DEI Meaning: What Diversity, Equity and Inclusion Stand For

DEI meaning, letter by letter

For a working DEI definition, and the full meaning of DEI as most offices use it, take each letter in turn.

• D for diversity: having people of different backgrounds in a group, such as differences in race, ethnicity, gender, age, religion, disability, class, region or way of thinking.
• E for equity: fairness in process and outcome, which may mean giving different support to people who start from different places. This is different from equality, which means the same treatment for everyone.
• I for inclusion: making sure people who are present can take part fully, be heard and feel they belong.

People who use the term often say diversity is about who is in the room, while inclusion is about whether they get a real say once there.

What DEI programs actually do

The details vary a lot from one organization to another. Typical DEI activity includes:

• Reviewing hiring and promotion steps to remove bias, for example by using structured interviews or removing names from early screening
• Training staff on topics such as harassment, unconscious bias or respectful communication
• Checking pay for unexplained gaps between groups
• Making buildings, websites and documents accessible to disabled people
• Supporting employee groups, mentoring schemes and flexible work
• Publishing data on staff makeup

Where the term came from

The ideas behind DEI grew from older efforts against discrimination. In the United States, civil rights laws of the 1960s banned job discrimination based on race, color, religion, sex and national origin, and some employers adopted affirmative action plans. In the 1980s and 1990s, "diversity" training and "diversity management" spread in large companies. "Inclusion" was added to stress belonging, and "equity" later still. The three-letter DEI spread fast within roughly the last decade, as many organizations created DEI roles and offices. Other countries use similar labels; in the UK, EDI is often preferred.

Why DEI is debated

Few workplace terms divide opinion as sharply. The main arguments, stated as each side puts them:

In the United States, debate has led to legal and policy changes. Several states have passed laws limiting DEI offices or training at public colleges, federal policy has moved to end many DEI programs in government, and some companies have cut or renamed their programs while others have kept them. Words linked to this debate, such as woke and privilege, have their own pages.

DEI in sentences

• The university's DEI office runs workshops on accessible teaching.
• Our team lead asked whether the new hiring rubric had a DEI review.
• The firm's annual report includes a short section on DEI goals.
• Some companies now describe the same work as inclusion or belonging rather than DEI.

Note that DEI is usually written in capitals and works like a noun or an adjective: a DEI officer, DEI policies, spending on DEI.

Dei in Latin: a different word

Not every "dei" is the acronym. In Latin, Dei means "of God". It appears in phrases you may meet in religious music, mottos and old coins: Agnus Dei (Lamb of God), Dei gratia (by the grace of God) and Deo forms such as Deo gratias (thanks be to God). In this sense it is pronounced roughly DAY-ee and written with a small or capital D, never as three capital letters. Related religious terms are explained on our deity page.

Legal background in brief

DEI programs sit alongside, but are not the same as, anti-discrimination law. Laws in many countries forbid treating workers or students worse because of protected traits. DEI goes further by encouraging steps to widen access. Courts and lawmakers continue to decide where the line falls between lawful outreach and unlawful preference, and the rules differ by country and change over time. Neighboring terms appear among our law, politics and society entries.
