Diversity
"Diversity can be defined as the sum of the ways that people are both alike and different. Visible diversity is generally those attributes or characteristics that are external. However, diversity goes beyond the external to internal characteristics that we choose to define as ‘invisible’ diversity. Invisible diversity includes those characteristics and attributes that are not readily seen. When we recognize, value, and embrace diversity, we are recognizing, valuing, and embracing the uniqueness of each individual. (Adapted from National Education Association)"
Equity
"Equity is not the same as formal equality. Formal equality implies sameness. Equity, on the other hand, assumes difference and takes difference into account to ensure a fair process and, ultimately, a fair (or equitable) outcome. Equity recognizes that some groups were (and are) disadvantaged in accessing educational and employment opportunities and are, therefore, underrepresented or marginalized in many organizations and institutions. The effects of that exclusion often linger systemically within organizational policies, practices, and procedures. Equity, therefore, means increasing diversity by ameliorating conditions of disadvantaged groups. (Adapted from National Association of Social Workers)"
Inclusion
"Inclusion means an environment in which all individuals are treated fairly and respectfully; are valued for their distinctive skills, experiences, and perspectives; have equal access to resources and opportunities; and can contribute fully to the organization’s success." (Adapted from Society for Human Resources Management, Hewlett Packard, and Ferris State University)
Adopted by ALA Council in 2017 per the recommendation of the ALA Task Force on Equity, Diversity, and Inclusion.
