About the DiversityInc Top 50

The DiversityInc Top 50 Companies for Diversity competition is an editorial, objective process, obtained through a detailed, analytic survey of more than 200 questions. The overall intent is not just to track metrics but to draw an accurate picture of a company’s culture.

Last year, more than 401 companies participated, and we anticipate an increase in that number this year. The survey is sent to any company requesting it that has more than 1,000 employees. There is no fee to enter and no requirement to advertise.

Companies are assessed within the context of their industries and employee skill sets. The questions have predetermined weightings and are evaluated based on ratios of certain questions, such as work-force demographics compared with new-hire demographics, and relativity of one subject to another, such as mentoring best practices and management promotions.
