Redistricting done right

Centrists.Org -- Iowa's Redistricting Process: An Example of the Right Way to Draw Legislative...: "How The Iowa Process Works:  Under chapter 42 of the Iowa Code, enacted in 1980, the Iowa legislature has the final responsibility for enacting both congressional and state legislative district plans.  However, the nonpartisan Legislative Services Bureau starts the process.  The Bureau must develop up to three plans that can be accepted or rejected by the legislature.  

The four criteria for the Bureau's plans, in descending order of importance, are: 

1. population equality,
   
2. contiguity,
   
3. unity of counties and cities (maintaining county lines and “nesting” house districts within senate districts and senate districts within congressional districts), and 
   
4. compactness.
   

Chapter 42 specifically forbids the use of political affiliation, previous election results, the addresses of incumbents, or any demographic information other than population in creating the redistricting proposals."
