How this income percentile calculator works
- Everyone with income: Total personal income before taxes: wages, self-employment, investments, Social Security, pensions and other sources, for people aged 18 and over with income above $0.
- Full-time workers: Earnings from work before taxes for full-time, year-round workers: usually 35 or more hours a week for 50 or more weeks of the year.
- Data: the US Census Bureau, 2024 American Community Survey 1-year Public Use Microdata Sample, weighted to represent every adult in Illinois.
- Your percentile is interpolated between the published 1st to 99th percentiles of your age group, so it is precise to within about a point. Groups built on few survey responses, mostly young full-time workers in small states, are flagged.
