Hall County’s population grew about 4.5 percent from 2010 to July 2013, according to estimates released today by the U.S. Census Bureau. The county’s population jumped 8,061 over the last three years to 187,745. And the average growth rate of 1.5 percent per year is reflective of the post-recession economic climate that has seen demand for services and new development slow as the area, the state and the nation continue their long road to recovery.
