Image that the last U.S. census indicated that there is a major shift in our population where the northwest states are decreasing in population and the southwest states are increasing in population by more than 3 million. Discuss how this might affect the apportionment of the representation in House of Representative. Solution This seems ot be more of a US Government question rather than math. The apportionment of representatives in the Norwest in the House would decrease because of lowering populations, while representatives in the Southwest would increase because of growing population. According to Wikipedia there are about 700,000 people in a population per representative. If 700,000 people left a certain state in the Northwest, then it would lose a representative. If 700,000 came into a Southwest state, then it would gain a representative. .
