Overview

CITY (O'Fallon) Official statistic Source: U.S. Census Bureau, American Community Survey 2020–2024 5-year (via Census Reporter) · Data: ACS 2020–2024

How O'Fallon compares. Among the 100 largest places in Illinois, O'Fallon is #58 by population, #20 for long commutes (#1 = fewest), #25 for college degrees (#1 = most), #26 for remote work (#1 = most). Its county, Saint Clair County, is #27 of 102 counties for average pay ($57,001).

The place in numbers

O'Fallon has 32,262 residents (ACS 2020–2024), about 0.3% of the population of Illinois. It covers 16 square miles of land, which works out to roughly 2,041 people per square mile. The median age is 37.8, 3% younger than the state median (37.8 against 39.0).

Housing

The median gross rent is $1,332 a month (rent plus utilities), 5% above the state median ($1,332 against $1,274). Over a year that is 15.1% of the median household income. US housing guidance treats housing as affordable when it takes 30% of income or less, so the typical household is under that line. The median home value is $295,700, which is 2.8 times the median household income ($105,982); a ratio under 4 usually means ownership is within reach for many households. 70.2% of households own their home, 5% above the state average (70.2% against 67.1%).

The St. Louis, MO-IL metropolitan area has 1,341,320 jobs in the BLS wage survey, and the median pay across all occupations is $49,990 a year, about the same as the national median ($49,990 against $50,980). The biggest occupation groups are office and administrative support (149,950 jobs, median $46,840); food preparation and serving related (120,730 jobs, median $33,040); transportation and material moving (110,460 jobs, median $44,750). The area is most specialised in healthcare practitioners and technical (1.1 times) and healthcare support (1.1 times), where the share of workers is above the national share.

Getting around

Among workers, 70.5% drive alone, 0.5% use public transit, 2.2% walk, 20.4% work from home. 11.7% of workers commute 45 minutes or more, 41% below the state average (11.7% against 19.7%). Remote work is more common than in the state as a whole, which widens the set of employers a resident can work for without moving.

People and education

52.4% of adults aged 25 and over hold a bachelor's degree or higher, 38% above the state share (52.4% against 37.9%). 3.8% of residents were born outside the United States, 74% below the state share (3.8% against 14.8%). The poverty rate is 6.2%, 48% below the state rate (6.2% against 11.8%).

The warmest month is Jul, averaging 78°F (25.8°C), and the coolest is Jan at 30°F (-1.0°C). About 1,106 mm (44 inches) of precipitation falls in a year; May is the wettest month (130 mm) and Jan the driest (63 mm).
