Fortune research partner Great Place to Work compiles this annual list of U.S. companies that create inclusive cultures for women and people of all genders, people of color, LGBTQ people, employees who are Boomers or older, and people who have disabilities. In addition to diversity numbers, the ranking is based on surveys of employees, who rated the level of camaraderie they experience at work, the effectiveness of their leaders, and other factors that inspire trust in an employer.
