Cathleen was the 9,457th most registered girls' name in the United States in 2025, on 10 births.

peak 1958 · 1,159188019532025

Its moment was 1958, when 1,159 babies were given it. In 2 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 Cathleen'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. Cathleen was under the floor in 2 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

Births per 100,000 of that sex, so eras compare fairly. The shaded band is the 5-birth reporting floor — under it the registrar publishes nothing, so a line that stops has left the record, not fallen to zero. Cathleen in the United States, 1880–2025

Between 2016 and 2025 the name has been falling — down 31% as a share of girls' births.

Cathleen in New Zealand

Cathleen 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.

Cathleen in England & Wales

Cathleen does not appear in the ONS list for England and Wales. That means it was given to fewer than 3 babies in every year from 2019 to 2025 — not that it is unused there. ONS publishes only those seven years, so a name that had its moment in England before 2019 is invisible here however common it once was.
