Where You Live Affects How Long You Live
How long we live depends partly on where we live. The average life expectancy in the United States today is about 79 years, but it varies across and within states. (1)
In Tennessee, average life expectancy is about 76 years but ranges from 64 in parts of Washington County to 88 in parts of Rutherford County. There’s also variation within counties and even cities and towns. Within Davidson County, for example, life expectancy ranges from about 66 years to 87. In Shelby County, the range is about 65 to 83, and in Knox County, 67 to 82. (2)
Location matters because our neighborhoods can affect our access to factors that influence health, such as education, health care, jobs, social support, transportation, and healthy foods. Research shows that people who live in wealthy, highly educated communities are more likely to be in better health and live longer than those who do not.
