Congressional & Le​gislative Districts
Maryland adopted new Congressional districts on October 20. 2011 (per U.S. Constitution Article I, Section 2) and new State Legislative districts on February 24, 2012 (per Maryland Constitution Article III, Section 5) based on the changes in population reported in the 2010 U.S. Census and in accordance with Maryland’s “No Representation Without Population Act” of 2010.

The Maryland Department of Planning (MDP) is the repository of the 2011 Congressional and 2012 Legislative districts as well as historical reapportionment and redistricting maps and data. MDP is Maryland's designated State Agency coordinator for the Census Redistricting Data Program with the U.S. Bureau of the Census.​

*We are not able to process requests for paper maps at this time. We can only fulfill requests for digital maps.

On February 12th, the USCB released an announcementthat the data used for redistricting will be distributed to the states “by September 30th.” Once the data is received, it must be adjusted in compliance with Maryland law to have incarcerated individuals reallocated to their last known address. This is required at the local and municipal level as well as the congressional and state level. We are prepared to have that process begin as soon as we receive the data and estimate that it may take at least an additional 30 days to accomplish completion of this task before final data is available.
We are able to provide Maryland Congressional and Legislative District related maps upon request. Electronic PDF copies can be emailed free of charge. Paper copies are printed at 36"x48" and are $25 for black and white and $50 for color. Please use the following form to request a Congressional or Legislative District Map.
