This date was January 6, 2009, which was two weeks before the beginning of the first administrative year of Democratic Governor Jack Markell from New Castle County and Democratic Lieutenant Governor Matthew Denn, also from New Castle County.

Currently the distribution of seats for both houses was based on the interpretation of the federal 2000 census.

It resulted from a large number of memberships in the New Castle County area and ruling that the election districts would abandon county lines for their boundaries, but would design whatever district boundaries that would accomplish such population equals.

They were designed for equal populations from all districts and its accomplishment occasionally included some territory from two counties.
