Redistricting was not declared unconstitutional in the 1963 case Gray v. Sanders. It was after that.
Redistricting is always controlled by the state legislature following the census. It is approved by the governor and/or by the redistricting commissions in states such as Arizona and Iowa.
How often must legislative redistricting be done in Illinois?
Redistricting occurs every ten years, with the national census.
Reapportionment, which happens every ten years when there is a census, is the apportioning (or proportional division) of congressional seats (435 for the U.S. Congress since 1911) among the 50 states according to their relative population. Redistricting is the re-drawing of congressional districts within each state, according to the number of seats they were apportioned, again based on the new census data. Reapportionment causes redistricting. Reapportionment is objective data (though how the Census Bureau counts population does involve some political disputes, specifically dealing with how low-income citizens are fairly counted). Redistricting is the part where all of the political battles happen.

The process of setting up new congressional districts after reapportionment is called redistricting. It involves redrawing the boundaries of congressional districts to ensure each district has roughly the same population size based on the latest census data.
Congressional districts are redrawn every 10 years following the national census. This process is called redistricting, and the U.S. Constitution requires a census every 10 years for the purpose of redistricting Congressional districts.

districts must be equally populated. lines must be contiguous or connected. redistricting cannot dilute minority voting strength. district lines cannot be drawn solely based upon race. districts must be compact. communities of interest must be protected.
The census is helpful in many ways. The data collected can help determine population trends, which is helpful to school districts when determining taxes and redistricting. If population has changed drastically in a given area, it can affect the amount of representatives a state is given. The census can be used by business's to help determine which markets are best for them in terms of location. Cities can use a census to help determine tax rates. The census can also just be use purely for research.
