Lesbian, Gay, Bisexual, Transgender, Intersex, and Queer (LGBTIQ+) people’s experiences of homelessness is an under-explored area of housing and homelessness studies, despite this group making up 20–40% of homeless populations. Despite this, much of the existing literature focuses on specific elements of LGBTIQ+ homelessness, and often does not consider the intersections of these elements, instead placing them into individual siloes. Our approach is an intersectional one; this paper identifies the key themes in the existing research, and analyses how these themes interact to reinforce the discrimination and stigma faced by LGBTIQ+ people who experience homelessness. This intersectional-systems thinking approach to LGBTIQ+ homelessness can be used to develop well-informed, culturally sensitive support programes.
