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 — South Dakota residents owed around $20,700 less in household debt than the average American. In 2025, they owed around $10,900 less.

What is the debt-to-income ratio? How does it vary by county in South Dakota?
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, Harding County, SD had the highest debt-to-income ratio in the state of 8.12. This means that for every $1 of income earned, the average resident in Harding County, SD would owe $8.12. Alternatively, in Buffalo County, SD, residents experience around $0.14 for every $1 of income, the lowest of any parish in the state.
