When do men change their last names upon getting married?

Of the 877 men, only 27, or 3 percent, changed their name. Of those, 25 dropped their last name to take their wife’s and two hyphenated their last name. Among the 97 percent who kept their name, 87 percent said their wife took their last name, 4 percent said their wife hyphenated her surname while they made no change, and 6 percent said that neither changed their name. No respondents reported creating a new last name.

The study, published online in May in the Journal of Family Issues, looked at whether a man’s level of education—both his own and relative to his wife’s—influences the likelihood that he chooses a nontraditional surname in marriage.

It found that among men with less than a high school degree, 10.3 percent reported changing their surname. Among men with a high school degree but no college, it was 3.6 percent, and among men with any college, only 2 percent. None of the men surveyed who had an advanced degree changed their name.
