Discover the Largest Cities in Iowa (By Population, Total Area, and Economic Impact)

Iowa is one of the 12 states that comprise the Midwest. Known for its “black gold” fertile topsoil, about 85 percent of the land in Iowa is used for agriculture. As the country’s top pork and corn producer, it’s no wonder that Iowa is one of the top three farmland states in the U.S. That might explain why Iowa is only the 32^nd most populated state in the Union, even though it ranks 23^rd for land size. However, if you are planning to move to the state, here are some of the largest cities in Iowa.

Largest Cities in Iowa by Population

1. Des Moines

As the state’s capital city, it’s no surprise that this is the largest city in Iowa. Des Moines has a population of 211,034. However, this number reflects a 1.4 percent loss compared to its population in 2020, which was 214,125.

According to the United States Census Bureau, the median household income in Des Moines is $58,444. That’s below the median household income in the United States, which was $74,580 in 2022. About 15.3 percent of the city is living below the poverty line.

But the bright spot is that the cost of living in Des Moines is 14 percent lower than in the nation and seven percent lower than the state’s average. On top of that, in this crazy housing market, housing in Des Moines is 32 percent cheaper than the national average.

2. Cedar Rapids

As the second largest city in Iowa, Cedar Rapids has a population of 136,429. This number is also down 0.9 percent from the census number in 2020, which was a population of 137,723. The median household income is $63,170, and unfortunately, it’s estimated that 11.2 percent of people are living in poverty. While these numbers are a bit better than in Des Moines, the trade-off is that the cost of living is four percent higher in Cedar Rapids than in Des Moines.

3. Davenport

With a population of 100,486, Davenport is the third most populated city in Iowa. While the city saw a 1.2 percent drop in population compared to 2020, the cost of living in Davenport is three percent lower than the national average. The median household income is $56,315, which is the lowest of the top three most populated cities in Iowa. And 15.8 percent of the population are in poverty.

Coming in fourth by population is Sioux City, with a population of 85,497. This city has the second smallest decline rate of the five, with just a 0.3 percent drop in population compared to 2020. The median household income is higher than in Des Moines and Davenport at $59,435. Sioux City also has a lower percentage of people living in poverty than in Des Moines and Davenport, with a rate of 14.7 percent. Additionally, Sioux City is more affordable, and the cost of living is three to four percent lower in Sioux City than in Des Moines, Cedar Rapids, or Davenport.

5. Iowa City

As the fifth largest city in Iowa, with a population of 75,233, Iowa City actually grew in size since 2020. With a 0.5 percent growth, Iowa City grew from a population of 74,823 in 2020 to the current number. The median household income is $51,925, which is the lowest of the five most populated cities in Iowa. Also, an estimated 26.8 percent of the population lives in poverty. One contributing factor may be that the cost of living in Iowa City is four to seven percent higher than in Des Moines, Cedar Rapids, Davenport, or Sioux City.
