Frequently Asked Questions
What is the main purpose of congressional districts?
Congressional districts divide states into electoral regions, each represented by one member in the U.S. House of Representatives. Their main purpose is to ensure proportional representation based on population.
How does the U.S. Census impact congressional districts?
The decennial U.S. Census provides the population data used for reapportionment (determining the number of House seats each state gets) and redistricting (redrawing the boundaries of those districts within states).
What is gerrymandering and why is it controversial?
Gerrymandering is the manipulation of electoral district boundaries to create an unfair advantage for a political party or group. It’s controversial because it can distort voter intent, reduce competitiveness, and entrench incumbents, undermining fair democratic representation.
Who is responsible for drawing congressional district lines?
In most states, the state legislature is responsible for drawing congressional district lines. However, some states use independent or bipartisan commissions to reduce political influence in the process.
What does the “one person, one vote” principle mean in redistricting?
The “one person, one vote” principle, established by the U.S. Supreme Court, mandates that electoral districts within a state must contain roughly equal populations. This ensures that each citizen’s vote carries approximately the same weight, regardless of where they live.
