Project Description

Summary: This dataset contains measures of broadband internet access and usage per United States ZIP code tabulation area (ZCTA) in 2014 through 2018. The data is derived primarily from internet service providers’ Form 477 reports to the Federal Communications Commission. Key variables include the average upload and download speed of fixed broadband connections, the number of internet service providers, and the number of households with broadband.

Funding Sources: United States Department of Health and Human Services. Administration for Community Living. National Institute on Disability, Independent Living, and Rehabilitation Research (90RTHF0001); United States Department of Health and Human Services. National Institutes of Health. National Institute on Aging (RF1-AG-057540)

Scope of Project

Subject Terms: internet access; broadband; access to information

Geographic Coverage: United States

Time Period(s): 2014 – 2018

Collection Date(s): 2020 – 2020

Universe: ZCTAs in the United States, island territories, and possessions.

Data Type(s): aggregate data

Collection Notes: A ZIP code to ZCTA crosswalk must be used to combine this dataset with ZIP code geocoded data must use a ZIP code to ZCTA crosswalk. Such a crosswalk is available on the UDS Mapper website at https://udsmapper.org/zip-code-to-zcta-crosswalk/. Sample code for merging the UDS Mapper crosswalk with NaNDA datasets is available on the NaNDA repository at https://www.openicpsr.org/openicpsr/project/120088/.

Methodology

Data Source: Data on broadband connection speed is taken from the FCC’s Broadband Deployment Data reports from December 2014-December 2018. Data on the number of residential fixed-speed connections comes from the American Community Survey 2017 five-year estimate.

Unit(s) of Observation: ZIP code tabulation area, year
