Redistricting is the process of redrawing the boundaries of electoral districts, which are used for electing representatives in government. This usually occurs every ten years after the U.S. Census, which counts the population and helps ensure that districts have roughly equal numbers of residents. The goal of redistricting is to reflect changes in population and demographics, ensuring fair representation. However, it can also lead to controversies, such as gerrymandering, where district lines are manipulated to favor one political party over another, potentially undermining the principle of fair elections.
