Social support is closely connected to mental health and well-being as well as experiences of housing vulnerability. This study explored differences between homeless and vulnerably housed women in their experiences of social support. Forty-nine homeless and 43 vulnerably housed women completed 3 measures to assess their social networks, social support networks, and global social support. Vulnerably housed women reported fewer social support network members than homeless women. Social support network size was found to be a predictor of global social support score. These findings suggest that housing status impacts social support in homeless and vulnerably housed women, which may have implications for their well-being.
