Demographic changes influence political representation by altering the electorate's composition, which can affect voting patterns and policy priorities. Factors such as age, race, and gender can shift the priorities of political parties and result in different candidates gaining traction. For instance, growing populations of minority groups can lead to increased advocacy for diversity and inclusion in governance. As demographic shifts occur, they challenge traditional political structures, urging lawmakers to address the evolving needs and concerns of an increasingly diverse society, thus enhancing political engagement and representation.
