The 72-year restriction on access to decennial census records is primarily in place for privacy reasons, specifically to protect personally identifiable information. This rule ensures that individual data collected during the census remains confidential for a significant period.
The Core Reason: Protecting Privacy
The fundamental reason behind the 72-year restriction is to safeguard the privacy of individuals. Personally identifiable information gathered during the decennial census, such as names, addresses, and other sensitive details, is restricted from public access. This measure aims to prevent the immediate or short-term disclosure of private data, allowing a reasonable period to pass before the records become publicly available for historical or genealogical research.
Historical Context and Legal Basis
The establishment of the 72-year rule was a significant development rooted in collaboration and legislative action:
- Agreement: The restriction was an outgrowth of an agreement forged between the U.S. Census Bureau and the National Archives. This collaboration was crucial in balancing the need for data collection with the imperative of protecting citizens' privacy.
- Legislative Enactment: This agreement was formally codified into law, passed in 1978. The legislation solidified the 72-year period as the standard for restricting access to sensitive census data.
This legal framework ensures that access to census records containing personally identifiable information is restricted to all but the individual named on the record or their legal heir for the specified 72-year period. After this duration, the records are typically released to the public, becoming invaluable resources for historians, demographers, and genealogists.
What Information Is Restricted?
The restriction applies specifically to personally identifiable information within decennial census records. This includes, but is not limited to:
- Names of individuals
- Specific addresses
- Other demographic data that could directly identify a living person
This ensures that while aggregate statistical data from the census is released promptly, the individual-level responses remain confidential for nearly three generations, a period believed to largely encompass the lifespan of most individuals enumerated.
