Ky. Const. § 33

The first General Assembly after the adoption of this Constitution shall divide the State into thirty-eight Senatorial Districts, and one hundred Representative Districts, as nearly equal in population as may be without dividing any county, except where a county may include more than one district, which districts shall constitute the Senatorial and Representative Districts for ten years. Not more than two counties shall be joined together to form a Representative District: Provided, In doing so the principle requiring every district to be as nearly equal in population as may be shall not be violated. At the expiration of that time, the General Assembly shall then, and every ten years thereafter, redistrict the State according to this rule, and for the purposes expressed in this section. If, in making said districts, inequality of population should be unavoidable, any advantage resulting therefrom shall be given to districts having the largest territory. No part of a county shall be added to another county to make a district, and the counties forming a district shall be contiguous.
