The decision to change one's last name after a wedding is no longer one made lightly especially considering everything that has to be updated from social security to passports, bank accounts and insurance.

However, in the U.S., the tradition of taking your husband's last name is still quite common, according to a survey published by the Pew Research Center.

The study surveyed 2,437 U.S. adults in opposite-sex marriages and 955 who have never been married to ask what their choice was or would be.

The study was part of a larger survey consisting of over 5,000 U.S. adults conducted between April 10-16, 2023. A random sampling of residential addresses was used to ensure nearly all U.S. adults had a chance to be selected, Pew said.
