The stats prove several things:
a) PPLs who do not continue training are the most likely to come a cropper
b) PPLs who continue beyone PPL level by adding further training (Aero's, IR, CPL etc..) are less likely to come a cropper
c) EF's in SEPs don't kill an awful lot of people
d) IFR at night is no more dangerous than VFR at night, but may be safer depending on where you are flying (i.e. proper IFR, not mickeymouse IFR)
e) IFR is safer than VFR (else all 777's would fly VFR)
f) Pilots of Twins, although less likely to be involved in an accident are more likely to be killed if they do.
g) MOST accidents are pilot error (75%+), or are contributed to be pilot error.
So the conclusion is: Keep training, add new ratings every few years, and be the best you can and don't take silly risks (while aero's is completely safe, what kills people is the bloke who thinks "oh I'll just do a low fly past and do a roll for my wife and kids".....)
By the way, the NTSB publish their stats so anyone can read them....
