KNOW YOUR GEOGRAPHY

Lake Michigan, the Illinois River and the southern tip.

Illinois stretches from Lake Michigan to the meeting of the Ohio and Mississippi rivers. Cook is one selectable county, while DuPage, Lake, Will and Kendall are separate features with their own Census GEOIDs.

County data describes whole county populations. A regional label such as Chicagoland needs its county membership defined before you aggregate values or group features.

County growth and decline fit on one statewide scale.

Thirty-eight counties gained population and 64 declined. Kendall gained 1.64%, and Bond led percentage growth at 2.16%. Rates compare relative change, so a small county can lead without accounting for the largest number of added residents.

COMMON QUESTIONS

Illinois county map questions.

Can I color Chicago independently of Cook County?

The map selects Cook County as a whole. To map Chicago’s city limits or neighborhoods, use geography and data defined at those levels.

Which codes distinguish Cook, DuPage and Kendall?

Cook is 17031, DuPage is 17043, and Kendall is 17093. Keep the five characters together in your join column.

How do I highlight the Chicago region?

Choose the counties included in your definition of the region, then group and style their individual features. The map does not define a single Chicagoland boundary.

What does the Illinois income map measure?

It shows the estimated median household income for each entire county, in 2024 dollars. Areas beyond its largest city contribute to that estimate.

Why is Kendall a different color from Cook on the migration map?

Kendall had a positive net domestic migration rate and Cook had a negative one for July 2024 to July 2025. The classes split losses from gains at zero.

How should I compare Illinois and Missouri counties in one export?

Use the national county editor and five-digit GEOIDs so counties on both sides of the Mississippi can appear in the same map.
