“What’s in a name?” Shakespeare’s Juliet asked that rhetorical question more than 500 years ago. This question still rings true today in 21st century America. Names tell a story – they can help shed light on heritage as well as on America’s population makeup.

For centuries, people have come to the U.S. to escape war, oppression, and poverty, or to pursue employment opportunities and success. Most Americans can trace their roots to immigrant ancestors. 24/7 Tempo reviewed Census data to find the 50 most common last names in the U.S.

Last names, also called surnames, can be traced to the early years of the Middle Ages, when most people in Europe were farmers and lived in small villages. Back then, everyone knew each other, and last names were unnecessary. That changed as the population began to grow.

Today, the vast majority of the most common surnames in the U.S. can be traced back to England and other European origins. Among the top 50 most common surnames, 12 have Spanish, Cuban, or Mexican heritage. All 12 Spanish-origin names found on this list have dramatically increased since they were last counted in 2000 — a stark contrast to English names that are mostly growing at a slower pace. The most common names in general in the United States all grew in numbers between 2000 and 2010, except one — Hall saw a 16% decrease. These are the most common last names in every state.
