(55 ILCS 5/2-3002) (from Ch. 34, par. 2-3002)
    Sec. 2-3002. Counties with population of less than 3,000,000 and with township form of government.
    (a) Reapportionment required. By July 1, 1971, and each 10 years thereafter, the county board of each county having a population of less than 3,000,000 inhabitants and the township form of government shall reapportion its county so that each member of the county board represents the same number of inhabitants, except that, for the reapportionment of 2021, the county board shall reapportion its county by December 31, 2021. In reapportioning its county, the county board shall first determine the size of the county board to be elected, which may consist of not less than 5 nor more than 29 members and may not exceed the size of the county board in that county on October 2, 1969. The county board shall also determine whether board members shall be elected at large from the county or by county board districts.
    If the chairman of the county board is to be elected by the voters in a county of less than 450,000 population as provided in Section 2-3007, such chairman shall not be counted as a member of the county board for the purpose of the limitations on the size of a county board provided in this Section.
    (b) Advisory referenda. The voters of a county may advise the county board, through an advisory referendum, on questions concerning (i) the number of members of the county board to be elected, (ii) whether the board members should be elected from single-member districts, multi-member districts, or at-large, (iii) whether voters will have cumulative voting rights in the election of county board members, or (iv) any combination of the preceding 3 questions. The advisory referendum may be initiated either by petition or by ordinance of the county board. A written petition for an advisory referendum authorized by this Section must contain the signatures of at least 8% of the votes cast for candidates for Governor in the preceding gubernatorial election by the registered voters of the county and must be filed with the appropriate election authority. An ordinance initiating an advisory referendum authorized by this Section must be approved by a majority of the members of the county board and must be filed with the appropriate election authority. An advisory referendum initiated under this Section shall be placed on the ballot at the general election designated in the petition or ordinance.
