Beginning with 2013 ACS data products, tables reflect edit/processing changes which show same-sex married couples along with all married couples. Tables that have a line for "married couples" will include same-sex married couples, unless otherwise noted, and the marital status for those adults will be shown as "now married" or "married, spouse present." In 2013 data, there are 251,695 same-sex married couple households, which constitute 0.45 percent of all married couple households. For more detail on same-sex married couples, view the Characteristics of Same-Sex Couple Households table package.
