EVERY 10 YEARS --> A census is taken to determine the population in a state.
States that GAIN population get additional seats in the House of Representatives
States that LOSE population will lose sets in the House or Representatives
REAPPORTIONMENT basically means that the 435 seats in the house are divided up (reassigned, redistributed) based on the population.
If states GAIN or LOSE seats they will need to add new districts (draw new lines)
Gerrymandering is blatantly drawing district lines to favor one party over the other.
