The United States Census Bureau estimates that the population of Tennessee was 6,651,194 on July 1, 2016, an increase of 304,896 people since the 2010 United States Census, or 4.8%. This includes a natural increase since the last census of 110,000 people (that is 502,451 births minus 392,451 deaths), and an increase from net migration of 191,384 people into the state. Immigration from outside the United States resulted in a net increase of 55,613 people, and migration within the country produced a net increase of 135,771 people.
Twenty percent of Tennesseans were born outside the South in 2008, compared to a figure of 13.5% in 1990. In recent years, Tennessee has received an influx of people relocating from California, Florida, and several northern states for the low cost of living, and the booming healthcare and automobile industries. Metropolitan Nashville is one of the fastest-growing areas in the country due in part to these factors.
The center of population of Tennessee is located in Rutherford County, in the city of Murfreesboro.
