This paper evaluates the quality of vital statistics and census data f
or estimating African-American mortality over a period of six decades.
The authors employ intercensal cohort comparisons and extinct generat
ion estimates to demonstrate that conventionally constructed African-A
merican death rates may be seriously flawed as early as age 50. Using
the crude death rate at ages 50 + for 1978-1982 in conjunction with es
timated growth rates and two model life table systems, the authors est
imate black age-specific death rates in 1978-1982. These results sugge
st that if a racial crossover in death rates occurs, the age pattern o
f mortality among African-Americans must be far outside the range obse
rved in populations with more accurate data.
