At. Geronimus et al., Inequality in life expectancy, functional status, and active life expectancy across selected black and white populations in the United States, DEMOGRAPHY, 38(2), 2001, pp. 227-251
We calculated population-level estimates of mortality, functional health, a
nd active life expectancy for black and white adults living in a diverse se
t of 23 local areas in 1990, and nationwide. At age 16, life expectancy and
active life expectancy vary across the local populations by as much as 28
and 25 years respectively. The relationship between population infirmity an
d longevity also varies. Rural residents outlive urban residents, but their
additional years are primarily inactive. Among urban residents, those in m
ore affluent areas outlive those in high-poverty areas. For both whites and
blacks, these gains represent increases in active years. For whites alone
they also reflect reductions in years spent in poor health.
