Note. The sample of 205,566 person-months includes all 21,740 regular Army soldiers (i.e., excluding those in the U.S. Army National Guard and Army Reserve) with a suicide attempt, suspicious injury, or suicide ideation in the administrative records during the years 2004–2009 plus a 1:200 stratified probability sample of all other active-duty regular Army person-months in the population exclusive of cases (i.e., soldiers with a suicide attempt, suspicious injury, or suicide ideation) and person-months associated with death (i.e., suicides, combat deaths, homicides, and deaths due to other injuries or illnesses). All records in the 1:200 sample were assigned a weight of 200 to adjust for the undersampling of months not associated with suicide attempt, suspicious injury, or suicide ideation.
Rate per 100,000 person-years.
n1 = number of soldiers with a suicide attempt, suspicious injury, or suicide ideation; n2 = number of person-years, not person-months, in thousands in the population. As noted previously, the 205,566 person-months in the sample represent a 1:200 sample of the 37.0 million person-months (3.08 million person-years) in the population of regular Army soldiers (i.e., excluding those in the U.S. Army National Guard and Army Reserve) on active duty for one or more months in calendar years 2004–2009.
Includes general educational development (GED) credential and alternative education.
