U.S. Census Bureau Genealogy
Verified working Aug 3, 2026
Official guidance on U.S. census records for family-history research.
This Census Bureau page explains how decennial census records can and cannot be used for genealogy. It clarifies the 72-year privacy rule for individual census responses, points researchers toward historical census records, and publishes aggregate name-frequency data from recent censuses.
Why it stands out
- Comes directly from the federal agency that collected the census data
- Clearly distinguishes public historical records from protected recent responses
- Includes aggregate name data without exposing individual-level records
- Helps users avoid misdirected requests to the Census Bureau for records it does not provide
Good to know
- Individual decennial census responses are not public until 72 years after collection.
- The Census Bureau does not provide recent personal information or help locate missing people.
- The Age Search Service is paused for new requests effective March 4, 2026.
- Historical census record access is largely handled through the National Archives, not this page itself.
Under the radar: If you are looking for named ancestors rather than name-frequency statistics, follow the National Archives census-record path instead of starting with the Census Bureau’s current data search.

Technical Notes
