Last Name Facts

A last name, also referred to as a surname or family name, is typically the last part of the full name that identifies a person.
Last names have many origins including a persons occupation, location, tribe, community, status, or derived from the father's first name.
In many parts of the world, the last name is placed before the first name.
In Mexico and other Spanish and Portuguese speaking countries, it is common to have 2 last names.
Some last names are related to religion, such as the Jewish last name Cohen, which means “priest”.
Some last names are related to nobility or royalty, such as Anderson, which is derived from the name Anders, which means “son of the ruler”.
Many immigrants change their last name upon arriving in a new country to blend in or to honor their heritage.
Some last names have multiple spellings, such as spelling Smith with an “e” at the end or with a “y” at the end.
In some countries, such as Japan, the last name is used to denote the family’s social standing.
Some last names are based on a physical characteristic or feature, such as Long, Short, and Small.
Some last names are based on nicknames or descriptive words, such as Brown, White, and Black.
Last names can also be based on an occupation, such as Baker, Taylor, and Butcher.
Some families use a combination of the mother and father's last names, such as the Spanish last name Garcia Lopez.
Many last names originate from geographical locations, such as the name Smith, which originated in England.
Last names have been in existence since the 11th century, when they were used to identify people by their place of birth, occupation, or other characteristics.
The popularity of certain last names can be influenced by historical events, migration patterns, and cultural trends. For example, the last name "Gonzalez" is one of the most common surnames in the Spanish-speaking world, while the last name "Smith" is one of the most common in English-speaking countries.
In some cultures, last names are used to indicate a person's gender. For example, in Iceland, last names are based on the father's first name and indicate whether the person is male or female.
Last names can provide clues about a person's ancestry or family history. For example, a person with the last name "Smith" may have ancestors who worked as blacksmiths.
The use of last names is believed to have originated in Europe during the Middle Ages. At this time, people were beginning to move away from small, isolated communities, and last names were needed to help identify individuals in larger, more diverse populations.
Last names can also be used to identify a person's nationality or ethnic background. For example, a person with the last name "Nguyen" is likely of Vietnamese origin.
In many countries, there are specific laws governing the use of last names. For example, in Japan, couples must choose the same last name when they get married, and there are restrictions on changing one's last name.

Definitions and scope

This generator samples from the top 1,000 surnames in the United States Census Bureau 2010 surname data stored by this site.

Census aggregates cover surnames reported in the 2010 Census. This is a historical frequency list, not a live directory and not an identity database.

Worked example

Generate five surnames. Each result is drawn from the stored top-1,000 list. Output order is random and does not show Census rank unless checked against source data.

Assumptions and limitations

Names outside the top 1,000 cannot appear. Punctuation, spacing, capitalization, and later population changes may not be represented as a user expects.

A common surname does not reveal an individual's ancestry, race, nationality, language, or relationship to another person with that name.

Common mistakes

Common mistakes include calling 2010 data current, treating a generated name as unique, and inferring personal attributes from aggregate surname statistics.

Privacy and accuracy

The tool loads aggregate data locally and takes no personal input. Census notes that its published aggregates do not identify individuals.
