Source: every name, rank, and count on this page comes from the U.S. Social Security Administration's national baby-names dataset (2025 data, from Social Security card applications). It is public-domain U.S. government data; names given fewer than 5 times in a year are excluded by the SSA, spelling variants are counted separately, and the data covers U.S. births only.
