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 with states and local governments to identify data from state, local and tribal governments, owners and operators of broadband networks, educational institutions, nonprofits, and cooperatives to create the map.

National Broadband Availability Map Reaches 20-State Milestone

July 10, 2020

NTIA’s National Broadband Availability Map (NBAM) reached a 20 state milestone with the addition of Wyoming and Washington State. 

The NBAM is a geographic information system platform which allows for the visualization and analysis of federal, state, and commercially available data sets. This includes data from the Federal Communications Commission, U.S. Census Bureau, Universal Service Administrative Company, U.S. Department of Agriculture, Ookla, Measurement Lab, and the state governments. The mapping platform provides users, including administrators from the 20 participating states, with access to the NBAM and its data to better inform broadband projects and funding decisions in their states.

40 percent of the states now participate in the NBAM. This positive momentum will better equip policymakers as we work together to expand broadband Internet coverage across the United States.

NTIA Adds 5 States to National Broadband Availability Map

June 3, 2020

By NTIA

NTIA today is announcing the addition of five states to its National Broadband Availability Map (NBAM) program. Wisconsin, Colorado, Illinois, Oregon, and New Hampshire join 13 other states who are partnering on this critical broadband data platform.

The NBAM is a geographic information system platform which allows for the visualization and analysis of federal, state, and commercially available data sets. This includes data from the Federal Communications Commission, U.S. Census Bureau, Universal Service Administrative Company, U.S. Department of Agriculture, Ookla, Measurement Lab, and the state governments. The mapping platform provides users, including administrators from the 18 participating states, with access to the NBAM and its data to better inform broadband projects and funding decisions in their states.

With the addition of five new states, the NBAM is another step closer to creating a national platform that can help inform policymakers and expand Internet coverage across the United States.

Broadband is More Important Than Ever

April 10, 2020

Broadband is more important than ever, and the National Telecommunications and Information Administration (NTIA) has been working to expand access and increase connectivity for all Americans.

We recently provided a one-year update to the American Broadband Initiative (ABI), the Trump Administration’s government-wide approach to connectivity challenges. Five new states – Nebraska, New Mexico, Michigan, Missouri, and Virginia – have joined the initial eight states participating in our National Broadband Availability Map.

We have seen increased participation in our State Broadband Leader’s Network, and our BroadbandUSA website now has the most comprehensive information on state resources available.

At NTIA, we have also worked with the FCC, businesses, and federal stakeholders to make sure our response to connectivity needs remains flexible. Most recently, NTIA supported Verizon’s application to the FCC for a Special Temporary Authority to access radio frequency spectrum due to increased commercial use.

We plan to continue our hard work to meet the needs of the American people.
