As America’s mortgage markets began unraveling this year, economists seeking explanations pointed to “subprime” mortgages issued to low-income, minority and urban borrowers. But an analysis of more than 130 million home loans made over the past decade reveals that risky mortgages were made in nearly every corner of the nation, from small towns in the middle of nowhere to inner cities to affluent suburbs, the Wall Street Journal reports.

The analysis of loan data by The Wall Street Journal indicates that from 2004 to 2006, when home prices peaked in many parts of the country, more than 2,500 banks, thrifts, credit unions and mortgage companies made a combined $1.5 trillion in high-interest-rate loans. Most subprime loans, which are extended to borrowers with sketchy credit or stretched finances, fall into this basket.

High-rate mortgages accounted for 29% of the total number of home loans originated last year, up from 16% in 2004. About 10.3 million high-rate loans were made in the past three years, out of a total of 43.6 million mortgages. High-rate lending jumped by an even larger percentage in 68 metropolitan areas, from Lewiston, Maine, to Ocala, Fla., to Tacoma, Wash.

To examine the surge in subprime lending, the Journal analyzed more than 250 million records on mortgage applications and originations filed by lenders under the federal Home Mortgage Disclosure Act. Subprime mortgages were initially aimed at lower-income consumers with spotty credit. But the data contradict the conventional wisdom that subprime borrowers are overwhelmingly low-income residents of inner cities. Although the concentration of high-rate loans is higher in poorer communities, the numbers show that high-rate lending also rose sharply in middle-class and wealthier communities.
