Top Baby Names of 1900

What the Data Says About 1900

The Social Security Administration's national 1900 file shows 316,263 births concentrated in the top 100 boy and top 100 girl names, the segment of U.S. baby-name data released to the public for that year. The #1 boy name of 1900 was John, with 9,828 births registered nationally. The #1 girl name of 1900 was Mary, with 16,705 births nationally. The top 100 boys captured 112,333 births compared with 203,930 for the top 100 girls — consistent with the historical SSA pattern in which a smaller pool of boy names dominates a larger share of annual births while girl names are more evenly distributed.

1900 sits within a specific era of U.S. naming trends. Pre-1940 years are dominated by traditional biblical and English names — John, William, Mary, and Helen consistently occupy the top ranks, and the top 10 names account for a much larger share of all births than in later decades. John and Mary leading 1900 fits this broader cultural signature.

These rankings come directly from Social Security Administration card applications and represent approximately 96% of all U.S. births in 1900. Names with fewer than five occurrences nationally in 1900 are excluded from SSA's public file to protect privacy, meaning the true number of unique names given in 1900 is significantly larger than any public top-100 list can show. Each spelling variation is counted separately — Sophia and Sofia, Aiden and Ayden — so rankings reflect only the specific spelling filed on the SS card, not combined name pools.
