Abstract
This paper presents the results of an ecological analysis of the relationship between infant mortality and economic status in metropolitan Ohio at four points in time centering on the censuses of 1960, 1970, 1980 and 1990. The basic unit of analysis is the census tract of mother's usual residence, with economic status being determined by the percentage of low income families living in each tract. For each period, the census tracts were aggregated into broad income groups and three-year average infant mortality rates were computed for each area, by age, sex, race and exogenous-endogenous causes of death. The most important conclusion to be drawn from the data is that in spite of some very remarkable declines in infant mortality for all socioeconomic groups since 1960, there continues to be a very clear and pronounced inverse association between income status and infant mortality. Indeed, there is some evidence to suggest that it is stronger in 1990 than it was three decades earlier. The general inverse association is observed for both sexes, for whites and nonwhites, and for all major causes of death. At the same time, the data reveal notable variations in the pattern of the relationship over time, as well as several differences between whites and nonwhites in the nature and magnitude of the relationship. Some macro-economic hypotheses are offered to explain these temporal and racial differences in the pattern of the relationship between economic status and infant mortality.
