Life expectancy is defined as the average number of years that a person could expect to live if he or she experienced the age-specific mortality rates prevalent in a given country in a particular year. It does not include the effect of any future decline in age-specific mortality rates.

In 1930, life expectancy at birth in the United States was 58 for men and 62 for women. By 2001, the average U.S. life expectancy was 74 for men and 80 for women. In 2018 the average life expectancy was 80 years for males and 84 years for females.

The model projects life expectancy in the United States to rise to 86 by 2075 and to 88 by the end of the century.

In the orange-colored U.S. states, many people live inactive lifestyles; They don’t involve in physical activity regularly enough, Eat carb-laden diets with laughably large portions suffer from poor education or poverty.

In the U.S., black Americans have lower life expectancies than white Americans. For example, white Americans born in 2010 are expected to live until age 78.9, but black Americans only until age 75.1. This 3.8-year gap, however, is the lowest it has been since 1975 at the latest. The most significant difference was 7.1 years in 1993. In opposition, Asian-American women live the longest of all ethnic groups in the U.S. (85.8 years). The life expectancy of Hispanic Americans is 81.2 years.
