Title: Smart Location Database
Abstract: A large body of research has demonstrated that land use and urban form can have a significant effect on transportation outcomes. People who live and/or work in compact neighborhoods with a walkable street grid and easy access to public transit, jobs, stores, and services are more likely to have several transportation options to meet their everyday needs. As a result, they can choose to drive less, which reduces their emissions of greenhouse gases and other pollutants compared to people who live and work in places that are not location efficient. Walking, biking, and taking public transit can also save people money and improve their health by encouraging physical activity. The Smart Location Database summarizes several demographic, employment, and built environment variables for every census block group (CBG) in the United States. The database includes indicators of the commonly cited ā€œDā€ variables shown in the transportation research literature to be related to travel behavior. The Ds include residential and employment density, land use diversity, design of the built environment, access to destinations, and distance to transit. SLD variables can be used as inputs to travel demand models, baseline data for scenario planning studies, and combined into composite indicators characterizing the relative location efficiency of CBG within U.S. metropolitan regions. This update features the most recent geographic boundaries (2019 Census Block Groups) and new and expanded sources of data used to calculate variables. Entirely new variables have been added and the methods used to calculate some of the SLD variables have changed.

Use: These data are available for public access and use and carry no restrictions. See the Smart Location Database Technical Documentation and User Guide (2021) for data sources (https://www.epa.gov/smartgrowth/smart-location-database-technical-documentation-and-user-guide), limitations, and methodologies used to calculate the variables in the Smart Location Database. Although the majority of SLD variables are consistent in the data source and calculation method to previous versions, it may not be appropriate to compare all variables with version 2.0 directly. Changes in data sources and methods are explained in detail in this guide. See the National Walkability Index User Guide and Methodology and or email SLC@gsa.gov for more information on the data and methodology of the Smart Location Calculator.
