With respect to the distribution of funds to the counties, the computations for distribution must be made by the state agency responsible for collecting the same as follows:
(1) The share coming to each eligible county must be determined by a division among the eligible counties according to the relation which the population of the unincorporated area of such eligible county, as last determined by the office of financial management, bears to the population of the total combined unincorporated areas of all eligible counties, as determined by the office of financial management. However, no county in which the sale of liquor is forbidden in the unincorporated area thereof as the result of an election is entitled to share in such distribution. "Unincorporated area" means all that portion of any county not included within the limits of incorporated cities and towns.
(2) When a special county census has been conducted for the purpose of determining the population base of a county's unincorporated area for use in the distribution of liquor funds, the census figure becomes effective for the purpose of distributing funds as of the official census date once the census results have been certified by the office of financial management and officially submitted to the office of the secretary of state.
