Longevity may refer to especially long-lived members of a population, whereas life expectancy is defined statistically as the average number of years remaining at a given age. For example, a population's life expectancy at birth is the same as the average age at death for all people born in the same year (in the case of cohorts ).
This list of U.S. counties with longest life expectancy includes 51 counties, and county equivalents, out of a grand total of 3,142 counties or county equivalents in the United States. Most of the counties where people live longest are either sparsely populated or well-to-do suburbs of large cities.
Life expectancy may be confused with the average age an adult could expect to live, creating the misunderstanding that an adult's lifespan would be unlikely to exceed their life expectancy at birth. This is not the case, as life expectancy is an average of the lifespans of all individuals, including those who die before adulthood.
Life expectancy in the United States is rising nearly as quickly as it fell at the start of the Covid-19 pandemic as deaths from Covid-19 and drug overdoses drop. After falling 2.4 years between ...
“Specifically, people who want to increase their chances of living a long life should get the daily recommended amounts of vegetables, fruit, whole grains, nuts, polyunsaturated fatty acids and ...
Biodemographic studies have found that even genetically identical laboratory animals kept in constant environment have very different lengths of life, suggesting a crucial role of chance and early-life developmental noise in longevity determination. This leads to new approaches in understanding causes of exceptional human longevity.
The life expectancy in some states has fallen in recent years; for example, Maine's life expectancy in 2010 was 79.1 years, and in 2018 it was 78.7 years. The Washington Post noted in November 2018 that overall life expectancy in the United States was declining although in 2018 life expectancy had a slight increase of 0.1 and bringing it to ...
Cancer can indeed run in families – though that doesn't mean a specific gene is responsible. According to the American Cancer Society , just 5% to 10% of cancers are closely linked to gene ...
