Still leaving Illinois: An exodus of people and money
“One taxpayer moved out of Illinois every 10 minutes between 1995 and 2009,” according to this Illinois Policy Institute report, and it appears taxes and tax policies are to blame for many of the losses.
Researchers at the Institute examined IRS and other data and found for 15 years, more people have moved out of Illinois than have moved in. Overall, approximately 806,000 people on a net basis left Illinois for all other states -- taking with them a net of more than $26 billion in taxable income. In 2009 alone, Illinois lost a net of 40,000 people to 43 other states. The U.S. Census Bureau places the 2010 Illinois population at 12.8 million.
