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.
