Ensuring Full Participation in the Census Act of 2024

This bill prohibits the U.S. Census Bureau from asking questions about citizenship, nationality, or immigration status on the main decennial census questionnaire (used every 10 years to count the population). It directly affects all households participating in the decennial census by removing these questions from the standard form. The bill specifically exempts the American Community Survey (ACS), which continues to collect such data for statistical purposes. The key mechanism is amending Title 13 of the U.S. Code to add this prohibition, ensuring the main census remains focused solely on population count.
