surveys used
face-to-face interviews, asked a range of questions about language
skill, and asked respondents to place themselves on a five-category
proficiency scale.

CI3 Language retention
Definition/formulae: The proportion of
people who can speak the "first language" (excluding English) of their
ethnic group, for ethnic groups (other than Māori) with an established
resident population in New Zealand, as recorded in the 2001 Census. The
ability to speak a language is defined as being able to hold an
everyday conversation in that language. First language refers to an
indigenous language associated with a given ethnicity rather than the
first language of an individual.
Several criteria were used to identify ethnic groups with an
established resident population in New Zealand. These included total
population size, years since the group’s arrival in New
Zealand and the age distribution and birthplace (overseas and
within New Zealand) of group members. These variables provide a measure
of the influence of time and of the demographic characteristics of the
groups. Each variable was applied independently to a large list of
ethnic groups from which 15 were selected under the broad categories of
Pacific peoples, Asian and European. To be selected, a group needed to
have: a New Zealand resident population of over 2,000 people; a
broad age distribution to investigate the impact of age on language
retention; and sufficient numbers born in New Zealand to make
meaningful comparisons with overseas-born residents.
Limitations of data: While a direct link can
usually be made between a language and an ethnic group, this is not
always the case. Some ethnicities are associated with several languages
and one language can span several ethnicities. While English is an
official language of some groups selected in these tables, the 2001
Census does not distinguish between different varieties of the English
language. English has therefore been excluded as a first language
within these tables. Because the census variables for both ethnic group
and language spoken allow more than one response, there may be some
individuals who appear in more than one ethnic group category.

Zealand (2004a) Concerning Language.
Leisure and Recreation
L1 Satisfaction with leisure time
Definition/formulae: The proportion of people
aged 15 years and over who are "satisfied" or "very satisfied" with
their leisure time, according to the Quality of Life Survey 2006.
Limitations of data: For more information see
PW5 Satisfaction with work-life balance.
Data source: Quality of Life
Survey 2006. For more information see PW5 Satisfaction with work-life
balance.
L2 Participation in sport and active leisure
Definition/formulae: The proportion of adults
aged 15 years and over who were sufficiently physically active, as
defined by the Sport and Recreation Continuous Monitoring Survey. Being
sufficiently physically active means they took part in at least 2.5
hours of physical activity and did five or more sessions (half an hour
or more) in the seven days before being interviewed. Highly active
means doing some vigorous physical activity during the week in addition
to the requirements for being rated as sufficiently physically active.
While based on the validated face-to-face administered New
Zealand Physical Activity Questionnaire (Short Form NZPAQ-SF), the
Continuous Monitor is a telephone administered survey of New Zealanders
aged 15 years and over.
Limitations of data: The Continuous Monitor
administers the NZPAQ-SF by telephone and is self reported. Self-report
methods typically result in overestimated levels of activity.
Furthermore, telephone administered surveys appear to overestimate
overall activity levels more than other survey types (eg face-to-face
surveys). However, irrespective of the method used, differences
reported between groups (eg sex, age and ethnicity) are the same.
Data source: Sport and
Recreation New Zealand (May 2007) Overcoming Obstacles to Action

L3 Participation in cultural and arts activities
Definition/formulae: The proportion of the
population aged 15 years and over who experienced a cultural activity
as measured in the 2002 Cultural Experiences Survey. Respondents were
asked to report on activities they experienced over either a 12-month
period (for goods and services accessed or experienced relatively
infrequently) or a four-week recall period (for activities experienced
on a more regular basis). The survey was undertaken as a supplement to
the 2002 March-quarter Household Labour Force Survey.
Limitations of data: This was an ad hoc
survey, and is not comparable with the indicator in The Social
Report 2001. The focus of this survey was on
experience/consumption; it did not include participation such as acting
or performing.
Data source: Statistics New
Zealand (2002a) 2002 Cultural Experiences Survey.
Physical Environment
EN1 Air quality
Definition/formulae: The level of ambient
concentrations of PM10 averaged annually are reported for
five major urban centres in New Zealand. These levels are compared with
the government’s PM10 guideline value of 20µg/m3 (20
micrograms per cubic metre) averaged annually. PM10 is
particulate matter that is less than 10 microns in diameter.
Limitations of data: Data is reported only at
specific sites in the five major cities and does not always represent
the pollution levels that will be experienced over an entire town or
city. The data, being so location-specific, cannot be compared with an
OECD median. In September 2005, new air quality standards based on
daily average PM10 concentrations were introduced. Regional
and unitary authorities have declared 69 "airsheds" where air quality
may, or is known to, exceed the standards for PM10 or may
require management in the future. When sufficient data is available, we
will report against these standards also.
Any data used in this report that may be subject to volatile
loss has been adjusted by a regionally-determined factor, where
available.
Data source: Collated by the
Ministry for the Environment from regional council publications.
EN2 Drinking water quality
Definition/formulae: The 2000 Drinking Water
Standards for New Zealand (DWSNZ) requires that all water leaving
the treatment plant must be free of both faecal coliform bacteria
(including E. coli) and Cryptosporidium. Additionally,
adequate monitoring and the use of a registered laboratory are required
to demonstrate full compliance with this standard. The indicator is the
proportion of the total population whose water supply complies with the
2000 DWSNZ for E. coli and Cryptosporidium.
Limitations of data: Drinking water rated
not fully compliant may be the result of failing one of the two
microbiological criteria, of failing to adequately demonstrate
compliance by using a non-registered laboratory, or of no or inadequate
monitoring.
Data source: Water Information
New Zealand Database March 2007.
Safety
SS1 Intentional injury child mortality
Definition/formulae: The number of people who
have died as the result of assault or intentional injury, per 100,000
population.
The data was drawn from the following International
Classification of Diseases codes: ICD-9, E960–E969 (up to 1999);
ICD-10, X85–Y09 (from 2000).
Limitations of data: Because of the changes
in the classification of ethnicity in death-registration data since
September 1995, ethnicity data for 1996 and later years is not
comparable with data from before 1996.
Data sources: New
Zealand Health Information Service, Deaths from Homicide and
injury purposely inflicted by other persons (Assault mortality data in
ICD-10), 1948–2003 and provisional data for 2004. UNICEF (2003) A
League Table of Child Maltreatment Deaths in Rich Nations, Innocenti
Report Card, No 5 Table 1(a) p 4. OECD (2005) OECD Health Data 2005,
StatLink to Data for Chart 1.19, p 29.
SS2 Criminal victimisation
Definition/formulae: The proportion of the
population aged 15 years and over who had been victims of one or more
incidents of criminal offending in 2005 as measured by the New
Zealand Crime and Safety Survey 2006 (NZCASS). The survey covers
people in private households. It does not cover commercial
victimisation, "victimless" crimes (such as drug or alcohol abuse), or
crimes against people less than 15 years old.
Limitations of data: Changes in survey design
limit the comparisons that can be made between NZCASS and the two
earlier surveys, the 1996 and 2001 New Zealand National Survey of
Crime Victims.
The overall response rate in the 2006 NZCASS was 59 percent in
the main sample and 56 percent in the Māori booster sample. The
respective figures in the 2001 survey were 65 percent and 57 percent
and in the 1996 survey, 56 percent and 66 percent. In the authors’
view, it is difficult to say how the small drop in the response rate in
the 2006 NZCASS has affected risk estimates (Mayhew and Reilly, p 23).
Victimisation surveys are subject to a number of
methodological limitations such as selective recounting and differences
between groups in willingness to report offences, particularly offences
of a sexual or domestic nature where the offender is known. There are
also limitations in asking people to remember victimisation incidents
and to locate them accurately in time.
A victimisation survey will give a higher count of crime
because it counts unreported crime. A third of all NZCASS offences
became known to the police. Offences regarded as serious were more
likely to be reported, but there was a wide variation between offence
types, with 84 percent of vehicle thefts being reported compared with 9
percent of sexual offences (Mayhew and Reilly, p 35).
Data source: Mayhew, P and
Reilly, J (2007) New Zealand Crime and Safety Survey 2006: Key
Findings.
SS3 Perceptions of safety
Definition/formulae: The proportion of people
who reported that fear of crime had a moderate or high impact on their
quality of life (scoring its effect at 4 or higher on a scale from
0–10, where 0 is no effect and 10 is total effect), as measured by the
New Zealand Crime and Safety Survey 2006 (NZCASS).
The data comes from the survey question "How much is your own quality
of life affected by fear of crime, on a scale from 0 to 10, where 0 is
no effect and 10 is total effect on your quality of life?" The overall
response rate in the 2006 NZCASS was 59 percent in the main sample and
56 percent in the Māori booster sample.
Limitations of data: The question elicits a
subjective assessment of the extent to which fear of crime affects
respondents’ quality of life, which is also subjectively defined. While
the question demonstrates an ability to differentiate between groups,
it is not a reliable measure of the actual status of respondents. Also,
although the results reflect people’s perceptions of their own
situation in a general and ongoing way, they may be influenced by
significant events and subject to fluctuation over time.
Data source: Mayhew, P and
Reilly, J (forthcoming) New Zealand Crime and Safety Survey 2006:
Community Safety.
SS4 Road casualties
Definition/formulae: Number of deaths caused
by motor vehicles per 100,000 population. Number of persons injured as
a result of motor vehicle crashes as reported to the police, per
100,000 population. Pedestrians or cyclists killed or injured by motor
vehicles are included.
The data was drawn from the following International
Classification of Diseases codes: ICD-9, 810–819 (1996–1999); ICD-10,
V01–V89 (2000).
Limitations of data: The collection of
ethnicity data changed during 1995 for both mortality and
hospitalisation data. For mortality data, the basis of ethnicity has
changed from a biological concept to a concept of self-identification;
in mid-1995 hospitalisation data recorded multiple ethnic groups,
whereas previously only one ethnic group could be recorded.
Consequently, a comparison of 1996 ethnic-specific data with previous
years is misleading: 1996 is the start of a new time series for
ethnic-specific data.
Because of a revision of the International Classification of
Diseases, rates for 2000 are not comparable with rates for 1996–1999.
Data sources: Ministry of
Transport; Land Transport New Zealand; New Zealand Health
Information Service; New Zealand Travel Surveys; Statistics New
Zealand; International Road Traffic and Accident Database (OECD),
Issued September 2005. Road casualty data comes from two main sources:
injury data from the traffic crash reports completed by police officers
who attend the fatal and injury crashes; and mortality and
hospitalisation data from the New Zealand Health Information
Service (NZHIS). Ethnic-specific rates of death or hospitalisation are
only available from NZHIS. The New Zealand Travel Survey 1997/1998
was based on a sample of approximately 14,000 people and the survey
report compared results from a similar survey conducted in 1989/1990.
Social Connectedness
SC1 Telephone and internet access in the home
Definition/formulae: The proportion of the
population with telephone and internet access in the home, as measured
by the 2000 and 2004 New Zealand Living Standards Surveys.
The 2000 survey was in two parts: one of 3,060 people aged 65
years and over and the other of 3,682 working-age adults (18–64 years).
Both surveys involved face-to-face interviews with nationwide
representative samples. The 2004 survey was a nationally representative
sample of 4,989 respondents answering on behalf of their economic
family.
Family ethnicity is defined in this indicator by the presence
of an adult of a particular ethnic group. The figures for families
defined in this way are not mutually exclusive.
Note: The data in the international
comparison section of this indicator differs from that included in The
Social Report 2006 due to a revision of the data.

SC2 Regular contact with family/friends
Definition/formulae: The proportion of the
population who had family or friends over for a meal at least once a
month, as measured by the 2000 and 2004 New Zealand Living
Standards Surveys.
The 2000 survey was in two parts: one of 3,060 people aged 65
years and over and the other of 3,682 working-age adults (18–64 years).

Definition/formulae: The percentage of
secondary school students who reported in 2001 that most weeks they got
enough time to spend with Mum and/or Dad (or someone who acts as Mum
and/or Dad).
