The figure is from 2010 from a VA report:
22 veterans commit suicide each day: VA report - U.S. News
The report notes that while the numbers of veterans who die by suicide each day "has remained relatively stable over the past 12 years," the overall percentage of people who die by suicide in America who are veterans has decreased slightly. The share of all suicides reported as "veterans" on state-issued death certificates was 25 percent in 1999 versus slightly more than 20 percent in 2010, according to VA researchers.
"This provides preliminary evidence that the programs initiated by VA are improving outcomes," read an accompanying "executive summary" signed by Dr. Robert A. Petzel, the VA's under secretary for health. "As long as veterans die by suicide, we must continue to improve and provide even better services and care."
Also Friday, the U.S. Army released its monthly suicide report, offering a preliminary tally for 2012 in that branch: 325 "potential" suicides among active and reserve troops — the highest number in history, Army officials noted. More than 50 of those deaths remain "under investigation," awaiting a final ruling. If that bleak total remains at 325, the toll in 2012 would have risen by 15 percent over 2011 when the Army sustained 283 suicides.
