Overall suicides in the U.S. military were down just under 10% in 2013 over the year before, although there was slight increase (5%) among reservists and those not on active duty, new data from the Department of Defense shows.

With the wind-down in Afghanistan well under way, the gap between casualties and suicides grew even more dramatically, now nearly 4-1 vs. just under 2-1 the year before. (See chart below).

The data was part of the extensive annual “Suicide Event Report” that is put together by the National Center for Telehealth & Technology. The latest report covered calendar year 2012, while a news release about the report include top-level data for 2013. (Access a PDF of that report and earlier years back to 2008 here).

The U.S. Army halted what had been monthly updates of its suicide data after November data was posted in December. Reports suggest the Army is changing its methodology and will move to a quarterly instead of monthly release.

The Marines and Navy have, and continue to, release data each month, often updating the earlier month’s data. In 2013, Navy and Marine suicides fell, while attempted suicides by Marines jumped, based on the monthly data release.

For the Army in 2013, total suicides were on the decline but the percentage that were reservists had increased as a percentage of all suicides, from 40% to 50%. That data does not include December statistics, which have yet to be released.
