"In this issue paper, we present a consistent demographic profile of the active-duty enlisted corps across the five Services. We separate personnel in ranks E1-E6 from those in ranks E7-E9, and we display the data in charts and tables by gender and race/ethnicity categories. Data are reported as percentages and as raw counts to facilitate comparisons and illustrate differences in magnitude. Although the data presented here are in the form of 2008 snapshots, we also provide an appendix with yearly data starting in 2000."
