Infant mortality and economic status in metropolitan Ohio, total and cause-specific: 1979-81 and 1989-91

"This paper presents the results of an ecological analysis of the relationship between infant mortality and economic status in a metropolitan aggregate comprised of six of the larger cities in Ohio covering the years 1979-81 and 1989-91.... Results of the analysis revealed, first of all, that there continues to be a clear and pronounced inverse association between the aggregate economic status of an area and the probability that a newborn infant will not survive the first year of life. There are, however, some noteworthy race-cause differences....Only one cause, Sudden Infant Death Syndrome, stood out as having a generally consistent and very strong inverse relationship with economic status."
