This analysis of government data estimates that 9% of adults – or roughly 23 million people – owe more than $250 due to health costs. About half of those reporting significant medical debt owe more than $2,000. A small share (representing about 1 percent of all adults) owes more than $10,000, and the group accounts for the vast majority of all medical debt owed by people in the United States.
