Synopsis: K.S.A. 15-101, K.S.A. 14-101, and K.S.A. 13-101 do not provide for reclassifying a city based on a decrease in population. But K.S.A. 14-901 does allow for a city of the second class to be reclassified as a city of the third class if the population falls to 1,000 or less and a majority of voters approve of the reclassification. There is no similar mechanism for reclassifying a city of the first class to a city of the second class.
