Using data from the U.S. Census Bureau, this report provides demographic and economic information about same-sex couples and same-sex couples raising children in Montana. We compare same-sex “unmarried partners,” which the Census Bureau defines as an unmarried couple who “shares living quarters and has a close personal relationship,” to different-sex married couples in Montana.

In many ways, the more than 1,600 same-sex couples living in Montana are similar to married couples. According to Census 2000, they live throughout the State, are racially and ethnically diverse, have partners who depend upon one another financially, and actively participate in Montana’s economy. Census data also show that 35% of same-sex couples in Montana are raising children. However, same-sex couples, especially those with children, have fewer economic resources to provide for their families than their married counterparts: they have lower household incomes and lower rates of homeownership.
