I just got this information from the Bicycle Helmet web site, concerning statistics on bicycling:
The following facts are based on analysis of data from the U.S. Department of Transportation's Fatality Analysis Reporting System:
--687 bicyclists were killed in crashes with motor vehicles in 2000. This is 8 percent fewer than in 1999 and down 32 percent since 1975.
--Bicycle deaths are most likely to occur in summer. Deaths are most likely to occur on Fridays. The peak time is 3-9 pm.
--Ninety percent of bicyclists killed in 2000 reportedly weren't wearing helmets.
I'll post the web site later, when I can again access it without messing up my work.
