The most common first names in America

Somewhere between 1990 and 2020, Michael passed James and became the most common name for a male in America. There are 3,469,434 Michaels living in the United States, about 350,000 more than the Johns and roughly half a million more than all the people named James who used to hold the top spot.

On the female side nothing moved at the very top. Mary was number one in 1990 and Mary is still number one, with 1,765,503 women named Mary. But the name right behind her tells you something about how the country changed in those thirty years.

Maria is the second most common woman's name in America. In 1990 it ranked seventh. This matches up with the growth of the Hispanic population over the same period. Maria now sits ahead of Jennifer, Elizabeth, Patricia and Linda, four names that dominated mid-century American birth certificates.

The rest of the men's list barely budged. James, John, Robert, Michael, William, and David held the top six in 1990 in a slightly different order, and they hold the top six now. Charles slipped out of the top eight and Daniel, Joseph, Richard, and Thomas filled in behind. Men's naming in America is remarkably conservative, and it has been for a couple of centuries.

Why every one of these names sounds old

These aren't the names parents are picking. They're the names of everyone alive right now, which is a very different question.

Jennifer is the clearest case. It was the number one girl's name in America for fifteen straight years, from 1970 to 1984, and hasn't cracked the top 100 for newborns since 2008. But those millions of Jennifers are in their forties and fifties, they're alive, and they all still count. Same with Karen at number ten, Linda at six, Susan at seven. Every one of them peaked decades ago.

The living population is a stack of every naming trend of the last eighty years, weighted by how many people from each era are still around. Boomers are the biggest layer, so their names sit on top. We wrote about that weight in America's record median age, and it shows up here too.

If you want the names actually being given to newborn babies, that's Social Security birth registration data, and it's a completely different set: Liam, Noah, Olivia, Emma. Those names will take another forty years to climb the living-population list. Our boy names and girl names rankings carry the birth-year series back to 1880 so you can watch a name rise and fall.

The gap between men's and women's names

There's a lopsidedness in the table. The top men's name has 3.47 million holders. The top women's name has 1.77 million. Michael alone outnumbers Mary roughly two to one, even though there are slightly more women than men in the country.

Women's names are simply spread across a wider pool. American parents have always experimented more with girls' names, cycling through fashions faster and inventing more of them, so no single women's name ever concentrates the way Michael or John does. The effect is large: the top ten men's names cover about 14 percent of the male population, the top ten women's names about 7 percent.

Surnames work differently again, and they're far more concentrated by race and origin than first names are. That's in the most common last names in America, where Smith still leads and Garcia and Rodriguez have moved into the top ten.

Living-population counts are from the U.S. Census Bureau first-name files, 2020 release, with the 1990 file used for the historical comparison. Birth-year trends are from Social Security Administration name records, 1880 to 2025. Census first-name files include names held by at least a minimum number of people, so very rare names are not published.
