The U.S. Census Bureau recently released the 2010 Census surnames product, a table of all last names occurring at least 100 times in the 2010 Census returns. For each of the 162,000 last names, the table includes its frequency, national rank, and breakdown by Hispanic origin and race category. Despite the nation’s growing racial and ethnic diversity, the five most frequent American surnames in 2010 remained the same as in 2000 and were mainly reported by whites and blacks.
Smith, Johnson, Williams, Brown and Jones were the most common last names, according to a Census Bureau analysis of the 2010 Census.
This is the third in a series of data releases based on names recorded in the decennial census. Previous products tabulated name frequency from the 1990 and 2000 Censuses. The complete product, along with a methodology document, is available here.
