How this list is built

A name “peaked” in 1940 when that year holds its best-ever position in the national rankings — rank, not raw count, because raw counts track how many babies were born and would pile every “peak” into the boom years. To qualify, a name must have reached the top 1,000 at its height and have at least 500 all-time applications. Lists are ordered by that peak rank.

Ranks come from U.S. births, counted separately for girls and boys. “Unranked” today means fewer than 5 applications in the latest year — uncommon, never invalid.
