Indicator Report - Life Expectancy at Birth by County, 2010-2012

Why Is This Important?

Life Expectancy is often used to gauge the overall health of a community. Shifts in life expectancy are often used to describe trends in mortality. Being able to predict how populations will age has enormous implications for the planning and provision of services and supports. Small increases in life expectancy translate into large increases in the population.

As the life expectancy of a population lengthens, the number of people living with chronic illnesses tends to increase because chronic illnesses are more common among older persons.

Data Notes

The life expectancy algorithm is modeled after Chiang (Chiang CL (1984) Life Table and Mortality Analysis, Malabar (FL), Robert E. Krieger Publishing Co.). More detailed life expectancy estimates for other age groups and by race can be found on the State Center for Health Statistics website:  U.S. data are for 2010.

Other Views
