The San Francisco Chronicle notes that it is difficult to keep track of foreclosure rates now … let alone during the Great Depression:
Foreclosure rates of the late 2000s are often compared with those of the Great Depression, which took place through the first half of the 1930s. However, there were no public or private agencies keeping track of foreclosure rates at that time. Indeed, the government still does not keep an official statistic on the number of homes in foreclosure or repossessed by banks and lenders.
But the Chronicle provides estimates of foreclosures during the 1930s:
A 2008 article by David C. Wheelock, an economist at the Federal Reserve Bank of St. Louis, cited annual reports issued by the Federal Home Loan Bank Board during the 1930s. These reports reveal that the foreclosure rate exceeded 1 percent from 1931 until 1935. At the worst point in the Depression-era economic crisis, in 1933, about 1,000 home loans were being placed in foreclosure by banks every day.
Approximately 1.4 million homes, or 3.4 percent of all homes with a mortgage, were in the national foreclosure inventory as of May 2012 compared to 1.5 million, or 3.5 percent, in May 2011 and 1.4 million, or 3.4 percent, in April 2012. The foreclosure inventory is the share of all mortgaged homes in some stage of the foreclosure process.
Given that there are currently around 316 million Americans – more than twice the number during the Great Depression – such high foreclosure rates mean that there may well be as many people suffering foreclosure than during the Great Depression … or more.
Already some 5 million homes have been lost to foreclosure; estimates of future foreclosures range widely. [Moody's Analytics chief economist Mark Zandi], who has followed the mortgage mess since the housing market began to crack in 2006, figures foreclosures will strike another three million homes in the next three or four years.
