Pew Research Center says it is possible. Other research seems to be bearing it out:
In new research presented at this month’s Population Association of America conference, bureau analysts reported that the 2010 census overcount of same-sex married couples may have been even worse than previously reported. When researchers matched census records for individual couples with Social Security files, 73% of same-sex married couples counted in the census turned out to be opposite-sex married couples in Social Security files. The analysts also looked at results from a separate census survey that asked the same question (the American Community Survey), and found that 57% of who marked themselves as same-sex married couples were actually opposite-sex married couples, according to Social Security files.
The 2012 American Community Survey estimated there are about 182,000 U.S. same-sex married couples compared with about 56 million opposite-sex married couples.
That's a pretty small percentage and, one might conclude from all the hubbub over same-sex marriage, practically nothing. Does that suggest that both sides are making too much of the issue?
