The third phase of the HUD-sponsored Housing Discrimination Study (HDS 2000) uses paired testing to estimate the incidence of discrimination American Indians face when they search for housing in metropolitan areas. Building upon the basic testing protocols implemented in previous national studies and in Phases I and 2 of HDS2000, and using random samples of advertised housing units in Minnesota, Montana and New Mexico--three states where substantial numbers of American Indians live in metropolitan areas--the study sends minority and white test partners to inquire about the availability of the advertised units. The research found that American Indians face significant levels of housing discrimination, primarily due to denial of information about the availability of housing units.
