    Social class and dental caries in 11-12-year-old South African schoolchildren
    (1989) Cleaton-Jones, P.; Hargreaves, J. A.; Williams, S. D. L.; et al.
    The objective of this study was to examine effects of social class on dental caries in five African populations. Definitions of social class that could be used for the different ethnic groups are outlined. A total of 1 154 children from rural black, urban black, urban Indian, urban coloured and urban white groups were clinically examined and classified into social class by parental occupations. Within group comparisons showed no statistically significant differences in DMFT or DMFS scores by social class. Comparison of the urban white children to a similar group in South Wales showed slightly lower caries in South African children of similar social class. The complexity of the different ethnic groups in South Africa, in respect of social classification, is difficult to assess for comparison with social systems in developed countries. It is recommended that an appropriate social classification be developed for South Africa ’s developed/developing population mixture. Also as we enter the 1990’s sound baseline caries data need to be collected for longitudinal evaluation of changes in the disease pattern

    Variation by Geographic Scale in the Migration-Environment Association: Evidence from Rural South Africa
    (Federal Institute for Population Research, 2017) Hunter, L.M.; Leyk, S.; Maclaurin, G.J.; Nawrotzki, R.; Twine, W.; Erasmus, B.F.N.; Collinson, M.
    Scholarly understanding of human migration’s environmental dimensions has greatly advanced in the past several years, motivated in large part by public and policy dialogue around “climate migrants”. The research presented here advances current demographic scholarship both through its substantive interpretations and conclusions, as well as its methodological approach. We examine temporary rural South African outmigration as related to household-level availability of proximate natural resources. Such “natural capital” is central to livelihoods in the region, both for sustenance and as materials for market-bound products. The results demonstrate that the association between local environmental resource availability and outmigration is, in general, positive: households with higher levels of proximate natural capital are more likely to engage in temporary migration. In this way, the general findings support the “environmental surplus” hypothesis that resource security provides a foundation from which households can invest in migration as a livelihood strategy. Such insight stands in contrast to popular dialogue, which tends to view migration as a last resort undertaken only by the most vulnerable households. As another important insight, our findings demonstrate important spatial variation, complicating attempts to generalize migration-environment findings across spatial scales. In our rural South African study site, the positive association between migration and proximate resources is actually highly localized, varying from strongly positive in some villages to strongly negative in others. We explore the socio-demographic factors underlying this “operational scale sensitivity”. The cross-scale methodologies applied here offer nuance unavailable within more commonly used global regression models, although also introducing complexity that complicates story-telling and inhibits generalizability.

    Social class, parents' education and dental caries in 3- to 5-year-old children
    (1990) Chosack, A.; Cleaton-Jones, P.; Matejka, J.; et al
    The caries prevalence of 1273-, 4- and 5-y-old white children was determined with mirror and probe under natural light at mother and child clinics. The social class of the family, the educational level of the mother and that of the father were determined from a questionnaire filled in by the accompanying adult at the time of examination. Both social class and parent's education had a statistically significant influence on the caries prevalence: those in the lower social classes and with parents without tertiary education had a much higher prevalence of caries
