Demographic changes on the territory of Kruševac municipality in the second half of the 20th century are shown through the increase of the inhabitants in urban settlement as well as the drop of the number of inhabitants in rural settlements. Increase in the number of inhabitants leads to the increase of the number of households, as well as to the drop in the number of the members of those households. One of the most important problems is the ageing of population, ie, drop in the number of young population and significant rise in old population, so the population of Kruševac municipality is already in the phase of the deepest demographic old age. Such age structure influences further economic development of this area at large. Economic structure of the population sustained major changes in the period from 1991 to 2011, because many important industrial companies which were the carriers of economic development of this area were closed in that period.
