State redistricting deadlines in 2021, 2022 and 2023

The U.S. Census Bureau announced in February that it would deliver the detailed datasets needed for redistricting to the states by Sep. 30, 2021, after the original April 1, 2021, deadline. Some states’ own redistricting deadlines predate the Census Bureau’s projected data delivery date, prompting states to consider postponements or alternative data sources.

State redistricting deadlines generally take one of three forms:

♦ Constitutional deadlines are set out explicitly in state constitutions. Altering these deadlines typically requires either a constitutional amendment or a court order.

♦ Statutory deadlines are set by state legislatures. They are subject to change at the legislature’s discretion.

♦ Redistricting deadlines can also be inferred from candidate filing deadlines. For example, if a state sets its filing deadline for congressional candidates for Feb. 1, 2022, it can be inferred that the congressional maps must be fixed by that point.

Congressional redistricting

deadlines

Maine’s constitutional June 1, 2021, deadline for congressional redistricting is the earliest such deadline of any state. Five states – Colorado, Connecticut, Hawaii, Illinois, and Ohio – have congressional redistricting deadlines in the third quarter of 2021. Another six states – Michigan, North Carolina, Texas, Utah, Virginia, and Washington – have deadlines in the final quarter of 2021. The remaining states have deadlines in 2022.

State legislative redistricting deadlines

Indiana’s deadline for state legislative redistricting, which is set by statute, is April 29, 2021, earlier than that of any other state. Five other states – Delaware, Illinois, Maine, Nevada, and Oklahoma

– have state legislative redistricting deadlines in the second quarter of 2021. Another eight states – Colorado, Connecticut, Hawaii, Iowa, New Hampshire, Ohio, Oregon, and Vermont – have deadlines in the third quarter of 2021. Nine states – Alaska, Massachusetts, Michigan, North Carolina, South Dakota, Texas, Utah, Virginia, and Washington – have deadlines in the final quarter of the year. The remaining states have deadlines in either 2022 or, in the case of Montana, 2023.
