The aim of this essay is to define and describe the different constituents of the military population, and present the challenges this demographic faces when pursuing higher education. The essay also discusses key aspects higher education professionals must understand in order to better serve military populations, such as federal regulations and military structures. After reviewing several reports from the government and organizations that support military populations, the authors found more research is needed in order to better understand the unique challenges of civilian male spouses of active duty service members, and both male and female spouses of disabled veterans and military retirees, as research and reports have historically excluded these populations. The authors conclude by presenting best practices higher education institutions can put into practice to better serve military populations.
