Census, apportionment, and redistricting data

See also: United States census, 2020

Every ten years, the United States conducts the census, a complete count of the U.S. population. The data gleaned from the census process determines congressional apportionment (i.e., the number of seats each state has in the U.S. House of Representatives). Article I, Section 2, of the U.S. Constitution requires that congressional representatives be apportioned to the states on the basis of population. Consequently, a state may gain seats in the House if its population grows or lose seats if its population decreases, relative to populations in other states. There are 435 seats in the United States House of Representatives.[1]

Federal law requires congressional and legislative districts to have substantively equal populations. Consequently, states use census data during their redistricting processes to ensure compliance with this requirement.[1]

Timeline of key developments

  • September 16, 2021: The U.S. Census Bureau released data from the 2020 census in an easier-to-use format to state redistricting authorities and the public at data.census.gov.[2]
  • September 1, 2021: The U.S. Census Bureau announced that it would release easier-to-use formats of the data from the 2020 census at data.census.gov on September 16, 2021. The Bureau also said it would deliver DVDs and flash drives of the data to state legislatures and redistricting authorities on that date.[3] The Bureau had previously announced that it would release this summary data by Sept. 30.[4]
  • August 12, 2021: The U.S. Census Bureau released block-level data from the 2020 census, which includes county-level demographic information. This release allowed states to begin the process of drawing congressional and state legislative district maps. The Bureau announced it would also release a complete, tabulated version of the census dataset by Sept. 30, 2021. According to the Bureau's press release, "The 2020 Census showed that the adult (age 18 and older) population group grew 10.1% to 258.3 million people over the decade," and "The population of U.S. metro areas grew by 9% from 2010 to 2020, resulting in 86% of the population living in U.S. metro areas in 2020, compared to 85% in 2010."[4]
  • May 25, 2021: Ohio Attorney General Dave Yost (R) announced that the state had reached a settlement agreement with the Census Bureau in its lawsuit over the Census Bureau's timetable for delivering redistricting data. Under the terms of the settlement, the Census Bureau agreed to deliver redistricting data, in a legacy format, by August 16, 2021.[5]
  • April 26, 2021: The U.S. Census Bureau announced that it would release apportionment counts at 3:00 p.m. Eastern.[6]
  • March 15, 2021: The U.S. Census Bureau announced that redistricting data could be made available to states in a legacy format by mid-to-late August 2021.: "In declarations recently filed in the case of Ohio v. Raimondo, the U.S. Census Bureau made clear that we can provide a legacy format summary redistricting data file to all states by mid-to-late August 2021. Because we recognize that most states lack the capacity or resources to tabulate the data from these summary files on their own, we reaffirm our commitment to providing all states tabulated data in our user-friendly system by Sept. 30, 2021."[7]
  • February 12, 2021: The U.S. Census Bureau announced that it would deliver redistricting data to the states by September 30, 2021. The original deadline for delivering these data sets was April 1, 2021.[8]
  • January 27, 2021: Kathleen Styles, an official at the U.S. Census Bureau, announced that the bureau intended to deliver its final apportionment report by April 30, 2021. The original deadline for delivering the apportionment report was December 31, 2020. Styles also said the bureau hoped to release redistricting data after July 31, 2021.[9]
  • January 20, 2021: President Joe Biden (D) issued an executive order directing the Secretary of Commerce to include in the final apportionment report the "tabulation of total population by State that reflects the whole number of persons whose usual residence was in each State as of the designated census date in section 141(a) of title 13, United States Code, without regard to immigration status." This effectively overturned President Donald Trump's (R) earlier directive to the contrary.[10]
  • November 19, 2020: U.S. Census Bureau Director Steve Dillingham announced that, "during post-collection processing, certain processing anomalies [had] been discovered." Dillingham said that he had directed the bureau "to utilize all resources available to resolve this as expeditiously as possible."[11] Also on November 19, 2020, The New York Times reported that "a growing number of snags in the massive data-processing operation that generates population totals had delayed the completion of population calculations at least until January 26, [2021], and perhaps to mid-February."[12]

State-specific timelines for the 2020 redistricting cycle

Overview

The maps below provide information about projected redistricting deadlines in 2021, 2022, and 2023. These deadlines generally take one of three forms:[13]

  • 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.

Alabama

See also: Redistricting in Alabama after the 2020 census

The candidate filing deadline for the 2022 election cycle in Alabama was Jan. 28, 2022, an inferred redistricting deadline. On Oct. 14, 2021, Gov. Kay Ivey (R) called for a state legislative special session focused on redistricting to begin on Oct. 28.[14] Ivey signed new legislative and congressional maps into law on Nov. 4, 2021.

The board released its first draft maps on Sept. 9 and adopted a final state legislative map on Nov. 10, 2021, beginning a 30-day period, during which time any interested parties could file legal challenges against the map.[18] [19][20]

Arizona

See also: Redistricting in Arizona after the 2020 census

The candidate filing period for the 2022 election cycle in Arizona began on March 5, 2022, and ended on April 4, 2022. It was inferred that redistricting would be completed before then.[21]

Once the commission approves a final map, it begins a 26-day review process during which time counties can submit administrative and technical requests. At the end of that period, the commission holds a final vote.[22]

Arkansas

See also: Redistricting in Arkansas after the 2020 census

Arkansas' congressional and state legislative redistricting processes operate differently from each other with congressional redistricting carried out by the Arkansas General Assembly and state legislative redistricting conducted by the Arkansas Board of Apportionment.

Congressional redististricting
The Arkansas General Assembly was called back into an extended regular session on Sept. 29, 2021, in order to, among other items, consider proposed congressional redistricting boundaries.[23] On Oct. 7, 2021, the legislature approved two maps and sent them to Gov. Asa Hutchinson (R) for final approval. Hutchinson announced he would allow the maps to become law without his signature, meaning the maps would become effective 90 days later. On Nov. 4, 2021, Attorney General Leslie Rutledge (R) released a legal opinion saying the congressional district plan would become effective on Jan. 14, 2022.[24]

Legislative redistricting
The Board of Apportionment voted to accept new Senate and House maps on Oct. 29, 2021, beginning a public comment period. The board met on Nov. 29, 2021, to incorporate feedback and make any other alterations before final approval. The final maps became law on Dec. 30, 2021.[25]

California

See also: Redistricting in California after the 2020 census

On July 17 and Sept. 22, 2021, the California Supreme Court adjusted California's redistricting deadlines due to delays in the delivery of census data caused by the coronavirus pandemic. The state supreme court set Nov. 15 as the deadline for the release of initial draft district plans.[26] The commission displayed its final approved maps on Dec. 20, ahead of its court-ordered Dec. 23 deadline, with Dec. 27 as its deadline to certify those maps to the secretary of state.[27][28][29][30]

*Following the release of the preliminary draft district maps, the commission may not display any other maps for public comment for two weeks.


Colorado

See also: Redistricting in Colorado after the 2020 census

In Colorado, once the commission approves a final map, it must submit that map to the Colorado Supreme Court for final approval. On July 26, 2021, the Colorado Supreme Court adjusted submission deadlines due to delays in census data delivery related to the coronavirus pandemic. The court set Oct. 1 as the deadline to submit an approved congressional map and Oct. 15 as the deadline for the state legislative maps.[31] Once submitted, the state supreme had one month to either approve the map or send it back to the commission for further edits. The court approved the congressional map on Nov. 1 and the state legislative maps on Nov. 15.


Connecticut

See also: Redistricting in Connecticut after the 2020 census

According to the Connecticut Constitution, the Reapportionment Committee was required to select a map, which needed two-thirds approval from both chambers of the Connecticut General Assembly by Sept. 15, 2021. The committee failed to meet this deadline due to delays in the release of census data and was disbanded.[32]

Under state law, since the initial eight-member Reapportionment Committee failed to meet to Sept. 15 deadline, a nine-member Reapportionment Commission was formed with a final deadline of Nov. 30, 2021.[33] The commission failed to complete congressional redistricting by the Nov. 30 deadline. Under state law, the Connecticut Supreme Court assumed control over the redistricting process on Dec. 1, 2021.[34][35] The Connecticut Supreme Court granted the commission an extended deadline of Dec. 21, but the commission failed to complete a congressional map by that time.[36] Read more here.

The Connecticut Supreme Court must complete congressional redistricting by Feb. 15, 2022.[37]

Iowa

On September 14, 2021, the Iowa Supreme Court ruled that they were extending the deadline for state legislative redistricting to December 1, 2021. The last two paragraphs are quoted below:[48]

The LSA (Legislative Services Agency) has indicated that because of the delayed delivery of the 2020 decennial census data to the State of Iowa, the reapportionment process will not be concluded before September 1, 2021, and the apportionment will not become law before September 15, 2021. Because of this, the constitution now vests the supreme court with the responsibility and authority to “cause the state to be apportioned.” Iowa Const. art. III, § 35.


Pursuant to its constitutional authority to “cause the state to be apportioned,” the supreme court permits the parties identified in Iowa Code chapter 42 (2021) to prepare an apportionment in accord with Iowa Code chapter 42 (2021) by December 1, 2021.[49]


On April 8, 2021, the Iowa Supreme Court released the following statement on its role in the post-2020 census redistricting cycle:[50]

If the general assembly is not able to meet the constitutional deadline, the supreme court tentatively plans to meet its constitutional responsibility by implementing a process which permits, to the extent possible, the redistricting framework presently set forth in Iowa Code chapter 42 to proceed after September 15. Under such a process, the supreme court would “cause the state to be apportioned into senatorial and representative districts to comply with the requirements of the constitution prior to December 31."[49]

The court added, "Legally and constitutionally, the supreme court cannot commit to a future course of action beforehand. Thus, the statement herein should not be considered legally binding."[50]

Kentucky

See also: Redistricting in Kentucky after the 2020 census

According to Joe Sonka of the Louisville Courier Journal, the "Kentucky General Assembly kicked off the first day of its 2022 legislative session Tuesday [January 4, 2022], with Republicans in both chambers filing redistricting bills that are expected to speed to final passage by Saturday [January 8, 2022]."[53]

Sonka continued, "The redistricting bills are expected to speed to final passage on Saturday [January 8, 2022] and head to the governor's desk for his signature, though the deadline for candidates to file for office is Friday [January 7, 2022]. [Senate President Robert] Stivers said he expects both the House and Senate to pass identical bills this week to push back the filing deadline a few weeks, saying he expects both chambers to waive the required three readings of bills to pass both in one day. A Senate committee will take up the two redistricting bills Wednesday [January 5, 2022] morning, while a House committee at noon will take up the House redistricting bill, one that pushes the filing deadline back to Jan. 25 and another that redistricts the Kentucky Supreme Court.[53]

Louisiana

See also: Redistricting in Louisiana after the 2020 census

The House Committee on House and Governmental Affairs and the Senate Committee on Senate and Governmental Affairs announced they would hold a series of joint meetings throughout the state from October 2021 through January 2022 where citizens could make suggestions and recommendations regarding redistricting.[54]

The Louisiana legislature opened a special session addressing redistricting on February 1, 2022, that was scheduled to last three weeks.[55]

Maine

See also: Redistricting in Maine after the 2020 census

On July 19, 2021, the Maine Supreme Judicial Court established a revised timeline for redistricting in the state. In a unanimous decision, the Court established the following deadlines:

  • The Maine Apportionment Commission must submit legislative and congressional plans “45 days after the State of Maine’s receipt from the Census Bureau” of legacy-format data.
  • The legislature must enact either the Apportionment Commission’s plan or its own plan 10 days after the earlier of the Commission’s submission of redistricting plans or the expiration of the 45 day deadline for the Commission to submit plans.

If the legislature fails to enact an apportionment plan by the deadline, the Court has 35 days to enact its own plan for legislative and congressional redistricting.

The Court’s ruling was necessary because the Maine Constitution requires the Apportionment Commission to submit redistricting plans by June 1, which was not possible since the Census Bureau did not deliver census data to the states until August 12, 2021.[56]

In late May 2021, Senate President Troy Jackson (D), House Speaker Ryan Fecteau (D), Senate Minority Leader Jeffrey Timberlake (R), and House Minority Leader Kathleen Dillingham (R) petitioned the Maine Supreme Judicial Court to extend the deadline for the advisory commission to submit its recommendations to the state legislature until 45 days after receiving data from the U.S. Census Bureau.[57]

New Jersey

See also: Redistricting in New Jersey after the 2020 census

On August 18, Secretary of State Tahesha Way (D) said New Jersey would certify redistricting data upon its receipt of tabulated data from the U.S. Census Bureau, delaying the beginning of the redistricting process in New Jersey until then. The U.S. Census Bureau released data in a legacy format on August 12, and released tabulated data on September 16.[78][79] Way said census data adjusted to count incarcerated individuals at their last residence rather than at their place of incarceration would be released on September 23.[80] The redistricting process officially began a month later on October 23. The deadline for approval of congressional redistricting maps was January 18, 2022. The deadline for approval of legislative redistricting maps was March 1, 2022. In January 2022, Philip J. Carchman said the commission would make legislative maps available to the public by February 8, 2022.[81]


On November 3, 2020, New Jersey voters approved Public Question 3, a constitutional amendment postponing state legislative redistricting until after the November 2, 2021, election if the census bureau failed to deliver redistricting data by February 15, 2021. The application of this postponement was triggered as a result of the census bureau's announcement that it did not expect to deliver redistricting data to the states until after July 31, 2021. Consequently, the existing legislative district maps were set to remain in force until 2023.[82]

New Mexico

Under SB304, the deadline for the advisory commission to submit its proposals to the state legislature was set for October 30, 2021, "or as soon thereafter as practicable."

On December 2, Gov. Michelle Lujan Grisham called for a special session of the state legislature to address redistricting to begin on December 6.[85]

New York

See also: Redistricting in New York after the 2020 census

The New York Independent Redistricting Commission released its first redistricting proposals to the public on September 15, 2021.[86] As of the 2020 redistricting cycle, state law provides a deadline of "on or before January 1, 2022, or as soon as practicable thereafter, but no later than January 15, 2022," for the first map submission. If the legislature is unable to approve the plan or the governor vetoes the plan, the commission has 15 days to submit a second plan for consideration. This second plan may be submitted no later than Feb. 28, 2022.[87]

North Carolina

On February 23, 2021, Karen Brinson Bell, executive director of the state board of elections, recommended that state lawmakers postpone North Carolina's 2022 primary election, scheduled for March 8, 2022, by two months.

There are no plans to move the primaries.”[88]

North Dakota

Ohio

See also: Redistricting in Ohio after the 2020 census

On August 2, 2021, Governor Mike DeWine (R) announced the Ohio Redistricting Commission would hold its first meeting on August 6.[90] The commission did not meet the first legislative map completion deadline of September 1. The second and final deadline was September 15.

The first congressional map deadline was September 30. Senate President Matt Huffman (R) said he did not expect the legislature to meet the congressional map deadline, saying: "I think it’s going to be – under the circumstances – difficult to meet for a couple of reasons."[91] Since a congressional map wasn't completed by that date, the Ohio Redistricting Commission had to draw a map by October 31. Since the commission did not adopt a map, the General Assembly had to draw a map by November 30.[92]

According to a February 12, 2021, report from the Associated Press, Pennsylvania state Senate President Pro Tempore Jake Corman (R) said the state might have to postpone its 2022 primary, scheduled for May 17, 2022.

Redistricting after the 2010 census

See also: State redistricting timelines following the 2010 census

Although postponements to the 2020 redistricting process will result from the aforementioned census delays, the 2010 timeline suggests the concentration of activity that might take place once the 2020 cycle begins in earnest.

In the 2010 redistricting cycle, redistricting authorities enacted 43 new congressional district maps and 50 new state legislative district maps. The majority of these – 63 maps (31 congressional and 32 state legislative), 67.74 percent of the total– were enacted in 2011. In 2012, 28 maps (12 congressional and 16 state legislative) were enacted, 30.11 percent of the total. The remaining maps were enacted in the first six months of 2013.

The table and bar charts below list congressional and state legislative district map enactment dates for all 50 states in the 2010 cycle. These graphics do not take into account maps that were subsequently redrawn.
