Redistricting is the process of redrawing electoral district boundaries, usually every ten years after the census, to account for population changes. In AP Gov, it links congressional behavior (2.3), equal protection challenges (3.12), and congressional elections (5.9).
Redistricting is the redrawing of the boundary lines for congressional and state legislative districts. It happens after every national census, which counts the population every ten years and triggers reapportionment (states gaining or losing House seats based on population shifts). Once a state knows how many seats it has, someone has to draw the map, and in most states that someone is the state legislature.
That's where the politics come in. Whoever controls the map controls a lot. Lines can be drawn to pack opponents into a few districts, spread them thin across many, protect incumbents, or create majority-minority districts. The CED frames redistricting as one of the structural forces shaping congressional behavior, because a member elected from a safely drawn district has little incentive to compromise. The Supreme Court has stepped in repeatedly, starting with Baker v. Carr (1962), which opened the door for equal protection challenges to unfair district maps.
Redistricting is one of the rare terms that shows up in three separate units. In Unit 2, learning objective 2.3.A asks you to explain how election processes influence congressional behavior, and the essential knowledge specifically names gerrymandering, redistricting, and unequal representation as problems the Supreme Court has partially addressed through equal protection challenges. In Unit 3, Topic 3.12 covers how the Court has both protected and limited minority rights in cases about majority-minority districting. In Unit 5, Topic 5.9 connects redistricting to congressional election outcomes, especially the incumbency advantage, since safely drawn districts are a big reason incumbents almost never lose. If you understand redistricting, you have a thread that ties Congress, civil rights, and elections together.

Gerrymandering (Units 2 & 5)
Redistricting is the process; gerrymandering is the abuse of it. Every state redistricts after the census, but gerrymandering happens when the lines are drawn deliberately to favor one party or group. The CED pairs them in Topic 2.3 because gerrymandered districts produce more ideologically extreme members of Congress, which feeds polarization and gridlock.
Baker v. Carr (Unit 2)
Before 1962, federal courts refused to touch redistricting, calling it a political question. Baker v. Carr changed that, ruling that voters could bring equal protection challenges to unfair district maps. This is the case that made every later redistricting fight, including racial gerrymandering cases, possible. It's a required SCOTUS case, so know it cold.
Majority-Minority Districts (Unit 3)
Some districts are drawn so a racial minority makes up the majority of voters, boosting minority representation in Congress. Topic 3.12 covers the tension here. The Court has at times upheld majority rights in ways that limit race-based districting, ruling that race cannot be the predominant factor in drawing lines. Cooper v. Harris (2017) struck down North Carolina districts on exactly these grounds.
Census (Units 2 & 5)
The census is the trigger for the whole cycle. The count happens every ten years, House seats get reapportioned among the states, and then states redraw their maps. No census, no redistricting. The 2015 SAQ on Bush v. Vera started with exactly this setup, with Texas gaining three congressional districts after the 1990 census.
Redistricting shows up across question types. Multiple-choice questions test whether you know what Baker v. Carr established (federal courts can hear redistricting challenges under equal protection) and how the Court has handled race in districting, like the Cooper v. Harris (2017) ruling that North Carolina improperly used race in its maps. It also appears in stems about polarization and gridlock, since gerrymandered safe seats are a standard explanation for why congressional voting has become more partisan. On the free-response side, the 2015 SAQ used Bush v. Vera (1996), where Texas redrew its borders after gaining three districts from the 1990 census. The SCOTUS comparison FRQ is a prime spot for Baker v. Carr or Shaw v. Reno, so be ready to connect a nonrequired redistricting case back to a required one using the equal protection clause as the bridge.
Redistricting is neutral and required. District lines have to be redrawn after each census because populations shift. Gerrymandering is what happens when the people drawing those lines manipulate them for political advantage, by packing the other party's voters into one district or cracking them across several. On the exam, if a question describes redrawing lines to benefit a party or to dilute a group's votes, the answer is gerrymandering. If it just describes redrawing lines after the census, that's redistricting.
Redistricting is the redrawing of electoral district boundaries every ten years after the census, after House seats are reapportioned among the states.
In most states the state legislature draws the new maps, which is why the party in power can gerrymander districts to its advantage.
Baker v. Carr (1962) opened federal courts to equal protection challenges against unfair district maps, ending the era when redistricting was treated as a purely political question.
The Supreme Court has limited race-based districting, ruling in cases like Cooper v. Harris (2017) that race cannot be the predominant factor in drawing district lines.
Redistricting helps explain the incumbency advantage and partisan gridlock, because members from safely drawn districts face little pressure to compromise.
Redistricting is the process of redrawing congressional and state legislative district boundaries to reflect population changes, done every ten years after the national census. It appears in Topics 2.3, 3.12, and 5.9 of the CED.
No. Redistricting is the required, neutral process of redrawing lines after the census. Gerrymandering is the manipulation of that process to benefit a party or group. All gerrymandering happens through redistricting, but not all redistricting is gerrymandering.
No. Redistricting normally happens once per decade, after the census triggers reapportionment of House seats. The same maps are then used for the elections that follow until the next census, unless a court strikes them down.
Baker v. Carr (1962) ruled that federal courts can hear challenges to district maps under the equal protection clause, rejecting the old view that redistricting was a political question courts couldn't touch. It's one of the required Supreme Court cases for the AP Gov exam.
Only in a limited way. The Court has struck down maps where race was the predominant factor, as in Cooper v. Harris (2017) against North Carolina. Topic 3.12 frames this as the Court sometimes upholding majority rights by limiting majority-minority districting.
