Ranks compare this state against all reporting states using ZIP-level Census ACS 5-Year aggregates.
Iowa (IA) contains 934 ZIP codes spread across 100 counties and 890 distinct cities. Together those ZIP areas cover a total population of 3,046,945 based on Census ACS 5-Year Estimates. ZIP-level granularity matters here: Iowa stretches across very different economic zones, and a single state-wide average hides the 10x spread you will see between its highest-income and lowest-income ZIP codes in the table below.
The economic baseline across Iowa ZIPs shows an average median household income of $76,594 and an average home value of $175,588, with a state-wide average median age of 43.6. These averages are computed over every ZIP in IA with reported data, not weighted by population, so small rural ZIPs count the same as metropolitan ones. Use them as a reference line, then drill into the ZIP tables to see where affluent suburbs, rural counties, and urban cores deviate from the state mean.
The largest urban concentrations in Iowa by population are Des Moines, Cedar Rapids, Davenport, Sioux City, Iowa City, and each city aggregates multiple ZIP codes worth of Census data on its own city page. Every record in this view comes from publicly available federal datasets, primarily the U.S. Census Bureau American Community Survey and USPS ZIP Code Tabulation Area files, with no proprietary scoring, estimation, or editorial adjustment. Click any county to drill down to its ZIP-level detail, or jump directly to a ZIP code to see household income, housing cost, demographic breakdown, nearby ZIPs, and FHFA home-price history for that specific five-digit area.
