Redistricting is the process of drawing new electoral district
lines in order to equalize populations
Why do we Redistrict?
In the 1960s, the Supreme Court ruled that population imbalances among electoral districts were a violation of the US Constitution’s equal protection clause. They affirmed that votes of people living in more populated districts were, in fact, worth less than votes of citizens living in less populated districts. The court therefore required states to start maintaining roughly the same number of people in each district so that each person’s vote is worth nearly the same amount
States abide by the courts ruling via the census.
Every ten years, the census bureau conducts a count of all persons living in the United States. Based on those numbers, states are able to draw new lines so that each district has approximately the same number of people.
