Here we grow.
Tennessee’s population increased by 8.9% over the past decade — exceeding the 7.4% national rate — giving the state an estimated population of 6.9 million residents in 2020, according to data released Thursday by the U.S. Census.
The statewide population is up from 6.3 million reported in 2010.
Tennessee’s growth was driven in large part due to Middle Tennessee, which is sizzling.
Nashville-Davidson County saw a 14.2% population boost, adding about 89,200 people through the decade.
Its suburbs saw a bigger percentage boost, with Williamson County increasing by 35.2%, or 64,500 people, and Rutherford County jumping up 30%, or about 78,900 people. Several other Middle Tennessee counties saw population increases that exceeded 20%.
Warren County did not experience such noteworthy growth. Warren County had a population of 39,839 in 2010, according to the U.S. Census, and our population edged up to 40,953 in 2020. That’s an increase of 1,114 residents.
That’s about the same level of growth as some counties that border Warren County.
DeKalb County and Cannon County experienced about the same level of growth, around 1,000 residents.
However, Coffee County and Cumberland County attracted far more residents over the past decade. Those counties saw their populations increase by about 5,000 residents over the past decade.
In a rarity, Grundy County saw its population decrease over the past decade by about 170 residents.
County population figures are crucial in determining how state and federal dollars are distributed. They also determine how state and federal seats are drawn for elections.
In heavily red Tennessee, this isn’t a major concern except for Nashville, which remains a Democratic stronghold. State lawmakers, who are a super majority of Republicans, will no doubt look at ways for Nashville to be divided in hopes Republicans can hold that area too.
