CENSUS BUREAU: ILLINOIS MAY HAVE BEEN UNDERCOUNTED IN 2020 CENSUS
The Census Bureau released new survey data Thursday suggesting the population of Illinois may have been undercounted by nearly 2 percent in the 2020 headcount. That was one of the findings of the Census Bureau’s Post-Enumeration Survey, or PES, something the bureau does after each decennial census to assess the quality of the census data. The results do not change the official population numbers of any state, nor do they affect congressional reapportionment, but they do help guide the bureau in its planning for the next decennial census.
