The most popular last names in the U.S might be unchanged from the previous decade, but Asian surnames were the fastest-growing at the start of this decade. The U.S. Census Bureau reported Tuesday that "Smith," "Johnson," "Williams," "Brown," and "Jones" were the top five last names in the U.S. in 2020, unchanged from 2010. The fastest-growing surnames from 2010 to 2020 were Asian, including “Zhang,” “Liu,” and “Wang.” The most popular male first names were "Michael," "John," "James," "David," and "Robert," while "Mary," "Maria," "Jennifer," "Elizabeth," and "Patricia" topped the female list. Unlike the Social Security Administration’s annual count of baby names, the Census Bureau’s tally includes everyone, not just newborns.
