title: National Neighborhood Data Archive (NaNDA): Public Transit Stops by Census Tract and ZIP Code Tabulation Area, United States, 2016-2018 and 2024
title: Archival Version

description: This study includes the number of public transit stops per United States census tract or ZIP code tabulation area (ZCTA) based on data from the National Transit Map (NTM). Each observation represents the count and density (per capita and square mile) of transit stops within a census tract or ZIP code tabulation area (ZCTA), as voluntarily reported to NTM between 2016-2018 and 2024 by one of 270 regional transit agencies choosing to participate.
description: The purpose this study is to measure the number of public transit stops per United States census tract or ZIP code tabulation area (ZCTA) based on data from the National Transit Map (NTM).
description: The research team utilized National Transit Map (NTM) data to construct each observation. Each observation represents the count and density of transit stops within a census tract or ZIP code tabulation area. Density is measured both by population density (per 1000 people) and distance (per square mile).
The 2016-2018 public transit data were voluntarily reported to the NTM by regional transit authorities, resulting in a fair amount of missing data. Beginning in Report Year 2023, the Federal Transit Administration (FTA) began requiring National Transit Database (NTD) Reporters to report and submit General Transit Feed Specification (GTFS) data for their fixed route service to the NTM (Bureau of Transportation Statistics).
Public Transit Stop counts were aggregated by researchers to the census tract and ZCTA areas.
description: Variables include count of transit stops reported to National Transit Map between 2016-2018 and in 2024, transit stops per 1000 people, transit stops per square mile, total population counts via Census tract and ZIP code tabulation area measures.

National Neighborhood Data Archive (NaNDA): Public Transit Stops by Census Tract, United States, 2016-2018 and 
National Neighborhood Data Archive (NaNDA): Public Transit Stops by ZIP Code Tabulation Area, United States, 2016-2018 were originally deposited in openICPSR.
The 2024 data were not included in these original deposits.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.For additional information see
