NLSY79 Military Sample
A military sample of 1,280 individuals was designed to represent the population born January 1, 1957, through December 31, 1961, serving in the military as of September 30, 1978. The inclusion of the military sample allows comparative civilian-military analyses.
In 1985, interviewing of the full military sample ceased. Retained were 201 military respondents randomly selected from the entire military sample. Of these, 51 were cases that would have been selected as part of a random sample of youth including the military, and 150 additional cases were selected to provide a sufficient number of original military sample members to avoid overly large sampling variability for the military sample.

Supplementary Information
-
Persons on active military duty as of September 30, 1978, were sampled from rosters provided by the Department of Defense. No formal screening interview was conducted.
Of the 1,793 military youth selected for interviews, 1,280 or 72 percent were interviewed in 1979. Selection of the military sample was accomplished in two stages. In the first stage, a sample of approximately 200 "military units" was selected. These units were selected with probabilities proportional to the number of persons born in 1957 through 1961 and serving in the military unit as of September 30, 1978.
