#1,872girls’ names · US 2025

Judy was the 1,872nd most registered girls' name in the United States in 2025, on 105 births.

Its moment was 1947, when 21,037 babies were given it. In 3 of the years between, the name fell under the 5-birth floor and the registrar published nothing — those years are the marks along the base of the chart, not gaps in the name's use.

How Judy'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. Judy was under the floor in 3 years 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

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.
