The Regional Data Catalog is a repository of open data managed by the Denver Regional Council of Governments. The datasets in this catalog support communities in making informed, data-driven decisions in areas including mobility, land use, and changing demographics.


DRCOG develops and compiles data that we source from local governments, data companies, our land use and travel models, and data acquisition projects that we facilitate. We focus on topic areas that we are uniquely suited to address such as regional forecasts, transportation projects, and planimetric data.

The data in the catalog is regional in scale and may be updated less frequently than authoritative local sources. Access to local data is provided through the following open data sites: Adams County, Arapahoe County, Arvada, Aurora, Boulder, Boulder County, Brighton, Broomfield, Castle Rock, Centennial, Commerce City, Denver, Douglas County, Erie, Frederick, Jefferson County, Lone Tree, Longmont, Parker, Thornton, and Weld County.


DRCOG relies on our partners in the region to provide data and analysis that is complementary to our offerings. We encourage you to check their sites for anything you did not find on ours.
