Redistricting

Gerrymandering: This is when political parties manipulate district boundaries to favor their party. It's like if the popular kids at school got to decide who sat at which tables, they'd probably arrange things so their friends had more seats.

Census: A count of all people living in a country, state or city. It's like taking attendance at school - it helps determine how many seats (or districts) are needed.

Apportionment: The process by which seats in a legislative body are distributed among administrative divisions entitled to representation. It's like deciding how many tables (or districts) there should be based on how many students (or population) there are.
