View the chart: Demography of Idaho
This series of graphs makes use of U.S. Census data to compare Idaho’s counties to the nation as a whole on demographic measures such as age distribution, ethnic diversity, and place of birth.
Northern Idaho has fewer residents under age 18 and more residents over 65 than the southern part of the state. The northern counties have a larger percentage of residents who are white and non-Hispanic than the southern, and especially southwestern counties. The U.S. Census collects data on the portion of Americans who reside in the state in which they were born, the portion who were born in a different state, and the portion who were born in another country or in a U.S. territory. In most Idaho counties, the portion of foreign-born residents was smaller than that of the U.S. as a whole. Except for a few counties in eastern Idaho, the portion of residents who were born in the state they currently reside in was smaller than for the U.S. as a whole.
