The post The 15 Most Common Last Names in America, According to the Census first appeared on Crafting Your Home.
The U.S. Census Bureau’s 2020 surname data offers a fascinating look at the family names that appear most frequently across the United States. These names are more than just labels; they carry traces of history, migration, occupations, languages, and cultural traditions that have shaped the country over hundreds of years.
The Census counts surnames reported in Census responses, but it does not reveal private family trees or prove that people with the same surname are related.
Smith , 2,369,644 people
Smith tops America’s most common surnames list, with more than 2.3 million people sharing the name in the 2020 Census. The surname comes from the Old English word smið, meaning a person who worked with metal, especially a blacksmith. Centuries ago, occupational names were common because people were often identified by their trade or profession.
A person who made tools, weapons, or household items from metal could simply become known as “the smith.” Over time, this job title became a hereditary family name passed down through generations.
Johnson , 1,858,234 people
The surname Johnson means “son of John” and belongs to a group of names known as patronymic surnames, which were originally created from a parent’s given name. The name has English, Scottish, Irish, and Scandinavian connections and spread across America through different waves of migration and settlement.
Because the name developed in multiple communities, people named Johnson do not necessarily share a single family origin.
Williams , 1,561,395 people
Williams means “son or descendant of William” and has strong roots in English and Welsh history. The name became common in the United States through early European settlement and later spread widely across many American communities.
Like many popular surnames, Williams represents numerous unrelated family lines rather than one single ancestry.
Brown , 1,386,083 people
The surname Brown is a descriptive name that generally refers to someone associated with the color brown, possibly describing hair, complexion, clothing, or another physical feature. Similar surnames developed in different places, meaning the name can have many independent origins.
Today, Brown is one of the most recognizable surnames in America and appears across many cultural and historical backgrounds.
Jones , 1,383,250 people
Jones is another patronymic surname, meaning “son of John.” It is especially associated with Wales, where naming traditions helped make it one of the region’s most common surnames.
Through Welsh migration and English settlement in North America, Jones became firmly established as one of America’s most familiar last names.
Garcia , 1,149,510 people
The surname Garcia reflects the long history of Spanish-speaking communities in the United States. While many people associate the name with more recent immigration, its history in America dates back to Spanish colonial settlement in regions now part of the United States.
Later migration from Mexico, Puerto Rico, Cuba, Central America, and other Spanish-speaking areas also contributed to the name’s growth.
Miller , 1,129,186 people
The surname Miller originally described someone who worked at or operated a grain mill. Like Smith, it is an occupational surname that developed from a person’s everyday work.
The name has English, Scottish, and German connections, with related forms including Müller and Mueller. It was already among America’s top surnames as far back as the first U.S. Census in 1790.
Rodriguez , 1,085,838 people
Rodriguez means “son of Rodrigo” and comes from Spanish naming traditions. The surname has deep roots in Spanish-speaking communities throughout the Americas.
According to the Census, Rodriguez moved from ninth place in 2010 to eighth place in 2020, making it the only surname among the top 15 to change position during that period.
Davis , 1,074,448 people
Davis means “son of David” and has Welsh and English origins. It became widespread through early settlement in North America and later spread among many different communities.
Like other common surnames, Davis has multiple historical pathways and cannot be traced to one single family line.
Martinez , 1,039,848 people
Martinez means “son of Martín” and is another Spanish patronymic surname.
The name became common through Spanish colonial history and later migration from Mexico, Puerto Rico, Cuba, Central America, and other parts of the Spanish-speaking world.
Hernandez , 1,012,486 people
Hernandez means “son of Hernando” or “son of Fernando.” It has Spanish origins and became increasingly common in the United States as Hispanic-origin populations grew.
The name reflects centuries of Spanish-language naming traditions carried across different regions and generations.
Lopez , 853,251 people
Lopez means “son of Lope” and has roots in Spanish history. The surname appears throughout Spain, Latin America, and communities influenced by Spanish settlement.
Its presence in the United States reflects both early Spanish history and later migration patterns.
Gonzalez , 833,596 people
Gonzalez means “son of Gonzalo” and follows the same Spanish patronymic tradition found in names such as Rodriguez and Martinez. It became widespread through Spanish-speaking communities across the Americas and remains one of the most recognizable Hispanic surnames in the United States.
Wilson , 787,143 people
Wilson means “son of Will,” with Will being a shortened form of William. It has English, Scottish, and Northern Irish roots and has been present in America since colonial-era settlement. Today, it remains one of the country’s most common family names.
Anderson , 766,307 people
Anderson means “son of Andrew” and has Scottish, English, and Scandinavian origins. Like other patronymic names, it began as a way to identify someone by their parent or ancestor before becoming a permanent family surname. Pasted text
These 15 surnames tell a bigger story about America itself. Some names came from occupations, some from family relationships, and others from languages carried across oceans through migration. However, a surname alone cannot determine a person’s ancestry, ethnicity, or family history. A name may have many origins and may belong to people from very different backgrounds.

Behind every common last name are thousands of individual stories, making America’s surname map a fascinating reflection of the country’s diverse history.
