How dangerous/safe are track days and autocross? Are there any stats?

Hi everyone,
I recently had my first track day with my new civic type R and it was really fun. Scary at first I admit but as the laps accumulated I felt more confident and at the end it was a very nice experience. I would very much want to do it again but then it hit me, cars driving fast together, near the edge of their capabilities, things can happen. And I have kids, It's not only a risk for me. Of course there are plenty of anecdotal experiences but they don't necessarily represent the full reality of things. I tried looking for accident or injury statistics to try and make a more sensible decision, but couldn't find any. Of course armature race tracking is less dangerous than competitive race driving such as NASCAR. But how does it compare to say driving on a regular road? Are there any stats on this issue?
