State by State Analysis of Whether Non-Citizens Will be Excluded from Redistricting Population Counts
Here's a state by state run-down of the likelihood that eleven states will exclude non-citizens from population counts for the purpose of redistricting. These are the top eleven states in terms of how much the change would harm the Democrats in state legislatures, with at least a one percent loss of seats in each.
In summary, excluding non-citizens from districting population counts is unlikely to occur in these states by legislative action, with the possible exception of AZ. However, it may come about through the initiative in AZ, CO, FL, or NV.
