The U.S. Census Bureau has released “key demographics” of all U.S. congressional districts. Here’s the link.
In addition to the raw number of residents in each district, there is a racial breakdown as well as an average income for each district. It also lists the number of homeowners and the number of renters, the “educational attainment” of the residents in the district and how many military veterans live in the area.
For example, residents in the new third district that includes the Des Moines metro as well as Council Bluffs (represented by Congressman Tom Latham) have an average income of $54,641. The lowest average income is in northwest and north central Iowa’s fourth district (represented by Congressman Steve King) and that figure is $45,454. As for the two eastern Iowa congressional districts, the first district that includes the cities of Cedar Rapids, Dubuque and Waterloo (represented by Congressman Bruce Braley) has an average income of $50, 125. The second district includes the cities of Davenport and Iowa City (represented by Congressman Dave Loebsack) and the average income of residents in that district is $47,391.
