Why We Ask Questions About...
Year Built and Year Moved In

Your privacy concerns

We use your confidential survey answers to create statistics like those in the results below and in the full tables that contain all the data—no one is able to figure out your survey answers from the statistics we produce. The Census Bureau is legally bound to strict confidentiality requirements. Individual records are not shared with anyone, including federal agencies and law enforcement entities. By law, the Census Bureau cannot share respondents' answers with anyone—not the IRS, not the FBI, not the CIA, and not with any other government agency.

Questions as they appear on the form

We ask two questions about when a housing unit was built, and when a person moved into that home to produce statistics about housing availability.

Results from these questions

We compile the results from these questions to provide communities with important statistics about housing availability. You can see some of these published statistics here for the nation, states, and your community.
