The Millennium Cohort Family Study Launches New Survey

Military Spouses Will Be Invited This Year to Join the Landmark Study

Both the Millennium Cohort Study and the Millennium Cohort Family Study are inviting new participants to join these unique studies, which are the largest long-term surveys of service members and their spouses. Spouses who are invited to take part in the family study will have the opportunity to share their perspectives of the impact of military life on their careers, stress, well-being, health, and adjustment.

Originally started in 2011 as a companion to the Millennium Cohort Study of military service members, the Department of Defense-sponsored Millennium Cohort Family Study is the only DOD-wide research program examining the effects of a military career on the health of military spouses.

Together, both studies have produced important new information regarding the mental and physical health of service members and their spouses. Program success relies on the work of a broad coalition of researchers led by the Naval Health Research Center, in collaboration with Uniformed Services University, the Department of Veterans Affairs, and multiple civilian academic and private research organizations. Furthermore, this project only succeeds with the voluntary support of the thousands of service members and their spouses who participate.

Results from these studies are used to inform policy and programs targeting military service members and their families. For more information on the Millennium Cohort Family Study visit Further information about enrollment for the Millennium Cohort Study is also available at
