The U.S. Census Bureau released a ton of new Iowa demographic information yesterday.
Data for Iowa show that the five most populous incorporated places and their 2010 Census counts are Des Moines, 203,433; Cedar Rapids, 126,326; Davenport, 99,685; Sioux City, 82,684; and Waterloo, 68,406. Des Moines grew by 2.4 percent since the 2000 Census. Cedar Rapids grew by 4.6 percent, Davenport grew by 1.3 percent, Sioux City decreased by 2.7 percent and Waterloo decreased by 0.5 percent.
The largest county is Polk with a population of 430,640. Its population grew by 15.0 percent since 2000. The other counties in the top five include Linn, with a population of 211,226 (increase of 10.2 percent); Scott, 165,224 (increase of 4.1 percent); Black Hawk, 131,090 (increase of 2.4 percent); and Johnson, 130,882 (increase of 17.9 percent).

Rick Smith’s piece on growth in the Cedar Rapids-Iowa City corridor is worth a read. I’m not surprised Linn County grew substantially during the decade, especially in the suburbs, but the population growth in Cedar Rapids itself is impressive. I didn’t expect to see that after the 2008 floods destroyed whole neighborhoods in the city.
After the jump I’ve posted official 2010 population numbers for all 99 Iowa counties, along with a map putting the counties in different population categories and a map grouping counties by population gain or loss (percentage). Ten Iowa counties have populations larger than 65,000 people. Another 14 counties have populations between 25,000 and 64,999; 29 counties have populations between 15,000 and 24,999; and 46 counties have populations between 4,029 (Adams) and 14,999. Dallas led the 33 Iowa counties that gained population between 2000 and 2010.
Although I wasn’t able to reproduce this chart showing the racial and ethnic breakdown of the Iowa population by Congressional district, I did include those numbers at the end of this post. I was surprised to see that even though Polk County has the largest Latino/Hispanic population in Iowa, there are more Latino/Hispanic residents in IA-05 than in IA-03, with IA-02 and IA-04 not far behind. Meanwhile, IA-01 has the smallest Latino/Hispanic population but the largest African-American population. The largest Asian population is in IA-03 with IA-02 not far behind.

UPDATE: The Des Moines Register has lots of census coverage here. Statewide, Iowa’s population grew by 4.1 percent from 2000 to 2010. The Latino population was up by 83.8 percent, the Asian population was up by 44.9 percent, and the African-American population was up by 44.1 percent.Continue Reading...
