[R. Scott]

…there were 61 unprovoked shark attacks around the world in 2004; seven of these resulted in fatalities.

Silly? Out of the literally millions of people in the water, 61 were bit and 7 (seven!) died. I think I was pretty safe.

I think it is like anything else. These numbers are people who were worth reporting. I bet many shark attacks and deaths simply go unreported or at least don't get beyond the victim's village.
