Hall County’s economy is hot and getting hotter. The Gainesville-Hall metro area has racked up more rankings from business publications, being named one of the best metros for business expansion in the country by Site Selection Magazine — the same publication that has ranked Georgia the best state to do business for the past five years. In January, the Milken Institute named the metro the best-performing small metro in the state and No. 3 for small metros in the nation.
