How Lonnie's figures are worked out

  1. Counts come straight from the registrars: the US Social Security Administration (1880–2025) and the New Zealand Department of Internal Affairs (1900–2025). Nothing is scraped from another names site. The SSA files are the agency's own, retrieved from the Internet Archive's 2026 snapshot of ssa.gov (ssa.gov refuses automated requests); files unmodified.
  2. Ranks are computed against every name in that year's file, not just the ones this site publishes pages for — otherwise a rank would flatter every name we happen to list.
  3. The curve is drawn on births per 100,000 of that sex, not raw counts. Raw counts across eras are misleading: far more births were registered in 1957 than in 1890, so a flat count is a falling share.
  4. The reporting floor. Each registrar publishes a name only once it clears a threshold — 5 births of that sex in the US, 10 in New Zealand. Expressed as a share that threshold is itself a curve, and it is drawn on every chart here as the shaded band along the base.
  5. A missing year is a suppressed value, never a zero. Where the registrar published nothing, this site prints “below floor” or “<5”, the curve is broken rather than drawn across the gap, and the missing years are marked on the floor line. Lonnie was under the floor in no year of its US record.
share per 100,000 = births ÷ all births of that sex that year × 100,000
reporting floor (share) = 5 ÷ all births of that sex that year × 100,000

Lonnie in New Zealand

Lonnie never reached 10 births in a single year in New Zealand, so it does not appear in the DIA file. That is a reporting floor, not a zero — the name may still have been registered here, just never ten times in one year.

Seven years is a window, not a history. Unlike the American and New Zealand series this one cannot show you a name's arrival or its long decline — ONS publishes the full list only from 2019. England and Wales only: Scotland and Northern Ireland publish separately and are not counted here.
