Growing Disparities in Life Expectancy

Life expectancy has been increasing in the United States
in recent decades, resulting in welcome gains for individ-
uals but higher costs for federal programs.1 Improve-
ments in life expectancy at birth have occurred for both
men and women and across races. Life expectancy at
birth for men born in 2004 was 75.2 years, almost 10
years longer than men born in 1950. Life expectancy for
women born in 2004 was 80.4 years, more than 9 years
greater than for women born in 1950.2
1. Life expectancy is the number of additional years an individual is
expected to live at a given age. In this issue brief, life expectancy
refers to period life expectancy, which is calculated using current
death rates. Period life expectancies are generally lower than
cohort life expectancies (which are calculated using projected
death rates for a given cohort) because death rates generally fall
over time.

Life expectancy at birth for blacks has risen since 1950
but remains noticeably lower than that for whites.3 Life
expectancy for black men has grown about as much as
that for white men, but that means the six-year gap
between them has been maintained (see Figure 1). By
contrast, black women have experienced disproportion-
ately large gains in life expectancy at birth over the 1950-
2004 period. As a result, life expectancy has risen more
for black women than for white women, halving the gap
between them but still leaving a difference of more than
