Students have recently reported receiving notification from the Census Bureau (part of the U.S. Department of Commerce) indicating a response to the American Community Survey is required by law. This is NOT a scam. Every person receiving the survey is required by law to complete it, and to do so accurately. All responses will be kept confidential by the U.S. government. A fine may be imposed for each question purposefully answered inaccurately or if a person declines/refuses to fill out the survey. The Census Bureau uses the responses to produce statistics.
