Skydiving in the US is about 7 micromorts per jump. Which in turn is about the same as 1600 miles in a car.
Which I guess means, it depends on how far from the dropzone you live
[edit to add: the average per day in the UK (I know, not the US) is about 39-41, depending on how you count. So a day of jumping doubles your risk (compared to a non jumper, all other factors being equal) of sudden death when it reaches five or six jumps. Interesting eh?]
