What the Data Says About Names Starting with C

The Social Security Administration's national baby-name archive contains 6,716 distinct names beginning with the letter C, out of roughly 104,000 total names tracked since 1880. On this page (sorted by name), the leading entry is Cosette with 2,964 cumulative births and a current national rank of #1908. Within the 50 names on this page, 29 are classified as boys' names and 21 as girls' names in SSA records — reflecting the overall letter-level split for {letter}. Every name shown has appeared five or more times in at least one year of SSA data — rarer spellings fall below the disclosure threshold and are not included.

Of the 50 names displayed, 12 currently rank within SSA's annual top 1,000 for their gender — making them actively popular rather than historical-only entries. Combined, these 50 names represent 19,282 births across all years of the SSA archive. Letter-level patterns reveal broader naming conventions: some letters (J, M, S) dominate both boys' and girls' name distributions, while others (U, Y, Q, X, Z) are comparatively rare starting letters in English naming traditions. The distribution of names starting with C reflects both the English-language convention inherited from the Anglo-American majority and the steady contribution of international names (Spanish, Arabic, Asian, African origins) added to the U.S. naming pool over the past century.

All figures on this page derive from publicly released SSA baby-name files, which record the first name on every Social Security card application for U.S. births. Names are tracked by exact spelling, so homophones and near-variants (Sarah and Sara, Aiden and Ayden) count as separate entries; combining them would substantially change the ordering. Peak-year and rank data are drawn from the same SSA files and reflect name-year records with five or more occurrences. This listing is paginated in groups of 50 — across all letter-C names, there are 135 total pages at this sort order. This page is provided for informational and research purposes only and does not constitute naming, legal, or genealogical advice.
