Iowa set to keep four Congressional districts until at least 2030

good question

Most of Iowa’s counties continue to lose population, so it is likely that what constitutes the fourth Congressional district will continue to be very large geographically.

Given continuing population growth in Polk and Dallas counties, and to a lesser extent in Warren County, there seems to be a good chance that the third district will become more compact geographically after the next round of redistricting. It’s possible that the fourth district will look more like the fifth district did during the 2000s, covering all of Iowa’s westernmost counties and including Sioux City and Council Bluffs as the largest population centers.

Other than that, hard to predict what may happen. The 2000s map had Scott County in the first district and Linn County in the second district.
