US birth records, 1890 to 2025
Names that switched sides
14 names went mostly to one sex between the 1920s and the 1960s and mostly to the other from the 2000s on. Take Aubrey: girls were 4% of the babies given that name in those middle decades, and 97% of the ones given it since 2000. Every figure on this page is from US Social Security birth records.
Girls Boys
Now mostly girls
Now mostly boys
On the way
A looser rule catches 6 more: mostly one sex from the 1900s to the 1930s, and at least three in four the other way in the 2010s and 2020s.
How this list is made
A name reaches the two main lists when at least 3,000 babies were given it in each window, girls were under 35% of them from the 1920s to the 1960s and over 80% from the 2000s on, or the same the other way round.
The third list uses a second, looser rule: two shorter periods, the 1900s to the 1930s against the 2010s and the 2020s, with the line drawn at 25% and 75% instead of 35% and 80%.
The decade named beside each name is the first one from which every later decade with at least 100 births holds the new majority.
One caution about the 2020s: here they cover 2020 to 2025, six years rather than ten, because that is as far as the record goes.
These are United States figures. The Social Security Administration publishes the names given to babies born in each year, and it holds back any name given to fewer than five babies of one sex in a year, so a name can be missing from a year without having gone unused.
The cut-offs on this page are ours, not the agency’s.
Only names that have a page here are listed, so every name on this page opens onto its full record.
