Cahokia Heights, Illinois
Area Profile
17,106 residents. Public schools, jobs, income, housing cost, climate and natural-hazard risk for Cahokia Heights.
Missing required signals: opportunity, resilience. AreaProfile withholds a score rather than inferring the missing dimensions.
Residential permitting has slowed: 0 units authorized over the past twelve months, 100% below the prior year.
Rent takes 35% of median household income here, at or above the 30% threshold conventionally called cost-burdened, and the median home is 1.7 times that income.
A major airport is 17 miles away, giving the area unusually direct access to the national air network.

Housing & affordability
How it’s calculated →Median rent of $981 takes 35% of median household income, above the 30% threshold at which a household is considered cost-burdened.
A median home costs 1.7 times median household income here, close to the historic benchmark for an affordable market.
| Metric | Value | Compared nationally | Source period |
|---|---|---|---|
| Home price to income | 1.66 | Bottom 14%of 28,473 | 2024 ACS 5-Year |
| Homeownership rate | 52.2% | Bottom 11%of 31,843 | 2024 ACS 5-Year |
| Housing units ±585 | 8,469 | Top 7%of 32,330 | 2024 ACS 5-Year |
| Median gross rent ±$88 | $981 | Top 49%of 23,432 | 2024 ACS 5-Year |
| Median home value ±$4,657 | $56,000 | Bottom 4%of 29,342 | 2024 ACS 5-Year |
| Rent as a share of income | 34.8% | Top 3%of 23,201 | 2024 ACS 5-Year |
| Vacancy rate | 28.5% | Top 14%of 32,001 | 2024 ACS 5-Year |
Both affordability measures come from the same ACS release as the income they are compared with, so the comparison is like for like. They describe housing cost against local earnings and are not a cost-of-living index — transport, groceries, healthcare, insurance and taxes are not included, and a place can look affordable here and still be expensive to live in for reasons this does not capture.
Growth & development
How it’s calculated →An AreaProfile calculation combining permit volume per resident, its direction over one and three years, population change and employment growth. Permit volume alone is not the measure.
Population has fallen 4% since 2020, reaching 17,052 in 2024.
At 0.0 permitted units per 1,000 residents, building activity is below the median for measured US cities.
Weather & climate
7 of the twelve months have a normal average temperature between 55°F and 80°F. July averages a high of 89°F and January a low of 24°F.
Normal annual precipitation is 40.8 inches.
| Metric | Value | Source period |
|---|---|---|
| Annual precipitation | 40.8" | 1991-2020 Normals |
| Average January low | 24°F | 1991-2020 Normals |
| Average July high | 89°F | 1991-2020 Normals |
| Comfortable months | 7 | 1991-2020 Normals |
| Seasonal temperature swing | 47°F | 1991-2020 Normals |
Climate figures are thirty-year normals, not current conditions. They describe what a typical year looks like rather than what the weather is doing today.
What this profile does not cover
Three things people look for are missing from every AreaProfile page, and each is missing for a reason rather than by oversight. The Area Score is calculated without them and the weighting is documented on the methodology page.
- Reported crime
- The FBI’s Crime Data Explorer is the only source for reported offences with national coverage and a published method, and it requires an API key AreaProfile does not hold. Arrest counts, news volume and commercial “safety scores” are not substituted in the meantime. What is published above under Safety is a different measurement — deaths rather than offences, from death certificates rather than police returns — and it covers no property crime at all.
- Taxes
- No tax dataset has met the source admission test for coverage, transparent methodology and update cadence. Nothing here is individualized tax advice.
- Full cost of living
- No public source publishes one with national coverage and a documented method. Housing affordability above is computed from published rent, price and income, and excludes transport, groceries, healthcare, insurance and taxes — commuting cost in particular tends to offset suburban housing savings.
Access
4 major airports lie within 100 miles, the nearest 17 miles away.
| Airport | Code | Distance | Longest runway |
|---|---|---|---|
| St Louis Lambert Intl | STL | 17 mi | 11,020 ft |
| St Louis Rgnl | ALN | 23 mi | 8,099 ft |
| Veterans Airport of Southern Illinois | MWA | 84 mi | 8,012 ft |
Airport identity, position and runway data come from the FAA. “Major airport” is an AreaProfile classification — a public-use civil airport with a paved runway of at least 8,000 feet — not an FAA hub designation. Distances are straight-line, not driving distance.
