"In the military's closed personnel system, the demographic diversity of leadership depends largely on the relative career progression rates of members of each demographic group: If women and racial and ethnic minorities advance at lower rates than white men, they will not be represented in the top ranks. Career progression in the military has two components: rates of retention to each promotion window and rates of promotion to each pay grade. To explore the role that retention rates play in determining the demographic profiles of senior leadership, the Military Leadership Diversity Commission (MLDC) created a subcommittee tasked with determining whether there are racial, ethnic, and gender differences in retention rates, and, if so, why such differences exist. The goal of this decision paper is to provide an overview of the subcommittee's findings and to show how they support the Commission's final recommendations related to retention."
