TOPEKA, Kan. (AP) — Kansas voters are deciding whether to end the state’s unusual policy of using its own numbers in addition to federal census data to redraw boundaries of state legislative districts.

The ballot in Tuesday’s election includes a proposed amendment to the Kansas Constitution to eliminate a requirement for the state to adjust federal census figures when the Legislature redistricts itself.

The adjustment counts college students and military personnel not where they’re living but in a “permanent” home elsewhere. That’s outside Kansas for thousands of people and the practice has cost university towns some political clout.

Secretary of State Scott Schwab argues that the policy is outdated and says the next adjustment for 2022 would cost $835,000.

Kansas is among only a few states that adjust federal census figures for redistricting.
