Lies, damn lies and statistics

The story about the increase in army suicides in the WaPo .is misleading, and I analyze the numbers at the link.

One, the actual increase in the number of Army suicides is 11 more than last year. And two thirds of those committing suicide are not in Iraq or Afghanistan.

Two, the "high rate" compared to civilians is a misleading statistic.

The rate of suicide for the army is 18/100 000 population
The rate of suicide for males aged 20-29 is 22.
The rate of suicide for women aged 20-29 is 3

And to put things into perspective:
the rate of suicide for physicians is also 18/100 000.
