In a time series study of suicide rates in Japan from 1978–1997, it was found that the social indicators which predict the suicide rates differ for suicides committed for interpersonal, work-related, and health concerns. While measures of domestic social integration predicted the suicide rate for interpersonal reasons, unemployment, and divorce rates predicted the suicide rate for work-related reasons.

SummaryIn a time series study of the USA from 1933 to 1984, fertility rates were associated with the suicide rates of those aged 15–44. The higher the fertility rate the lower the suicide rate for these age groups, for both whites and non-whites, and for both men and women. The results were seen as supporting Durkheim's theory of suicide.

For 1950–1985 age adjusted suicide rates were associated with marriage, birth, and divorce rates in Canada in the same way as were crude suicide rates.

The time-series regressions for suicide rates by race and sex for those aged 5 to 14 years in the USA from 1933–1980 were predicted by scores on two factors which had high loadings for year and for the marriage rate.

In time-series regressions, remarriage and divorce rates for the USA from 1933–1935 to 1969–1971 predicted suicide rates while first marriage, remarriage, and divorce rates predicted homicide rates.

ABSTRACT CONTEXT AND OBJECTIVE: The World Health Organization recognizes suicide as a public health priority. Increased knowledge of suicide risk factors is needed in order to be able to adopt effective prevention strategies. The aim of this study was to analyze and compare the association between the Gini coefficient (which is used to measure inequality) and suicide death rates over a 14-year period (2000-2013) in Brazil and in the United States (US). The hypothesis put forward was that reduction of income inequality is accompanied by reduction of suicide rates. DESIGN AND SETTING: Descriptive cross-sectional time-series study in Brazil and in the US. METHODS: Population, death and suicide death data were extracted from the DATASUS database in Brazil and from the National Center for Health Statistics in the US. Gini coefficient data were obtained from the World Development Indicators. Time series analysis was performed on Brazilian and American official data regarding the number of deaths caused by suicide between 2000 and 2013 and the Gini coefficients of the two countries. The suicide trends were examined and compared. RESULTS: Brazil and the US present converging Gini coefficients, mainly due to reduction of inequality in Brazil over the last decade. However, suicide rates are not converging as hypothesized, but are in fact rising in both countries. CONCLUSION: The hypothesis that reduction of income inequality is accompanied by reduction of suicide rates was not verified.

A time-series study of homicide and suicide rates by each method in England and Wales from 1950 to 1985 showed that the sociological correlates of these rates depended upon the method used for killing. This raises the possibility that murder and suicide may not be unitary phenomena, but rather that murder and suicide by particular methods are distinct deviant acts and should be studied separately.
