Objectives. This study investigated the influence of an aggregate measure o
f the social environment on racial differences in all-cause mortality.
Methods. Data from the National Longitudinal Mortality Study were analyzed.
Results. After adjustment for family income, age-adjusted mortality risk in
creased with increasing minority residential segregation among Blacks aged
25 to 44 years and non-Blacks aged 45 to 64 years. In most age/race/gender
groups, the highest and lowest mortality risks occurred in the highest and
lowest categories of residential segregation, respectively.
Conclusions. These results suggest that minority residential segregation ma
y influence mortality risk and underscore the traditional emphasis on the s
ocial underpinnings of disease and death.
