Poor single mothers in Egypt often borrow money from the bank to support their families. They also buy on credit things like a daughter's trousseau. Then they fail to pay off their debts and end up in jail. The Arabic word for women who go to jail as a result of failing to pay their debts is gharimat. How can we describe them in English with as few words as possible? I'm thinking defaulters.
Edit
I intend to use the word in a news headline:
Mr. X's philanthropy releases 500 gharimats from prison.
