The figures stated 61 percent of those who were unmarried had never been married while 23.8 percent were divorced and 14.4 percent were widowed.
The Census Bureau said there were 88 unmarried U.S. men for every 100 unmarried U.S. women at the time of last year's census.
The bureau said there were 6.5 million unmarried-partner households at the time of the census and 581,300 of those were same-sex households.
