The IGH Global Framework captures three broad categories of people who may be considered homeless, defined as “lacking access to minimally adequate housing.” For local definitions, countries or cities may include some of these categories and not others. Rather than a list that must be accepted in full everywhere, the Framework offers a shared vocabulary for collaboration across countries. Within the Framework, IGH targets programs and research primarily toward those in Category 1 and in a subset of Category 2.
