Field Testing and Validation of a New Question Set to Measure Housing Status - Fulton County, Georgia, August-September 2023.

Although data on housing status can guide health promotion and effective public health response, a validated question set to measure housing status is not available. In June 2023, the Fulton County Board of Health (FCBOH) requested CDC technical assistance to field test a housing status question set for public health case interviews and surveillance. The question set can be asked of any relevant period to determine both homelessness status and residence in a congregate setting. Field testing was performed at food pantries and FCBOH tuberculosis, vaccination, and sexual health clinics in Fulton County, Georgia, during August 2-September 1, 2023. Among 481 respondents who were asked about their living situation during the previous 2 weeks, 139 (28.9%) reported experiencing homelessness and 75 (15.6%) reported living in congregate settings. Twenty-six of these 481 respondents were identified in a local housing database (the Homeless Management Information System [HMIS]); for 24 of these 26 respondents (92%), the housing status recorded in HMIS matched that determined by the question set. The question set would benefit from validation in additional settings and could help health agencies improve housing data accuracy and consistency, optimizing measures to assist persons at higher risk.
