Socioeconomic indices and suicide rate in Queensland.

Suicides identified from a suicide register were classified according to socioeconomic indices of statistical local areas. Suicide rates were correlated with socioeconomic disadvantage, as measured by the proportion of persons of low income, low education and high unemployment living in an area. Suicide rates were inversely related to the proportion of families on high income, who owned their homes and who had large houses. Suicide rates of older people (55 years and over) were least influenced by these factors. For females, only the most disadvantaged areas had higher suicide rates. In other age and sex groupings, relationships were mostly linear.
