Final answer:
Women, racial/ethnic minorities, and younger voters are the most underrepresented in terms of their candidacies relative to population, while White men and older population are the most overrepresented.
Step-by-step explanation:
When considering the representation of different demographic groups in terms of their candidacies relative to population, we can arrange them from most underrepresented to most overrepresented. Based on the information provided, groups that have traditionally been underrepresented in terms of their candidacies relative to population include women, racial/ethnic minorities, and younger voters. In contrast, groups that have been overrepresented include White men and older population. These imbalances in representation can be influenced by factors such as shared experiences, concerns, and ideas among certain groups.
