The supervisor districts may be changed after each state and federal census if it appears from an examination that the population has become unequal among the several districts. In the event of any change or amendment of sections 23-201 to 23-299 which may necessitate a change in the boundaries of such supervisor districts or any one of them, the county board shall make such change in boundary at its next regular meeting after such change or amendment takes effect. Those counties under township organization may change their procedures for electing members to their governing board from district to at large or from at large to district following the provisions of section 32-554.
