The Most Common Last Names in America

Start with the simple fact at the top of the list. Smith comes in at 2,369,644 people, well ahead of anything below it. The next name down, Johnson, has 1,858,234. That gap of more than half a million is the single largest jump anywhere in the rankings. No other pair of adjacent names is separated by so much. Smith isn't just the most common American surname. It sits in a tier of its own.

Look at the five names at the top and you see one source. Smith, Johnson, Williams, Brown, and Jones are all English, Welsh, or broadly British in origin. They are occupational and patronymic names that came over early and spread fast. Together they account for roughly 8.5 million people. If you were guessing at the American name list from a distance, this is the part you'd get right. It's the composition behind these names that tells the harder story.

Here are the 25 most common surnames in the United States, with the racial and ethnic composition of the people who carry each one. Click any name to see its full profile.

The numbers under the names

Smith is 68.0% White and 22.6% Black, with 3.5% Hispanic. That Black share is not an accident of the alphabet. After emancipation, many formerly enslaved people took or kept English surnames, sometimes the name of a former enslaver, sometimes a common name chosen freely, sometimes a name already carried for generations. The result shows up in the data more than a century later. The most ordinary names in America carry that history in their proportions.

Move down the top five and the pattern sharpens. Johnson is 56.8% White and 33.6% Black. Brown is 55.4% White and 34.7% Black. Jones is 53.1% White and 37.2% Black. The Black share climbs as you go. Then you reach Williams at rank three, and the line crosses. Williams is 46.2% Black and 43.8% White. More people named Williams identify as Black than as White. It's one of the most common surnames in the country, and it's a majority-minority name.

Davis, at rank nine, fits the same shape: 59.6% White, 30.8% Black. These are not edge cases buried deep in the data. They're five of the twenty most common names in the United States, and the racial math inside each one is a direct record of how naming worked in the decades after 1865.

The Hispanic surge into the top fifteen

Now watch what's happened to the middle of the list. Garcia sits at rank six with 1,149,510 people, 91.2% of them Hispanic. Rodriguez is eighth, Martinez tenth, Hernandez eleventh. Lopez and Gonzalez land at twelve and thirteen. Six of the top fifteen surnames in America are now Hispanic-origin names, and each one is between 91% and 94% Hispanic. Hernandez alone is 94.1%.

This concentration is far tighter than anything among the Anglo names. Where Smith and Williams are split across groups, Garcia and Rodriguez and Gonzalez are overwhelmingly one. A name like Gonzalez (94.4% Hispanic) functions almost as a single-group marker in a way that Brown or Jones never could. The surge isn't only that these names rose in rank. It's that they brought a level of demographic concentration the top of the list hadn't seen before. Perez and Sanchez carry the pattern further down, at ranks twenty-one and twenty-five, both above 92% Hispanic.

The names that cross lines

Two entries are worth sitting with because they don't behave like the rest. Jackson, at rank twenty, is 51.2% Black and 38.3% White, a clear majority-Black surname in the top twenty and another marker of post-emancipation naming. And Lee, at rank nineteen with 695,657 people, is the genuine bridge name in the data: 43.9% Asian, 33.2% White, 15.3% Black. Lee is at once a common Korean and Chinese romanization, a Southern English and American surname, and a name carried by Black families. No other top-25 name spreads across origins the way Lee does. One spelling, three very different histories feeding into it.

The broad shape, then, is this. English-origin names still hold the top of the list by volume, led by a Smith that towers over everything. But the composition under those names records emancipation, with several of them near or past a Black majority. Hispanic surnames have pushed into the top fifteen in force and in concentration. And a name like Lee shows the list isn't sorted by origin at all, only by how many people answer to it.

If your own last name is anywhere in here, or nowhere near it, the interesting question is the breakdown behind it. You can look up any surname's rank, the number of people who carry it, and its racial composition over at the CensusEasy names section. The list above is just the loudest twenty-five. The story I find most worth reading is the one inside whatever name you check first.
