Compared to the previous year, the average adult owed $745 less debt after adjusting for inflation, reflecting slight shifts in household borrowing patterns.

Debt levels also fluctuate over time, especially during times of economic instability. According to the Federal Reserve Bank of New York, household debt increased in the early 2000s, largely driven by housing debts like mortgages. Following the downturn in home prices and the onset of the Great Recession in late 2007, people began paying off their existing loans while taking out fewer new loans, leading to a decline in overall debt levels.
In 2007, during The Great Recession — a debt peak for the US — Illinois residents owed around $1,100 less in household debt than the average American. In 2025, they owed around $9,200 less.

While household debt takes many forms — student loans, auto loans, credit card balances — mortgage debt accounted for around 67.5% of all household debt in Illinois in 2025.

What is the debt-to-income ratio? How does it vary by county in Illinois?
Another important aspect of household debt is the debt-to-income ratio. This ratio compares how much debt a person carries with how much income they earn in a year. If the ratio is greater than 1, it means that, on average, people owe more than they earn annually. This can indicate a heavier financial burden and make it harder to keep up with payments.
Debt-to-income ratios vary from parish to parish within a state because of differences in income levels, housing costs, and borrowing habits. In 2024, Kendall County, IL had the highest debt-to-income ratio in the state of 5.31. This means that for every $1 of income earned, the average resident in Kendall County, IL would owe $5.31. Alternatively, in Brown County, IL, residents experience around $0.26 for every $1 of income, the lowest of any parish in the state.
