Census Data for Transportation Applications

Posted: 10/31/2025

NCHRP's Census Data Field Guide for Transportation Applications presents a comprehensive field guide for transportation practitioners on how to effectively utilize census data to support transportation analyses.

The Census Transportation Planning Products datasets and the American Community Survey are critical data elements that support the analysis of transportation plans, policies, programs, and project selection. Changes in the data products over the last 10 years and ongoing staff turnover have left a void of expertise in effectively using these data to support transportation planning. Additionally, there is no centralized resource location where one can go to learn how to use the data for real world applications. This results in wasted time and questionable analysis.

The field guide is based on scenarios that illustrate various uses of census data to address transportation issues. It will be of immediate interest to transportation planners, metropolitan planning organizations, and transit operators.
