Wikipedia: Over 90% of Polish Jews were killed, and about 75% of German Jews.
Until I checked, I didn't realize that the proportion of German Jews who were killed was that high. I didn't have a specific number in mind, I think I was just giving more attention to the idea of those who'd escaped.
Oh, and the difference between people that flew at a suitable time vs. the number of people who survived. The later includes people who were deported but not killed, so the former is even lower. If you haven't read it yet. I found the comic from Art Spiegelman called 'MAUS!' pretty intense and interesting.
