The Committee to End Homelessness in King County produced a helpful visualization tool that compares the size of homeless populations around the country as well as the type of housing support they receive.

Ben Schiller reports on a new visualization tool developed by the Committee to End Homelessness in King County in connection with the recent Hack to End Homelessness event in Seattle. The Haystack tool "compare rates of homelessness (per 1,000 people) for 25 cities, and show whether the homeless are fully unsheltered, in nightly shelters, or in transitional or permanent accommodation." The data for the maps pulls from "one night count" data provided by the U.S. Department of Housing and Urban Development.
The article also includes a few other examples of GIS-enabled mapping tools that could help connect homeless with services.
