Maps & District Boundaries
One residence can belong to several electoral maps. Start with the right layer.
Choose the map for your question.
Congressional districts
Each of Colorado’s eight districts elects one U.S. representative.
State House and Senate
Separate maps identify your state representative and senator.
County and city boundaries
Use county and incorporated-place layers in the Census boundary viewer. A census-designated place is not necessarily a city government.
School and special districts
Confirm district boundaries, board members and election rules through official district records and your county clerk.
Check the map’s effective date. TIGERweb’s “Current” congressional layer may cover the next Congress; this guide’s serving-member references use the 119th Congress.
