Diversity, equity and inclusion is a framework that promotes a set of values and related policies and practices that focus on creating fair and welcoming environment for all individuals, particularly groups that have historically been underrepresented or marginalized.
The concept of DEI has roots that trace back to the mid-20th century during the Civil Rights Movement, and many DEI supporters see the U.S. Civil Rights Act of 1964 as a catalyst for the modern push for diversity, equity and inclusion efforts.
