United States Name Data Limitations

United States Name Data Limitations for United States official name statistics, including statistical scope, derivation rules, coverage, and suppression.

Source limitations

Names with fewer than five applications for a sex and year are omitted

A missing name can mean that the source suppressed it, omitted it, or that it did not meet publication eligibility. It does not prove that the name was unused.

  • Coverage: 1880–2025
  • Source categories: Female and male categories as published by SSA

Cross-market comparisons

Raw counts from different markets are not combined. Market populations, registration systems, suppression, and coverage can differ.
