Elections by District.
Local jurisdictions conduct elections in a variety of ways for local boards, commissions, and other multi-member bodies.  Some common voting methods include at-large, district-based, and hybrid election systems.  In an at-large election, candidates are elected from voters of the entire jurisdiction.  In a district-based election, the jurisdiction is divided into separate districts and each candidate is elected by the voters of a district in which the candidate resides.  A hybrid system has elements of both at-large and district-based election systems.  For example, a primary may be district-based, with candidates facing off in an at-large general election.  Certain counties, cities, and special purpose districts use such a hybrid system for electing the governing body of the jurisdiction.  Eight first-class cities, two second-class cities, and 17 optional municipal code cities use some form of district-based elections to elect council members.  The 32 noncharter counties in the state, which are counties that have not adopted a "home rule" charter to provide for their own form of government, are required to use the hybrid system for electing its commissioners.  Counties adopting home rule charters may adopt different systems for electing their commissioners.
 
With exceptions, the Voting Rights Act authorizes counties, cities, towns, school districts, fire protection districts, port districts, and public utility districts to change its electoral system to implement a district-based election system if at-large voting would impair the ability of members of a protected class or classes to have an equal opportunity to elect candidates of their choice.
 
Redistricting.
Under the direction of the state Constitution, in January of each year ending in one, the state Redistricting Commission (Commission) is established to provide for the redistricting of state legislative and congressional districts.  The Commission must complete redistricting as soon as possible following the federal decennial census, but no later than November 15 of each year ending in one.
 
Each county, city, and special purpose district which elects all or part of its governing body using the district-based method must prepare a plan for redistricting after each decennial census.  The Commission must forward census data to such local jurisdiction within 45 days of receipt from the Census Bureau.  The local jurisdiction must then prepare a redistricting plan within eight months of receipt of the data from the Commission.

2020 Census.
The Census Bureau conducts the census at 10-year intervals.  At the conclusion of each census, the results are used to determine apportionment and redistricting for congressional and legislative districts in each state.  Apportionment is the process of dividing the 435 seats in the United States House of Representatives among the 50 states.  Federal law requires that the apportionment population counts be delivered to the President within nine months of the decennial census date.  Typically, the decennial census date has been April 1 of the census year, which means the apportionment population counts would be due by December 31.  In addition, the statutory deadline for providing redistricting data to the states is one year after the decennial census date.
 
The Census Bureau announced delays in delivering data from the 2020 Census caused by circumstances related to COVID-19.  On January 27, 2021, the Census Bureau announced an estimated delivery time for apportionment data of April 30, 2021.  On February 12, 2021, the Census Bureau announced that it expects to release redistricting data by September 30, 2021.

The deadline for counties, cities, and special purpose districts which elect all or part of its governing body using the district-based method to submit its redistricting plan is modified and two timelines are established.  Until January 1, 2023, for local jurisdictions scheduled to elect members to its governing body in 2022, redistricting plans are due by December 1, 2021.  Local jurisdictions not electing members in 2022 must submit a redistricting plan by November 15, 2022.  Beginning on January 1, 2023, all counties, cities, and special purpose districts that elect all or part of its governing body using the district-based method must prepare a redistricting plan by November 15 of each year ending in one, rather than the earlier of eight months after the receipt of the federal decennial census data or November 15 of each year ending in one.
