Geographic Region: Public Use Microdata Areas (PUMAs)

Public Use Microdata Areas (PUMAs) divide states into geographic areas containing no fewer than 100,000 and no more than 200,000 people. Illinois has 88 PUMAs.

PUMAs allow data users to make statistical analysis and comparisons because these areas have almost identical population numbers. Examples of data on IECAM reported by PUMA include parents’ and mothers’ education levels, health insurance (ages 5 and under), and languages spoken at home (ages 5 and under).
