Data Sources, Provenance & Methodology
HowManyOfMe.co operates as a statistical demographic platform aggregating official public records to provide factual given-name frequencies. Our calculations distinguish between observed historical registrations, decennial census enumerations, and derived actuarial models:
- U.S. Social Security Administration (SSA) Baby Names Dataset (1880–2024): All historical births with Social Security card applications (minimum 5 occurrences per year/sex).
- U.S. Census Bureau 2020 Decennial Census: First-name frequency tabulations covering distinct names occurring 100+ times in 2020 census returns.
- Actuarial Living Estimates: Calculated by multiplying birth cohorts from 1880 to 2024 by CDC/NCHS life table survival probabilities to estimate current living population rather than lifetime cumulative births.
- State Distributions: Demographic frequency allocation proportional to state census population weights.
