About National Broadband Map

The National Broadband Map (NBM) is a searchable and interactive website that allows users to view broadband availability across every neighborhood in the United States. The NBM was created by the National Telecommunications and Information Administration (NTIA), in collaboration with the Federal Communications Commission (FCC), and in partnership with 50 states, five territories and the District of Columbia. The NBM is part of NTIA's State Broadband Initiative. The NBM is updated approximately every six months and was first published on February 17, 2011.

The State Broadband Initiative was created by the NTIA, to encourage economic growth by facilitating the integration of broadband and information technology into state and local economies. In addition to the NBM, the State Broadband Initiative accomplishes this goal by providing grants. NTIA has awarded a total of $293 million to 56 grantees, one each from the 50 states, 5 territories, and the District of Columbia, or their designees. Grantees are using this funding to support the efficient and creative use of broadband technology to better compete in the digital economy. These state-created efforts vary depending on local needs but include programs to assist small businesses and community institutions in using technology more effectively, research to investigate barriers to broadband adoption, innovative applications that increase access to government services and information, and state and local task forces to expand broadband access and adoption.

States are also using more than 50 percent of these grant funds to gather data twice a year on the availability, speed, and location of broadband services, as well as the broadband services that community institutions, such as schools, libraries and hospitals, use. This is the broadband data used to populate the National Broadband Map. Detailed descriptions of how this data was collected and processed can be found in the technical overview.

The data download page also contains several documents that provide context for this round of data, including a Changes and Corrections summary provided by each grantee, a data package per grantee that includes the list of providers contacted or included by each grantee. The zipped state file will also include each state's methodology.

Note on Broadband Dataset, Map, and Other Tools
Through the State Broadband Initiative, NTIA has assembled a comprehensive broadband dataset as well as a data review and validation process to ensure data integrity. The SBI data is an ongoing, collaborative data collection, review and revision process that involves the combined efforts of local, state and federal governments, broadband providers, private contractors, community anchor and academic institutions, and many community members across the country. Each grantee collects and verifies data twice per year before submitting it to NTIA. NTIA then reviews data, and if necessary, returns it to grantees for additional evaluation or corrections.

Notwithstanding the validation process, NTIA cannot guarantee the accuracy of all data. Furthermore, broadband deployment in the United States is continually changing and developing. Therefore, the biannual SBDD data release represents a best-efforts snapshot of the state of broadband deployment at a particular time. Following each release, NTIA welcomes and encourages input regarding the accuracy of the data and will use this feedback, together with the state grantees, to inform its iterative data improvement processes. Please explore the Engage section of the website to see all of the ways to participate in the National Broadband Map.
