Suicides in 1991–94 linked to a 1991 census record, and the relative risk (95% confidence intervals) of being linked for suicides from the most socioeconomically deprived 50% of small areas compared with the least deprived 50%

Fraction of suicide deaths linked to census record (%)RR of linkage for most compared to least deprived*
Raw numbers are random rounded to the nearest multiple of three as per Statistics New Zealand protocol with a minimum released value of 6. However, all regression analyses use exact counts.
*The relative risk is calculated by a log-link regression of the probability of a suicide being linked, controlling for age. The analyses include 1037 of the total 1197 suicides (86.6%) with a valid value for small area deprivation.
