The US states with the highest – and lowest –  proportion of same-sex couples living there have been revealed. 

A snapshot of the 2020 census by the Williams Institute found that there were 1,168,566 same-sex couples living together in the US.

The majority of same-sex couples cohabiting were found to be female (53.4 per cent), while 47.7 per cent of men were noted to be living together. A majority of 57.7 per cent of the total same-sex couples cohabiting are married, while 22.1 per cent of those married couples are raising their own children. 

The snapshot further highlights the US states with the highest and lowest proportions of same-sex couples, which, unsurprisingly, tend to be red states.

Coming in on top as the area with the highest proportion of same-sex couples cohabiting is the District of Columbia, which despite not being a state has 25.7 same-sex couples for every 1,000 households, amounting to 8,052 same-sex couples in total. 

Delaware, home to trans senator Sarah McBride, follows behind with 12.61 same-sex couples for every 1,000 households, amounting to 4,873 same-sex lovers, while Oregon, where state law allows trans students to compete in sex-segregated sports teams, has 12.56 couples for every 1,000 households, amounting to 21,006.
