Statement on 2020 Census Internet Response Security Precautions

Release Number CB20-RTQ.11 (Revised)

March 20 – If anyone responding to the 2020 Census online experiences a session that terminates unexpectedly, we suggest using a different internet browser. To protect the integrity of the 2020 Census, the Census Bureau is using industry leading artificial intelligence services to protect responses. We are continuously monitoring and refining these security measures in order to enable all legitimate responses while maintaining security.

The U.S. Census Bureau has recently updated text that offers a message to anyone who was blocked: "For security reasons, this session has been terminated. Every response is important. Please try again using a different browser or device."

Anyone can respond online, over the phone, or by mailing in the paper questionnaire.
