Estimation of Infant Mortality Rates Categorized by Social Class for an Australian Population

Estimates are derived for infant mortality rates (including neonatal and post neonatal) categorized by father's occupational category. The only random components in the data come from a random sample of births, and these appear in the denominators of the estimates. We derive simultaneous confidence intervals for the estimates for each social class category. The implication for epidemiological research is noted, as is the possibility of other applications.
