Mortality in the United States, as summarized by the age-adjusted death rate―a measure that accounts for changes in the age distribution of the population―has declined in an almost uninterrupted manner since 1960. The death rate is now 43 percent lower than in 1960 (declining from 1,339.2 per 100,000 standard population in 1960 to 760.3 in 2007) (1,2). However, not all Americans have benefited equally from this decline. While there is a decline in mortality among all groups, longstanding gaps only recently began to diminish. Much of the recent improvements in death rates and life expectancy for all population groups can be attributed to ongoing reductions in death rates from major causes of death such as heart disease, cancer, chronic lower respiratory diseases, and stroke (1).
