Congressional and Legislative Districts

Following each decennial Census of the United States, Maryland, 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.

This site contains data and maps related to Maryland's Congressional and State Legislative districts adopted based on the 2000 decennial Census population counts. Maryland's existing Congressional districts are those adopted with the passage by the Maryland General Assembly of Senate Bill 805 - House Bill 1250 and its signing into law by the Governor, May 6, 2002. Maryland's existing Legislative districts are those ordered by the Maryland Court of Appeals on June 21, 2002 and as amended July 1, 2002.

The Department of Planning recently developed a series of online products to make accessing the 2002 Congressional and Legislative data and maps more accessible and convenient for viewing, printing, downloading and ordering.
