About Clinton County, Illinois

Above National Median in Stability

Clinton County achieves a composite score of 52.0, placing it slightly above the national median of 50.0. This score indicates a stable, middle-of-the-road American living experience. It balances high earning potential with some environmental and cost challenges.

Steady Competition with State Norms

The county's score of 52.0 is just below the Illinois state average of 52.8. While it is a high-earning area, other Illinois counties provide slightly better overall value when taxes and risks are considered. It remains a prosperous, if somewhat expensive, Illinois option.

High Incomes and Excellent Health

Income is the county's standout feature, with a score of 86.1 and a median household income of $82,314. Health outcomes are also impressive, scoring 82.9, while safety remains strong at 78.5. These scores point to a community of affluent, healthy residents.

High Costs and Tax Burden

The tax score of 4.6 and cost score of 32.1 reflect a higher-than-average cost of living for the region. Water quality also trails behind with a score of 31.0. High home values of $180,500 and high property taxes make this a more expensive place to settle down.

The Verdict: Suited for High-Earner Families

Clinton County is the best fit for high-earning professionals who want a healthy and safe environment and can afford the premium. Its strong health and income metrics are its biggest selling points. It is less suited for those seeking a bargain or maximum environmental stability.

A warm, wet climate above national averages

Nearly three degrees warmer than the state average

As one of the warmest counties in Illinois, Clinton’s 55.7°F average is nearly three degrees higher than the state average. This warmth is a defining characteristic of its location in the southwestern part of the state.

High July heat compared to eastern neighbors

Soil Quality in Clinton County

via SoilByCounty

Typical Illinois Soil Characteristics

Clinton County features an average soil pH of 6.37, which is nearly identical to the state average of 6.39. This level is slightly more acidic than the national median of 6.5, but remains well within the preferred range for most Midwestern agriculture. This chemical consistency provides a predictable foundation for local farmers and gardeners alike.

Fine-Textured Silt Dominates the Landscape

The soil composition is 65.1% silt and 21.4% clay, with a low sand fraction of 13.4%. This heavy silt profile creates a smooth, dense soil that is very effective at trapping nutrients but can be slow to drain. It requires careful management to prevent compaction, especially when using heavy machinery on wet ground.

High Water Retention for Crop Security

Clinton County excels in water storage with an available water capacity of 0.214 in/in, well above the state average of 0.204 in/in. However, organic matter is lower than the state average at 2.21%. This suggests that while the soil is great at surviving dry spells, it may need supplemental fertilization to reach peak productivity.

Sponge-Like Soil Performance

While formal drainage classes are not provided, the high water capacity of 0.214 in/in suggests the soil acts as an efficient reservoir. The high silt and clay levels mean water moves slowly through the profile, which can lead to ponding in flat areas during heavy rains. This makes drainage management a priority for local land development and farming.

Thriving in the Warmth of Zone 6b

The Zone 6b climate in Clinton County allows for a diverse range of crops, including berries and hardy vegetables. Your soil is excellent at holding water, which is a major advantage during the hot Illinois July and August. Adding organic compost will help bridge the gap in soil fertility and ensure a bountiful home harvest.

Lawn Care in Clinton County

via LawnByCounty

Stable Growing Conditions in Clinton

Clinton County holds a lawn difficulty score of 65.9, reflecting a moderately challenging but rewarding environment for Zone 6b turf. This score is slightly below the Illinois average but remains very manageable for dedicated homeowners. The local climate supports a robust growing season for those who plan ahead.

Wet Springs and Long Seasons

The county enjoys 42.9 inches of annual rain, which is plenty to support its impressive 4,186 growing degree days. While there are 32 days of extreme heat, the consistent precipitation helps maintain turf vitality. This long season means you will be mowing well into late October.

Dense Soil with Good Nutrient Potential

A soil pH of 6.37 is nearly ideal for most grass types, ensuring fertilizer works efficiently. The soil is heavy on clay at 21.4% and light on sand at 13.4%, which can cause water to pool after heavy storms. Core aeration is highly recommended to help break up this density and improve root depth.

Strong Resilience Against Severe Drought

Remarkably, 0% of Clinton County is currently in severe drought, despite 27 weeks of dry weather over the past year. This makes it a regional leader in drought resilience compared to its neighbors. Standard watering practices are usually sufficient here without the need for emergency conservation measures.

Extended Growth Period for Zone 6b

With a long growing season, you can start spring work as early as April 6 and continue through the first fall frost on October 29. Use a mix of Tall Fescue and Kentucky Bluegrass to handle both the heat and the winter chill. The late October frost date gives new seedlings plenty of time to establish.
