June 2014 the FAA was still quoting "More than 25 percent of general aviation fatal accidents occur during the maneuvering phase of flight — turning, climbing, or descending close to the ground. The vast majority of these accidents involve stall/spin scenarios (half of which are while in the traffic pattern) and buzzing attempts." Sorry, can't be of more help.
Edit to add: Since January 2001 to Nov 2003 there have been more than 80 stall/spin accidents in general aviation in the United States. And last year, Pat Veillette, an instructor in the personnel training department of a major air carrier, did a formal study of the NTSB’s records and found that between 1994 and 2000, there were 394 spin-related accidents in this country. Fatal accidents numbered 324.
