Top Baby Names of the 1900s

What the Data Says About the 1900s

The Social Security Administration's 1900s national files cumulate 2,306,181 births across the top 50 boy and top 50 girl names for the decade. John led the boys with 84,590 births, while Mary led the girls with 161,504 births. The top 50 boys of the 1900s collectively captured 829,596 births versus 1,476,585 for the top 50 girls — the typical SSA pattern in which a narrower set of boy names dominates a wider share of total registrations. Names occurring fewer than five times in a given year are suppressed by SSA for privacy, so these totals represent only the public-disclosure portion of the decade's actual naming distribution.

The 1900s occupied a specific cultural moment in U.S. naming history. Before 1920, the top ranks were monopolized by traditional Anglo-American and biblical names — John, William, Mary, and Helen appearing year after year with little turnover.

Decade totals on this page aggregate SSA national name-year records across all ten years of the 1900s. Because the SSA excludes names with fewer than five annual occurrences, the true number of unique names given during the 1900s is substantially higher than the top-50 lists shown here — particularly for rare and emerging names that never crossed the disclosure threshold. Each spelling is also tracked as a separate entry, so combined pools (e.g., Sophia + Sofia, Aiden + Ayden) would produce different rankings.
