Top Baby Names of 1905

What the Data Says About 1905

The Social Security Administration's national 1905 file shows 294,093 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 1905 was John, with 8,059 births registered nationally. The #1 girl name of 1905 was Mary, with 16,067 births nationally. The top 100 boys captured 97,324 births compared with 196,769 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.

1905 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 1905 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 1905. Names with fewer than five occurrences nationally in 1905 are excluded from SSA's public file to protect privacy, meaning the true number of unique names given in 1905 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.
