Data Updates

Data displayed on the National Broadband Map site are as of June 30, 2014 and are no longer being updated. The Commission sought funding for FY 2016 to maintain and update the National Broadband Map, but this request was not granted.

While the Commission is not currently in a position to update the map in light of funding constraints, it continues to collect and report on deployment through its semi-annual Form 477 data collection and
annual Broadband Progress Report.

Beginning with data as of December 2014, data are available for download on the FCC website. Future rounds of data will also be posted at the same link.


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. First published in February 2011, the NBM was updated every six months through April 2015 with data from the State Broadband Initiative. 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. Broadband deployment data is now collected biannually from service providers by the FCC through the Form 477 Data Program.

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 worked to accomplish this goal by providing grants. NTIA 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 used this funding to support the efficient and creative use of broadband technology to better compete in the digital economy. These state-created efforts varied depending on local needs, but included programs that assisted small businesses and community institutions in using technology more effectively, research that investigated barriers to broadband adoption, innovative applications that increased access to government services and information, and state and local task forces that expanded broadband access and adoption.

States used 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 for community institutions, such as schools, libraries and hospitals. That data was used to populate the National Broadband Map through June 2014, the most recent edition of the 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 the final round of data, including a Changes and Corrections summary provided by each grantee and 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 assembled a comprehensive broadband dataset, as well as a data review and validation process to ensure data integrity. The SBI data was a collaborative data collection, review, and revision process. It involved 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 collected and verified data twice per year before submitting it to NTIA. NTIA then reviewed data, and, if necessary, returned 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 SBDD data represents a best-efforts snapshot of the state of broadband deployment as of the last release (June 30, 2014).

With the completion of the SBI program, the FCC assumed responsibility for collecting broadband deployment data through the Order Modernizing the FCC Form 477 Data Program. More recent data can be found on the FCC website. Please explore the FAQ section of the website for more information about the National Broadband Map and current data collection procedures.
