description: These datasets contain measures of internet access per United States census tract and ZIP code tabulation area (ZCTA) from the 2015-2019 American Community Survey five-year estimate. Key variables include the number and percent of households per tract or ZCTA with any type of internet subscription, with broadband internet, and with a computer or smartphone.

description: To create the datasets, the research team selected variables related to internet adoption and internet-enabled devices from the American Community Survey:
Table B28002, Presence and Types of Internet Subscriptions in Household

B28002e2, households with broadband of any type:

B28002e4, households with broadband of any type (DSL/fiber/cable, satellite, or cellular); 
B28002e7, households with DSL/fiber/cable broadband;
B28002e9, households with satellite broadband;
B28002e5, households with cellular broadband


B28002e12, households with internet access but no subscription (e.g., city- or university-provided free internet)
B28002e13, households with no internet access

Tables B28010, Computers in Household, and B28003, Presence of a Computer and Type of Internet Subscription in Household

B28003e4, households with any kind of computing device and a broadband subscription (DSL/fiber/cable, satellite, or cellular)
B28010e2, households with any kind of computing device:

B28010e3, households with a desktop or laptop (but not only a desktop or laptop);
B28010e5, households with a smartphone, tablet, or other device (but not only a smartphone/tablet)


B28010e7, households with no computing device
The hierarchical relationship of variables within these tables shows how the variables relate to each other. For example, B28010e3 and B28010e5 are subsets of B28010e2.
The researchers divided each of these values by the total number of households in the tract or zip code tabulation area to create proportions.

DS0: Study-Level Files
DS1: Internet Access by Census Tract Data
DS2: Internet Access by ZIP Code Tabulation Area Data
description: Census tracts and ZIP code tabulation areas in the United States, including Puerto Rico. Smallest Geographic Unit: Census tract
description: The data and documentation for the Internet Access by Census Tract Data were originally deposited in openICPSR 155022.
The data and documentation for the Internet Access by ZIP Code Tabulation Area Data were originally deposited in openICPSR 155025.A ZIP code to ZCTA crosswalk must be used to combine the ZCTA dataset with ZIP code geocoded data. A crosswalk and sample code for merging the crosswalk with National Neighborhood Data Archive (NaNDA) datasets are available in the ICPSR Linkage Library.These datasets supplement the following projects available through openICPSR:
National Neighborhood Data Archive (NaNDA): Broadband Internet Availability, Speed, and Adoption by Census Tract, United States, 2014-2020
National Neighborhood Data Archive (NaNDA): Broadband Internet Availability and Speed by ZIP Code Tabulation Area, United States, 2014-2020For additional information, see the National Neighborhood Data Archive (NaNDA).
