2002-2021 Districts
Every 10 years, districts for members of Congress, the State House of Representatives, the State Senate, and the Governor’s Council are re-drawn by the Legislature. This process happens after each federal census in order to make sure each district is made up of approximately the same number of people.
Established by the Acts of 2011, Chapter 152.
