(2) The whole population of the state, as determined by the federal decennial census or, if the federal decennial census is unavailable, another basis as directed by the general assembly, shall be divided by the number of congressional districts apportioned to the state pursuant to Section 2 of Article I of the Constitution of the United States, and the quotient shall be the congressional ratio of representation for the next ten years.
(3) Notwithstanding the fact that boundaries of counties, municipal corporations, and townships within a district may be changed, district boundaries shall be created by using the data from the most recent federal decennial census or from the basis directed by the general assembly, as applicable.
(2) Every congressional district shall be compact.
(3) Every congressional district shall be composed of contiguous territory, and the boundary of each district shall be a single nonintersecting continuous line.
(4) Except as otherwise required by federal law, in a county that contains a population that exceeds the congressional ratio of representation, the authority drawing the districts shall take the first of the following actions that applies to that county:
(b) If one municipal corporation or township in that county contains a population of not less than one hundred thousand and not more than the congressional ratio of representation, that municipal corporation or township shall not be split. If that county contains two or more such municipal corporations or townships, only the most populous of those municipal corporations or townships shall not be split.
(6) If a congressional district includes only part of the territory of a particular county, the part of that congressional district that lies in that particular county shall be contiguous within the boundaries of the county.
(7) No two congressional districts shall share portions of the territory of more than one county, except for a county whose population exceeds four hundred thousand.
(8) The authority drawing the districts shall attempt to include at least one whole county in each congressional district. This division does not apply to a congressional district that is contained entirely within one county or that cannot be drawn in that manner while complying with federal law.
(2) If a municipal corporation or township has territory in more than one county, the contiguous portion of that municipal corporation or township that lies in each county shall be considered to be a separate municipal corporation or township for purposes of this section.
