According to the U.S. Consumer Product Safety Commission, there were
64,219 injuries in 2002 related to "2-wheeled, powered, off-road
vehisle", otherwise known as dirtbikes. Of these, 3,683 injuries were
serious enough to require hospitalization. There were no reports of
fatalities in the CPSC database.
CPSC operates the "National Electronic Injury Surveillance System"
which is available online at:
At the bottom of the page is a button to "QUERY NEISS". Pressing this
will take you to a query page where you can specify many different
types of data: what caused the
injury (in your case, Product Code 5036 -- TWO-WHEELED, POWERED,
OFF-ROAD VEHICLES), how serious was the injury (fatal, needing
hospitalization, etc), what part of the body was injured (head, arms,
etc), and where did the injury occur (home, school, farm, etc).
Running a query gives you a simple numerical result:

A separate query gave me:

Note, too, that you can access individual case reports that look like this:

It's a powerful system, but also takes a bit of playing around with to
become familiar with its capabilities.
So go ahead and play.
