ROCKFORD, Ill. (WIFR) -- A new study ranks Illinois among the top 15 states where poverty is "worse than you might think."
The study comes from analysis company 24/7 Wall St. It uses Census figures to rank the states by the percentage-point difference between the official poverty rate and supplemental poverty rate.
Supplemental poverty is a measure of poverty that takes geographic variations into account, such as cost of living, expenses such as medical costs and taxes, and anti-poverty subsidies like food stamps and unemployment insurance.
Illinois' poverty rate stands at 10.9%, the 23rd lowest in the country. But the state's supplemental poverty rate is 12.3%, the 22nd highest in the nation.
This marks the 13th largest difference between poverty rates and supplemental poverty rates in the U.S., according to the study.
In Illinois, only 29.5% of households receive Social Security income, the tenth smallest share of any state.
California had the largest rate in supplemental poverty and poverty rates with nearly a 6% difference.
