numbers can lead you astray. How many were in Theater; how many elsewhere in the world. How many in CONUS. Any combat tours? If so, how many? Where? What was the catalyst? Spousal problems? Money problems? Stress? Combat stress or other stress? How many male? How many Female?

IIRC, the current rate is still lower than the 19-25 non-military demographic in the US for males but higher for females. I also seem to recall reading somewhere that the in theater rate was lower than anyone expected and the majority were not in the two theaters.

Without detailed info, the raw number is borderline meaningless. The fact that it's the highest in 20 years is at least partly due to the fact that as a result of the surge the active duty end strength is higher than it has been in 20 years...

* That similarity is from memory (and I'm old, so it may be flaky). Not an issue to me but Google may be able to provide definitive numbers of a sort.
