The 2019 Workplace and Equal Opportunity Survey of Reserve Component Members (2019 WEOR) fulfills the Congressional mandate outlined in Title 10 USC §481 for a quadrennial survey to assess racial/ethnic relations in the military. The 2019 WEOR was the fourth Reserve component survey conducted to meet this statutory requirement. The survey was designed to assess self-reported experiences of, the climate surrounding, reporting, and policy effectiveness at preventing racial/ethnic harassment and discrimination in the military. The purpose of this executive report is to summarize the statistical and survey methodology employed on the survey, illustrate how estimates of past year racial/ethnic harassment and discrimination rates were constructed, and provide topline findings. Results are reported by race/ethnicity for the DoD overall, and then separately for each Reserve component.
