Indiana’s population is growing at about half the rate it did during the prosperous 1990s, continuing a trend that began during the Great Recession, new U.S. Census figures show. The Associated Press reports the state’s population grew by an estimated 20,285 residents in 2015, for a 0.3 percent increase that boosted its population to an estimated 6.6 million people statewide, according to Census Bureau numbers. Indiana has been adding about half as many new residents as it did during the 1990s, said Indiana University professor Matt Kinghorn, who’s the demographer at the Indiana Business Research Center.
