RALEIGH – Newly released census estimates are arriving as North Carolina data specialists weigh how a federal privacy-policy change could affect information used by small communities to make public decisions.
The Census Bureau’s release registry lists the 2025 American Community Survey one-year products, including detailed tables and supplemental estimates, as released Oct. 29. The release is distinct from the federal policy announced in June.
The bureau’s August explanation of that policy identifies coarsening — reducing detail through measures such as rounding or grouping values — as the preferred confidentiality safeguard. Suppression, which withholds data, is allowed as a last resort. The policy disallows noise infusion, which adds random changes to published values.
The bureau says coarsening and suppression can leave less information available for small geographic areas and population groups. It has said the American Community Survey will move to compliant methods gradually, with the transition completed by 2029. Previously published products are not being changed.
That matters in North Carolina because smaller communities depend on the survey’s five-year estimates for local planning. In reporting published Oct. 29, Carolina Public Press interviewed state census liaison John Quinterno and Carolina Demography director Nathan Dollar about the potential consequences.
Their concerns center on whether less detailed information could make it harder to assess needs and plan services. The survey informs decisions involving schools, housing and health services, among other public responsibilities.
But the latest release should not be confused with a documented loss of detail. Carolina Public Press reported that a Census Bureau official said the 2025 one-year products had not lost tables, geographic coverage or granularity because of the policy.
Those one-year estimates generally cover populations of at least 65,000, with supplemental estimates reaching populations of at least 20,000. Smaller places rely on five-year data.
The impact on those five-year products remained unresolved in the reporting. The bureau told Carolina Public Press it would provide more information when available. No specific North Carolina community’s data loss has been established.
