KNOW YOUR GEOGRAPHY

County lines from the Missouri River to the Mississippi

The editor preserves Iowa’s county shapes, including the river boundaries at both sides of the state. County lines in the interior form many rectangular shapes, but the map uses the actual Census cartographic outlines.

Des Moines, Iowa City and Cedar Rapids are municipalities. The examples use county-level observations for Polk, Johnson, Linn and the other Census counties.

COMMON QUESTIONS

Iowa county map questions.

Can I use a Des Moines estimate as a Polk County value?

Use Polk County’s data for 19153. A city estimate covers a different area and should be labeled as such.

Which county should I use for Iowa City data?

Iowa City is in Johnson County, 19103. Choose county-level data when coloring the entire Johnson County polygon.

How do I locate Dallas County without matching Dallas, Texas?

Open the Iowa editor and join by 19049. The state prefix disambiguates the county even when the name appears elsewhere.

Can I compare the two sides of the Mississippi River?

Use the national county editor for a map that includes Iowa and neighboring states. Keep every row keyed to a five-digit Census GEOID.

What does the rent-burden map around Ames measure?

The Story County estimate covers the whole county. The denominator includes renter households with a computable gross-rent share of income.

How can I reproduce the Dallas and Polk migration contrast?

Use the pinned county estimates, divide net domestic migration by the average July 2024 and July 2025 population, and use a class boundary at zero.
