... • How do trajectories during military service relate to readjustment after service? In this chapter, the committee argues that these types of questions are best approached with longitudinal data, that is, repeated surveys of the same individuals over a period of years.
From page 122...
... Administrative Data The armed forces collect data regarding the backgrounds of applicants and recruits, which provide an overview of the military population. They currently collect data on geographic origin, race, age, test scores, education, and gender.

... In the United States, major national surveys include multiple National Longitudinal Surveys sponsored by the Bureau of Labor Statistics, multiple surveys of school populations sponsored by the Department of Education, the Panel Study of Income Dynamics (PSID) sponsored by the National Science Foundation, the Health and Retirement Study (HRS)

... It is difficult to imagine modern empirical social science without them. Civilian longitudinal surveys are rarely based on simple random samples of the population but usually follow stratified random sampling strategies in order to generate information both about individuals and about the groups of which they are part.

... They have used several of these national longitudinal studies to evaluate outcomes related to the military, though they have assessed such phenomena not during military service but afterward among veterans. Scholars have most often evaluated questions related to military service using the National Longitudinal Surveys' National Longitudinal Survey of Youth 1979 (NLSY79)

... THE MILLENNIUM COHORT STUDY: A LONGITUDINAL SURVEY BASED ON THE MILITARY POPULATION The Department of Defense has been operating a large-scale longitudinal study since 2001, the Millennium Cohort Study (developed in response 2  "The NLSY sample draws disproportionately from the lower end of the income distribution.

... The survey data are linked to multiple administrative datasets, including information from, among many others, medical history, mortality, and deployment data (Smith and Millennium Cohort Study Team, 2009)
From page 128...
... Therefore, the committee advocates the creation of a longitudinal database to store already collected administrative and survey data and to be expanded to include data from the new longitudinal survey described below. The database should capture as wide a range of administrative and survey data as possible, to include, for example, responses from surveys given across the armed services, results of initial testing, individual demographics and biodata, duty rotations, assignments, positions, and performance evaluations.

... These data would enable researchers to compare the characteristics of recruits to those of the larger population as reflected in the Decennial Census, the Current Population Survey, and other civilian longitudinal studies. Such data could then be linked to other administrative records, as well as being linked with the information collected under the survey proposed below.

... Army Research Institute for the Behavioral and Social Sciences and other U.S. military funding agencies should work with project staff of the Millennium Cohort Study and with other relevant parties collect ing survey and administrative data on military personnel to: 1.
From page 131...
... Army Research Institute for the Behavioral and Social Sci ences should establish a working group of experts in survey research, empirical social science, and military subject matter charged with devel opment of a new longitudinal survey strategy to track both individuals and small units over time. In addition to developing the new longitudinal survey, the working group would be charged with assessing the number of times an average active service member has to respond to surveys and, if the number is deemed excessive, suggesting ways to minimize these instances.
