Have urban/rural inequalities in suicide in New Zealand grown during the period 1980–2001?

Previous studies have noted that in many countries there has been a disproportionate increase in suicide in rural areas, contributing to greater urban/rural inequalities in health. This paper evaluates whether this trend was also apparent in New Zealand during the 1980s and 1990s, a period of rapid social and economic change. Using suicide incidence data for the period 1980–2001, we investigate whether urban/rural status had an effect upon rates of suicide independently of socioeconomic deprivation. While both male and female suicide rates were significantly higher in urban than rural areas in 1980–1982, by the end of the 1990s, urban/rural differences in suicide rates were not significant. The narrowing of urban/rural differences was, to some extent, a result of the growth in suicide rates in more isolated rural communities and small rural service centres. Recent geographical variations in suicide in New Zealand are therefore to a large extent similar to trends observed elsewhere, but are less marked. Potential explanations are offered for the fluctuating urban/rural inequalities in suicide including compositional arguments, rural restructuring and economic decline, social isolation and health service utilisation.
