The Response Outreach Area Mapper (ROAM) application was developed to make it easier to identify hard-to-survey areas and to provide a socioeconomic and demographic characteristic profile of these areas using American Community Survey (ACS) estimates available in the Planning Database. Learning about each hard-to-survey area allows the U.S. Census Bureau to create a tailored communication and partnership campaign, and to plan for field resources including hiring staff with language skills. These and other efforts can improve response rates. To learn more see The Low Response Score (LRS): A Metric to Locate, Predict, and Manage Hard-to-Survey Populations and The 2020 Census at a Glance: Plan Census Outreach with the Response Outreach Area Mapper tool.
