Response Outreach Area Mapper (ROAM)
The Response Outreach Area Mapper (ROAM) 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.

ROAM Map Services
The GeoServices REST Specification provides a way for web clients to communicate with geographic information system (GIS) servers through Representational State Transfer (REST) technology. Documentation for this service is owned and maintained by Esri, more information and specifications can be found in the ArcGIS REST APIs technical documentation.
Vector tile services are a format that allows for the display of a large amount of data (e.g., showing census tracts for the entire nation at small scales). Documentation for this service is owned and maintained by Esri, more information can be found in the ArcGIS Vector Tile Service technical documentation.

* The REST endpoint is intentionally disabled. You can add "?f=pjson" to the end of the URL to view its details. You can add the endpoint as it exists in the table directly into a desktop GIS or web map.
