We examine the effects of education, unemployment, and racial segregation on age-, sex-, and race-specific mortality rates in racially defined Chicago community areas from 1989 to 1991. Community socioeconomic factors account for large observed areal variations in infant and working-age mortality, but especially working-age mortality for the black population. For black men, the mortality consequences of living in economically distressed communities are quite severe. Segregation effects on mortality are more modest and largely operate through neighborhood socioeconomic conditions, although some direct effects of segregation on mortality for blacks are apparent.
