In Illinois, about 16 percent of the population uses food stamps, officially known as the Supplemental Nutrition Assistance Program (SNAP). Starting this Friday, all 2,031,000 of them will have less money to spend on groceries. A family of three, for example, will lose $29 a month in benefits. Many social service providers expect more families will rely on already strained food banks.

The change could also have a broader economic impact on the state, $220 million fewer dollars will flow into Illinois through the program.
