Katherine Porter’s book, Broke: How Debt Bankrupts the Middle Class, is a group of essays based on the 2007 Consumer Bankruptcy Project. The 2007 CBP collected basic information on substantially all Chapter 7 (liquidation) and Chapter 13 (partial repayment plans) cases filed for five consecutive weeks in early 2007, and selected 1000 cases per week for detailed study. The researchers collected data from a) the petitions filed by the debtors, which contain enormous detail about their financial condition; b) other court records; c) questionnaires from about half of the cases; and d) interviews of about 20% of the filers. That is a wonderful cross-section of Americans whose finances were destroyed just before the Great Crash.
