The U.S. Census Bureau released today new statistics on same-sex married couple and unmarried partner households. According to revised estimates from the 2010 Census, there were 131,729 same-sex married couple households and 514,735 same-sex unmarried partner households in the United States.
The results of the 2010 Census revised estimates are closer to the results of the 2010 American Community Survey (ACS) for same-sex married and unmarried partners. The 2010 ACS estimated same-sex married couples at 152,335 and same-sex unmarried partners at 440,989.
The new, preferred figures revise earlier estimates of same-sex unmarried partners released this summer from the 2010 Census Summary File 1 because Census Bureau staff discovered an inconsistency in the responses in the 2010 Census summary file statistics that artificially inflated the number of same-sex couples. In addition, a breakdown of couples who reported as same-sex spouses is now available. The summary file counts originally showed that there were 349,377 married couple households and 552,620 same-sex unmarried partner households.
