Years covered

Across 51 jurisdictions (50 states + DC), the SSA tracks 2,335,053 state-name-year-gender combinations from 1910 to 2025. In 2025, Liam was the #1 boy in 15 of 51 states; Charlotte was the #1 girl in 28 of 51. The "national #1" label hides genuine geographic disagreement — 36 states picked a different boys' name. By population weight, California is the largest contributor — 22,880,824 tracked births alone. All-time, Mary has held a state-level #1 spot in 1,933 state-years across 51 different states — the most dominant single name in US naming history.

The "National #1" Doesn't Mean Universal #1

In 2025, here is how state-level #1 picks were distributed. A long bar = many states picked that name; a short bar = a regional minority preference.

Even when a single name dominates the national rankings, state-by-state distribution reveals fault lines that the headline number hides. In 2025, the boys' #1 winner Liam won the top spot in only 15 of 51 states; the remaining 36 picked from 7 alternate names. On the girls' side, Charlotte won 28 of 51, with the rest split among 8 other names. Each state's preference reflects local demographics, immigrant history, religious traditions, and recent cultural events — the bars below are the visible signature of all four forces interacting.

Geographic Spread of the SSA Dataset

A handful of large states dominate the totals. Smaller-population states have proportionally less data — earlier years in particular fall below the 5-name SSA privacy threshold and may be empty.

All-Time State-#1 Champions (1910–2025)

Names that captured the state-level #1 spot across the most state-years over a century of records. Counts the cumulative state-year-gender slots a name has owned.

The all-time pole-position champion is Mary (girls) — held the #1 spot in 1,933 different state-year combinations across 51 distinct states. Second-most: Michael (boys) at 1,410 state-years. These mid-century champions held #1 across decades when single names dominated. Modern #1 names — Liam, Emma, Olivia — accumulate state-years much more slowly because today's name pool fragments faster: a typical 2020s state #1 holds the spot for 1–4 years before being displaced.

Name	Sex	State-years at #1	Distinct states
Mary	F	1,933	51
Michael	M	1,410	51
James	M	908	35
Robert	M	886	37
Jennifer	F	676	51
