Other Data Resources

Some of the data our residents need is published by other agencies. These are the portals and clearinghouses we rely on and recommend — statewide, regional, and federal sources that go beyond what Montgomery County publishes directly.

Note: These are external sites, maintained by their own agencies. Montgomery County doesn't control their content or availability. Looking for county data? Browse our own catalog on the Datasets page.

Links to external sites are provided for convenience and reference. Montgomery County GIS & Mapping Services does not maintain these resources and cannot guarantee the accuracy, completeness, or availability of data hosted elsewhere.
