The 1977 suicide rates of the 50 states and the District of Columbia were related significantly to their rates of population increase and immigration. These results, which were replicated with data from 1940, 1950, 1960, and 1970, provide additional support for Durkheim's hypothesized relationship between suicide rates and societal integration, since high rates of immigration and population increase are likely to characterize geographical areas with low social integration. As expected, crime rates and divorce rates were related significantly to suicide rates and to these two indices of social integration.

SummaryData from the 1985–86 Japanese census are analysed to explore the determinants of the divorce rates in Japan's forty-seven prefectures, using two theoretical models: (a) the social integration model, which is shown to have a greater utility in predicting Japanese divorce levels than (b), the human capital model. Female emigration patterns play a significant role in affecting the divorce rate. Population increase and net household income are also important predictors of the Japanese divorce rate and urbanization has a great influence in modern Japan. Demographic and aggregate variables such as migration, urbanization, and socioeconomic factors are useful when organized under a social integration model.

Canada's rate of suicide varies from province to province. The classical theory of suicide, which attempts to explain the social suicide rate, stems from Durkheim, who argued that low levels of social integration and regulation are associated with high rates of suicide. The present study explored whether social factors (divorce, marriage, and birth rates) do in fact predict suicide rates over time for each province (period studied: 1950-1990). The results showed a positive association between divorce rates and suicide rates, and a negative association between birth rates and suicide rates. Marriage rates showed no consistent association, an anomaly as compared to research from other nations.

Abstract World capture fisheries are declining while demand for fish is increasing due to population increase and an upward trend in diet preference where fish is preferred over white meat. It is hoped that aquaculture will help meet this deficit. In Kenya, coastal aquaculture remains under-developed even though over 3900 hectares of land have been designated as suitable for aquaculture. This case study is based on a study where Indian shrimp (Penaeus indicus) were cultured for 106 days, in hapas, inside fertilized ponds at Majaoni in Mtwapa creek, Mombasa district, Kenya. The manures used for pond fertilization were chicken, urea and cow dung. No manure was added in the control treatment. Physical, chemical and biological water parameters were taken weekly, fortnightly and monthly, respectively. Growth performance of the shrimp in terms of weight (g) and length (mm) was monitored fortnightly. The mean growth rates ranged between 1.13 and 2.34% day-1 in the control and chicken manure treated ponds, respectively. The highest net yield (NFY Kg ha-1) and annual production (AP Kg ha-1 yr-1) achieved was 18.87 Kg ha-1 and 64 Kg ha-1 yr-1, respectively, in the cow dung-treated ponds. The data collected from this study formed part of the author's MSc thesis in Aquaculture at the University of Nairobi. A major part of the study was funded by Alcoa Foundation's Conservation and Sustainability Fellowship Program which supported the author as a Practitioner Fellow in 2008. Additional support was provided through the Western Indian Ocean Marine Science Association (WIOMSA) small grant programme.

A reformulation of Durkheim's model of social integration and suicide rates was tested using social survey and census data for social area populations in Flint, Michigan. The hypothesis predicts: the more integrated a social-area population, the lower its suicide rate. It is concluded that the concept of social area defines an adequate unit of analysis for testing Durkheim's model, and the empirical data support Durkheim's original formulation.

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.

A negative correlation between societal suicide rates and social integration has been reported, but rarely specifically examined for suicide rates of the elderly although suicide rates of elderly persons are among the highest. The associations of suicide rates of elderly persons and fertility rates for 81 countries were examined using data from the World Health Organisation and United Nations. Fertility rates were considered a proxy measure for social integration. Multiple regression analysis indicated that suicide rates for males and females in the age bands 65–74 years and 75+ years were independently (negative) correlated with fertility rates. Fertility rates, as a measure of social integration, may interact with, modify and mediate the effect of cultural factors on suicide rates of elderly persons.

SummarySocial indices of social integration, such as divorce, were more successful in predicting the suicide rates of the elderly in the provinces of Hungary than they were in predicting the suicide rates of young adults.

A time series analysis of suicide in Northen Ireland and the USA for 1960 to 1984 revealed different correlates. Whereas divorce rates predicted national suicide rates in the USA, birth and marriage rates predicted suicide rates in Northern Ireland.The major sociological theory proposed for understanding variations in national suicide rates was that of Durkheim. Durkheim proposed that two broad social characteristics were in large part responsible for the appearance of suicidal behaviour: social integration, the degree to which the people in a society were interconnected through social relationships, and social regulation, the degree to which the emotions and desires of people in the society were controlled and channeled by the social norms and customs.Durkheim argued that suicide would be common when social integration was very strong (altruistic suicide) or very weak (egoistic suicide) and when social regulation was very strong (fatalistic suicide) or very weak (anomic suicide). Later theorists have argued that Durkheim placed more emphasis than was warranted on very strong social integration and regulation. Johnson argued, for example, that suicide would be more common when social integration and regulation were weak.

Measures of domestic social integration which have been found to account for the time-series suicide rate in Hungary quite well also accounted for the time-series suicide rates of each province and for villages, towns, and cities.
