This paper uses a new standard model of adult mortality to compare the
mortality patterns of Swedes, Japanese, and U.S. whites between 1950
and 1985. It examines changes in the age patterns of mortality and the
cause-of-death structures within the populations, and the relationshi
ps between those two factors. As Japan has reached a level of mortalit
y similar to that in Sweden, the age patterns of mortality in the two
populations have become more similar despite distinct differences in c
auses of death. The United States has a cause-of-death structure simil
ar to that of Sweden, but the age pattern of mortality is very differe
nt. High mortality in the middle age range in the United States result
s in approximately a one-year loss of life expectancy at age 45 in com
parison with Sweden.
