European armed forces still remain predominantly white, male organizations; their societies, however, are becoming more diverse and older. How will these armed forces be able to cope with this challenge? In order to answer this question, in the first semester of 2017, a group of scholars working within the framework of the European Defense Agency conducted an online survey among international experts in human and social sciences, defense managers, policymakers, and journalists specialized in defense issues. The aim of the survey, which followed a previous survey among young people on the attractiveness of the military as a job, was to measure their opinions and ask their suggestions concerning possible ways for increasing diversity in European armed forces. This paper presents some of the results of this multinational online survey.The unique feature of the study is that it is forward-looking and international: experts from various NATO and EU countries were asked how Defense organizations could deal with future challenges of demographic characteristics. The study, therefore, adds to our understanding of possible solutions for ensuring increased diversity in armed forces.
