The Census Bureau announced today that more than one-in-four same-sex couples counted in the 2010 Census was likely an opposite-sex couple, and identified a confusing questionnaire as a likely culprit. The bureau released a new set of “preferred” same-sex counts, including its first tally ever of same-sex spouses counted in the census.
The official count of same-sex couple households from the 2010 Census: 901,997. The new preferred count: 646,464, meaning that 28.3% of the same-sex couples counted was likely an opposite-sex couple. Of the households in the official count, 552,620 were unmarried couples and 349,377 described themselves as spouses. The new preferred count: 514,735 unmarried couples and 131,729 married couples.
Even this revised same-sex spouse count is likely high, the Census Bureau said, citing estimates that perhaps 80,000 same-sex couples in the U.S. are legally married (although another 85,000 could be in same-sex civil unions). As a previous posting here explained, some same-sex couples in civil unions may believe that calling themselves married is a better description of their relationship than unmarried partner, according to previous census research.
