As part of the Home Rule Cities Act, a provision was made for the incorporation of fifth class cities. The provision was added to allow for villages that weren't large enough under the provisions of the main act to become home rule cities. The only difference between a fifth-class city and a regular home rule city was that settlements only had to have a population between 750 and 2,000 with a density of 500 people per square mile - though the density requirement was waived for settlements which had already incorporated as villages - and that all elected officials had to be elected at-large. No fifth class cities currently exist.
