Research & Data

NDIA conducts, supports, and promotes data-gathering and research to inform public understanding, policy, and community strategies that advance digital equity.
Prioritizing Research-Based Strategies
NDIA Research and Tools

NDIA is committed to bridging the digital divide and ensuring everyone can thrive in today’s digital world, recognizing that effective solutions require a deep understanding of present issues. Our approaches are grounded in comprehensive research and innovative strategies that address the multifaceted challenges of digital equity, and we believe the best strategies come from the communities we support. We actively engage with local and national organizations, practitioners, and community leaders to co-create interventions, identify specific challenges, and inform the development of programs that enhance access to affordable internet and essential resources.

Primary Data Sources

American Community Survey (ACS)

The American Community Survey (ACS) is the US Census’ annual large-scale survey of US households for all kinds of social, demographic, economic, and housing information. The survey includes several questions about digital devices and internet access going back to 2013. It is the most frequently used datasource for residential broadband adoption and device adoption. It also incorporates some high-level information about types of internet service and devices. The ACS data is aggregated for numerous geographic levels ranging from the entire nation and whole states down to Census tracts and block groups.

ACS data is published each year in two primary datasets:

  • The ACS 1-Year Estimates, which include only data gathered a given year and report details only for geographic entities with 65,000 or more residents;  and
  • the ACS 5-Year Estimates, which provide statistically combined data over a five-year period for a much wider range of geographies including Census block groups, tracts, and lower-population towns and counties.
ACS Tables Relevant to Digital Inclusion

The digital inclusion data in the ACS are reported in the following tables:

Types of Computers in Household

Presence and Types of Internet Subscriptions in Household

Presence of a Computer and Type of Internet Subscription in Household

Household Income in the Last 12 Months by Presence and Type of Internet Subscription in Household

Age by Presence of a Computer and Types of Internet Subscription in Household

Educational Attainment by Presence of a Computer and Types of Internet Subscription in Household

Labor Force Status by Presence of a Computer and Types of Internet Subscription in Household

Presence of a Computer and Type of Internet Subscription in Household

Presence of a Computer and Type of Internet Subscription in Household by Race/Ethnicity

Current Population Survey (CPS): Computer and Internet Use Supplement

The CPS Computer and Internet Use Supplement is a partnership of NTIA, the Bureau of Labor Statistics, and the US Census Bureau to measure household internet and digital device access and usage. It also includes information on where, how, and for what purposes people use the computers and the internet, along with perceptions and concerns related to internet usage. This makes it the only national-scale public dataset with information on people’s online behaviors and attitudes. In the absence of an authoritative source for digital skills data, the user behavior and perception data is used to infer digital skills needs. For example, disparities in the use of the internet for certain purposes (e.g. job searching, accessing health records, or making online purchases), concerns with internet usage (e.g. identity theft or online harassment), and reasons for not having home internet can be used as heuristics for digital skills.

CPS Computer and Internet Use Supplement data is available for every other year between 2013 and 2021. The Census Bureau’s Microdata Access Tool allows you to aggregate data at the state and county level. You can also download the entire dataset, however it requires significant formatting to be usable.

Broadband Data Collection and National Broadband Map

The Federal Communications Commission’s (FCC) National Broadband Map is the definitive source of data on broadband availability in the US States and Territories. The most notable difference between the National Broadband Map and the FCC’s previous method of assessing broadband availability, Form 477, is that the new map’s lowest level of geography is a “broadband serviceable location” (BSL), such as one house or office-building, rather than census blocks. For each BSL, the dataset tracks the Internet Service Provider’s (ISP) name, the type of internet technology, the speed, whether the location is a residence or business, and the number of units if it is a multiple dwelling unit. The FCC first released the National Broadband Map in November 2022 and will update it every six months to reflect feedback and updates from ISPs and community challenges to the map. It is important to note that the National Broadband Map only shows availability, i.e. a location that is able to be serviced, and whether or not it is currently serviced. It does not reflect the quality or affordability of the internet connection.

 

From the site, you can download data by state or by provider. After selecting a state or provider, you can download data summarizing all types of fixed broadband technologies or mobile broadband technologies, or you can choose one specific type of technology (for instance, “Fiber to the Premises”). The data comes in a CSV format and downloads in a ZIP file. Note that the data download provides a location code and the census block it is in, rather than individual addresses.

Affordable Connectivity Program (ACP), Lifeline, and Other Subsidy Data

Data about participation in broadband subsidy programs are valuable for understanding the extent to which existing broadband affordability resources are being leveraged, and where greater outreach and engagement may be needed. The Universal Service Administrative Company (USAC) administers ACP, Universal Service Fund programs (E-Rate, High-Cost, Lifeline, and Rural Health Care), and Emergency Connectivity Fund (ECF). As part of its administrative role, USAC collects and publishes data about these programs through its Open Data Portal. USAC publishes ACP program data separately on the ACP Enrollment & Claims Tracker.

Data on USAC programs vary in detail, granularity, and update schedule by program. For the two household-level broadband subsidy programs, the following is available:

  • Lifeline – County-level subscriber counts by service type and state-level total subscribers vs. eligible households
  • ACP – Zip code, county, and state-level enrollment and claims data, with details such as breakdown by verification method, subscription and device claims, and funding awarded.

Dashboards, Tools, and Visualizations
  • Pew Internet Research: The longest-running consistent source of rich national survey information on Americans’ attitudes and practices on digital topics, including adoption and use of computing devices and the internet.
  • Institute for Local Self Reliance ACP Dashboard: Allows users to see ACP enrollment by state and Congressional district, highest and lowest enrolled cities, and the amount of federal ACP funding left.
  • Benton Institute Affordable Connectivity Program Enrollment Performance Tool: This tool classifies zip code areas into five categories based on the difference between actual ACP enrollment and predicted enrollment. High performing zip code areas are those where actual enrollment exceeds predicted levels, while low performing areas have fewer ACP households enrolled than what the tool’s statistical model predicts.
  • Digital Progress ACP Map: This map shows ACP enrollment out of the total number of households in each State and Congressional District.
  • EducationSuperHighway ACP Enrollment Dashboard: This dashboard shows a map of the United States, comparing eligibility and actual enrollment per state. It also highlights states with a governor who has made ACP a priority
