Indicators of Broadband Need Map
The Indicators of Broadband Need map was created by the United States Department of Commerce, National Telecommunications and Information Administration (NTIA). The map uses several different data sources to show information on broadband availability within the United States. Layers in this map were created using data sourced from the American Community Survey collected by the U.S. Census, Ookla, Measurement Lab (M-Lab), Microsoft and the Federal Communications Commission (FCC). In addition, there is a layer in the map that displays the locations of higher education institutions eligible as Minority Serving Institutions (MSIs) under NTIA's Connecting Minority Communities grant program. There is also a layer that shows areas designated as American Indian, Alaska Native and Native Hawaiian Areas by the U.S. Census in 2020. A list of data sources with descriptions can be found by clicking on the information widget in the map as well as instructions on how to download the county, census tract and census block level data used in the map.
Broadband Availability Data Collection
NTIA is seeking to partner with broadband service providers to collect broadband availability data at a more granular level than that available via the FCC Form 477 process. This data will be used to better assess broadband availability across the country and particularly in rural areas. Specifically, NTIA is seeking sub-Census block geographic information on service availability, such as address, address range, road centerline, land-parcel identification, or latitude/longitude and corresponding broadband availability data (such as service type, upload and download speed, etc.). Please include a completed NBAM Online Data Collection Form with any file uploads and ensure that data complies with the instructions provided in the Data Submission Guidelines document. See the Broadband Availability Data Collection Upload User Guide for detailed instructions.

National Broadband Availability Map
NTIA received funding from Congress in 2018 to update the National Broadband Availability Map (NBAM) in coordination with the Federal Communications Commission (FCC). Congress directed NTIA to acquire and utilize data from available third party datasets. NTIA built upon existing partnerships to identify data from federal, state, local and tribal governments, owners and operators of broadband networks, educational institutions, nonprofits, and cooperatives to create the map.
The NBAM is a GIS platform used to visualize and analyze federal, state, and commercial broadband data sets. This includes data from the FCC, U.S. Census Bureau, Universal Service Administrative Company, U.S. Department of Agriculture, U.S. Department of the Treasury, Ookla, Measurement Lab, BroadbandNow, White Star and the state governments. Users, including administrators from 36 participating states and four federal agencies, access the NBAM mapping platform and use these data resources to better inform broadband projects and funding decisions in their states.
