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.
