Oh, How They'll Grow?

While the 2010 census will yield hard and fast numbers, Tennessee county population growth has already been projected for the next 20 years by the Tennessee Advisory Commission on Intergovernmental Relations in conjunction with the University of Tennessee Center for Business and Economic Research. They're not claiming clairvoyance, cautioning that assumptions and unforeseen factors make these projections most suitable as an aid in local planning efforts, not a definitive statement. By their reckoning of nearby areas, in 20 years Sevier County will have almost doubled in population, Knox County will have added around 20 percent, Blount County about 50 percent more people—and Anderson County will stay almost the same. Here are the projections, in five-year increments:
