Illinois is one of only two states that lost population over the past decade. In the years since the Great Recession, West Virginia’s population has dropped by 34,500. The decline was largely attributed to that state’s struggling economy. Pew Charitable Trusts released a report Wednesday that showed Illinois had seen slow growth until five years ago when the number of people moving out of the state surpassed the number of people moving in and the number babies being born. Since 2008, Illinois’ population has fallen by 6,000.
