Top Baby Names of 1991

What the Data Says About 1991

The Social Security Administration's national 1991 file shows 2,257,833 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 1991 was Michael, with 60,807 births registered nationally. The #1 girl name of 1991 was Ashley, with 43,477 births nationally. The top 100 boys captured 1,301,467 births compared with 956,366 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.

1991 sits within a specific era of U.S. naming trends. Late-20th-century years like 1991 reflect accelerating naming diversification, with Jennifer, Jessica, Michael, and Christopher giving way to more varied choices and the gradual fragmentation of top-10 dominance. Michael and Ashley leading 1991 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 1991. Names with fewer than five occurrences nationally in 1991 are excluded from SSA's public file to protect privacy, meaning the true number of unique names given in 1991 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.
