Source. The U.S. Social Security Administration publishes one row per state, sex, year, name, count, drawn from a 100% sample of card applications. National figures here are summed across all 50 states + DC, so they exclude births with no state recorded. Names given to fewer than five babies in a state-year are withheld for privacy, so very rare names may not appear. This page embeds every name for 1960–2025.
Rarity / "1 in N." For a chosen birth year a five-year cohort window is taken (the year ± 2). The name's count across that window is divided by the same-sex births recorded in the same window and scope (national or the selected state), giving the share of that cohort carrying the name. The dot field shows that share out of 1,000.
Trend & rank. Trend compares the name's smoothed share over recent years against five years earlier. The trajectory chart toggles between the raw count of babies given the name each year and the name's rank among all same-sex names that year. Everything respects the chosen state filter.
