Updated Urban Sprawl Data for the United States
The report and Excel files below contain methods and data concerning revised and updated urban sprawl indices. These indices, developed by Dr. Reid Ewing and his team at the University of Utah, are freely available for download.
- Measuring Urban Sprawl and Validating Sprawl Measures (PDF - 4.03 MB)
This file contains a report describing the development and analysis of the updated sprawl indices and Ewing's earlier sprawl index developed with 2000 Census data.
- Appendix A of the report contains county compactness indices for 2010, 2000, and changes in the new and original indices.
- Appendix B of the report contains county compactness factors and composite indices for 2010.
- Appendix C of the report contains 2010 metropolitan Indices.
- Appendix D of the report contains 2010 urbanized areas compactness indices.
- Appendix E of the report contains 2000 urbanized areas compactness indices.
- For convenience, these data and additional tabulations, organized into separate Excel files by census tract, urbanized areas, MSA's, and county are also available.
Better data describing changes in urban form over time has the potential to strengthen evidence for the role of the built environment in access to health services and as an influence on energy balance behaviors. More information about this work and about Urban Sprawl are also available at http://www.smartgrowthamerica.org. We encourage interested parties do download and analyze these data.
