9-2-2. Population determined by census--Estimate by election totals after change of municipal boundaries.
For the purpose of classification the population of each municipality shall be determined by the last preceding federal census. Whenever the enumeration of such last preceding census was made with reference to territory substantially different from that embraced by the boundaries of the municipality, the governing body by resolution may authorize and direct its auditor or clerk to determine the population by filing in his office a certificate showing the whole number of persons who voted at the last preceding annual municipal election, which number multiplied by three shall constitute the population for the purpose of classification until the next federal census shall have been completed.
