2010 Census Mail Return Rates for Counties
Story and Visualization by Mike Miciag
For the 2010 Census, the overall final national mail return rate was 79.3 percent. But the rate, the most commonly used metric for measuring participation in the Census, varied significantly across the country.
The Census Bureau defines the mail return rate as the percentage of occupied housing units that returned questionnaires in time to avoid follow up from enumerators. It excludes housing units identified as vacant, those with undeliverable addresses or other units deleted from the mailback universe.
Mail response rates are defined as the percentage of all housing units returning questionnaires in time to avoid follow up from enumerators. It is lower than the mail return rate.
