Aurora, IL population, income and ZIP codes

Aurora city is a mid-size city in Illinois, with 179,867 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #2 of 1,462 ranked by population — larger than 99% of them. The median age here is 35.2 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Aurora city earn a median of $90,109 a year, 14.7% above the national figure of $78,538 and 21% above the $74,244 median for the 698 Illinois cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 9.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Aurora city is valued at $260,400, 14.2% below the national figure and 45% above the $179,100 peer median, while median gross rent runs $1,535 a month, 9.2% above the national figure, or roughly $18,420 across a full year. A household on the local median income would put about 20.4% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 66.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
