The 2024 ACS 1-Year PUMS file has not yet been released amidst the U.S. federal government shutdown. Once these data are available, IPUMS will process and release them as quickly as possible.

Description

SSMC reports whether the head of household and spouse are a same-sex married couple. Beginning in the 2013 ACS/PRCS, same-sex married couples are included in the "married spouse present" category. As well, beginning in 2013, family household and married-couple families include same-sex married couples.

Prior to the 2013 ACS/PRCS, same-sex married couples were recoded by the Census Bureau from married to unmarried partners. The 2012 ACS/PRCS included a data quality flag identifying same-sex married couples that had been recoded (QRELATE = 9 "Same sex spouse changed to unmarried partner").

User Note: Same-sex married couples are only shown as the householder and spouse, and are not included in subfamilies. Respondents with an SSMC value of 1 were logically allocated as a same-sex married-couple, even though they were missing valid responses for SEX or RELATE. See the SSMC and Family Interrelationship page for information on how the IPUMS-USA family interrelationship variables interact with same-sex married couple households.
