RelevanceTop

Self-rated health is a widely used indicator of health status. It measures a person's perception of his or her overall health, and has been shown to have a strong relationship with objective measures of health status.

In 2013/2014, the age-standardised proportion of people stating that their health was good, very good or excellent was 92.0 percent, as measured by the New Zealand Health Survey. This is higher than previous years (90.1 percent in 2012/2013, 89.9 percent in 2011/2012 and 90.2 percent in 2006/2007).

An estimated 3,268,000 New Zealanders aged 15 years and over rated their health as good, very good or excellent in 2013/2014, an increase of 73,000 from 2012/2013.

Age and sex differencesTop

There were no differences between males and females in terms of their self-rated health, with 92.0 percent of females and 91.9 percent of males in 2013/2014 rating their health as good, very good or excellent. This pattern is reflected across time.

In 2013/2014, those in the younger age groups were more likely to state their health was good, very good or excellent (93.7 percent for those aged 15–34 years) compared with older age groups. However, a high proportion of older people still rated their health as good, very good or excellent (87.4 percent of those aged 75 years and over).

The proportion of those aged 75 years and over who stated their health was good, very good or excellent increased 7.0 percentage points from 2006/2007 to 2013/2014. Other age groups showed more modest improvements or little change.
