Top Baby Names in California, 2000s — Most Popular Boys & Girls Names

What the Data Says About the 2000s in California

During the 2000s (2000–2009), the Social Security Administration recorded 1,652,225 births across the top 50 boy and top 50 girl names in California. The decade's leading boy name was Daniel with 39,616 births, while Emily was the top girl name with 30,413 births. The top 50 boys in this decade collectively accounted for 1,017,526 births versus 634,699 for the top 50 girls — a common SSA pattern in which the boy-name pool is more concentrated among fewer high-frequency choices. These totals represent only names appearing five or more times per year in California; rarer names fall below the SSA's privacy-disclosure threshold and are excluded.

The 2000s sits within a specific cultural window of U.S. naming history. Late-20th-century decades like the 2000s show accelerating naming diversity, as popular culture, television, and celebrity influence began fragmenting the top-name distribution. Daniel and Emily leading California during this window reflects how regional preferences interact with broader national trends.

Decade totals are computed by summing SSA state-year records for California across all ten years of the 2000s. Because the SSA suppresses any name with fewer than five annual occurrences in a state, the true number of unique names given in California during this decade is larger than what this page lists. The dataset also treats every spelling as a separate name — for example, Kayla and Kaylah are tracked independently — so combined-spelling totals would shift the rankings somewhat.
