Which of the following plays a significant role in the shifting of both voting patterns and district boundaries? a. political issues b. tax codes c. population d. income

C. population

Explanation:

Both voting patterns and district boundaries can be affected by population changes. Voting patterns change when changes in population occur. For example, large urban centers or cities with a high level of immigration tend to become more liberal than rural, uniform places. On the other hand, district boundaries also change with changes in population because population size is one of the main factors that determine how districts are drawn.
