Iowans are voting in new congressional, legislative districts. Here's how to find yours.

When early voting for Iowa's general election begins, many Iowans will be casting their ballot in a new set of congressional and state legislative district boundaries.

The new district lines were approved through last year's redistricting process, which takes place once a decade to account for changes in population.

That means your district might not look how you remember, and your incumbents may someone different than in the past.

Early voting begins Oct. 19 for the Nov. 8 general election, when statewide races like governor and U.S. senator are on the ballot, along with races for the U.S. House and Iowa Legislature, which have been altered by redistricting.
