image of Capitol HillMaryland, like all states, must draw new Congressional districts (U.S. Constitution Article I, Section 2) and State Legislative districts (Maryland Constitution Article III, Section 5) based on the principal of one-person one-vote following the decennial Census of the United States.

Maryland's current districts were adopted in 2002. The redistricting process began with the Census count in Spring 2010. It will continue with public hearings, review and analysis of proposed plans and eventual adoption of revised districts. They will be in place in time for the Congressional primary of 2012 and the State Legislative Election of 2014.

The Maryland Department of Planning (MDP) is the repository of Reapportionment and Redistricting maps and data products. MDP is Maryland's designated State Agency coordinator for the Census Redistricting Data Program with the U.S. Bureau of the Census.

Pursuant to Maryland law passed in 2010, the Maryland census data must be adjusted for purposes of creating congressional, state legislative, and local districting plans. Generally, the law requires that the census data must be adjusted to reassign Maryland residents in correctional institutions to their last known address and to exclude out-of-state residents in correctional institutions from redistricting. The State intends to post the adjusted data on the Internet this spring. For further information contact the Maryland Department of Planning at 410-767-4500 or the Maryland Department of Legislative Services at 410-946-5200 or 301-970-5200.
