DEI Categories in the Workplace: 6 Lesser-Known Areas to Consider

When organizations think about DEI categories in the workplace, the focus often centers on race and gender. While those dimensions are critically important, they don’t capture the full range of differences that shape how employees experience work. DEI encompasses not only race and gender, but also different races, ethnic diversity, gender diversity, socioeconomic background, and the formation of diverse teams, all of which are essential for fostering an inclusive and equitable workplace.

Employees bring diverse abilities, backgrounds, health needs, thinking styles, and communication preferences into the workplace. When these factors are overlooked, even well-intentioned DEI programs can fall short, unintentionally excluding talent and limiting engagement.

This article explores six lesser-known DEI categories in the workplace and explains how expanding your inclusion strategy can lead to stronger culture, better collaboration, and more equitable outcomes. Organizations that prioritize DEI can better attract and retain top talent.

Introduction to Diversity in the Workplace

Diversity in the workplace is more than just a buzzword—it’s a strategic advantage that shapes the success and sustainability of modern organizations. By bringing together individuals from a wide range of backgrounds, experiences, and perspectives, companies can unlock innovative ideas, foster better decision-making, and drive higher levels of employee engagement. A truly diverse workplace goes beyond surface-level differences, embracing internal diversity (such as age, gender, and physical ability), external diversity (including cultural background and life experiences), organizational diversity (like job function and seniority), and worldview diversity (encompassing personal morals, beliefs, and perspectives).

When organizations prioritize diversity, equity, and inclusion, they create a more inclusive environment where all employees feel valued and empowered to contribute. This not only enhances organizational diversity but also helps attract and retain top talent in a competitive market. By understanding and embracing the many types of diversity in the workplace, companies can build a culture that supports innovation, collaboration, and long-term business growth—ensuring that every employee has the opportunity to thrive.

Why DEI Categories in the Workplace Must Go Beyond the Obvious

True inclusion requires looking beyond visible or commonly discussed traits. People work, learn, and communicate in different ways, and one-size-fits-all policies can create barriers for employees who don’t fit a narrow definition of “typical.”

Organizations that broaden how they define DEI are better positioned to support innovation, reduce risk, and build trust across their workforce. Diversity efforts are increasingly important to job seekers, as many consider workplace diversity a key factor when evaluating job opportunities.

Expanding DEI categories in the workplace helps ensure policies, practices, and expectations reflect how people actually work. A commitment to DEI can enhance a company's reputation and attract more job applicants.

1. Physical Ability as a DEI Category in the Workplace

Physical diversity includes a wide range of differences that affect how employees interact with their environment, such as:

• Vision or hearing impairments
• Mobility limitations
• Physical characteristics such as mobility, vision, or other visible and invisible traits

Inclusive workplaces proactively consider physical ability when designing offices, planning events, and selecting tools. This includes thinking ahead about accessibility, not just responding after challenges arise.

When physical ability is treated as a core DEI category in the workplace, organizations reduce barriers and demonstrate respect for all employees.

2. Health Conditions and Invisible Diversity

Health diversity is often overlooked because it isn’t always visible and doesn’t always require formal accommodation.

Examples include:

• Chronic illnesses
• Allergies or sensitivities
• Pregnancy and post-partum recovery 

Organizations that recognize health conditions as part of DEI categories in the workplace often focus on flexibility — such as adjusted schedules, remote options, or workload modifications — allowing employees to perform at their best without stigma.

3. Educational Background, Socioeconomic Diversity, and Access

Educational diversity extends beyond degrees and credentials. Employees with similar qualifications may have vastly different educational experiences, influencing:

• Learning styles
• Confidence in professional settings
• Access to networks and mentorship 

Over-emphasizing institutional prestige or relying heavily on referrals can unintentionally exclude capable candidates. Inclusive organizations recognize educational background as a DEI category in the workplace and prioritize skills, growth potential, and performance.

4. Cognitive Diversity in the Workplace

Cognitive diversity refers to differences in how people think, learn, and solve problems.

This includes:

• Learning styles (visual, auditory, kinesthetic)
• Work styles (detail-oriented, conceptual, collaborative)
• Neurodiversity, such as ADHD or autism
• Diverse personalities, which encompass a variety of individual traits and thinking styles

When cognitive diversity is treated as a core DEI category in the workplace, managers adapt communication, feedback, and task design, unlocking creativity and improving decision-making across teams.

Diverse teams are more effective at problem-solving and decision-making.

5. Age as a Dimension of DEI

Age diversity brings a wide range of experiences, perspectives, and working styles into an organization.

Inclusive workplaces:

• Avoid stereotypes about age
• Recognize that needs vary within age groups
• Encourage cross-generational collaboration 

Pairing employees of different generations supports knowledge sharing, mentorship, and stronger interpersonal connections, all of which strengthen workplace culture.

6. Language Diversity and Communication

Language diversity is a critical yet often underestimated DEI category in the workplace.

This can include:

• Employees whose first language is not English
• Employees who speak different languages, dialects, or have distinct accents
• Multilingual teams
• Different communication styles influenced by culture

Inclusive practices may involve translating key materials, simplifying internal communications, and ensuring language differences do not limit access to information, advancement, or participation.

Internal Diversity Considerations

Internal diversity refers to the inherent characteristics that individuals are born with or develop over time, such as race, age, gender, physical abilities, and sexual orientation. These aspects of diversity are often the most visible and can significantly influence how employees experience the workplace. Recognizing and supporting internal diversity is essential for building a truly inclusive workforce, as it ensures that underrepresented groups are not only present but also have equal opportunities to succeed.

Organizations that prioritize internal diversity take deliberate steps to create an environment where all employees feel valued, respected, and included. This can involve implementing inclusive hiring practices, supporting employee resource groups, and offering mentorship programs that help diverse employees advance in their careers. By addressing internal diversity, companies can reduce barriers, promote workplace equity, and foster a culture where everyone is treated fairly, laying the foundation for broader diversity initiatives and a more engaged, innovative workforce.

Fostering an Inclusive Workplace Culture

Creating an inclusive workplace culture is about more than just policies—it’s about embedding inclusion into every aspect of organizational life. An inclusive culture ensures that all employees, regardless of their background or identity, feel welcomed, respected, and empowered to share their perspectives. This kind of environment not only supports organizational diversity but also drives better business outcomes by harnessing the full potential of a diverse workforce.

To foster an inclusive workplace, organizations should invest in DEI training and unconscious bias training, establish clear anti-discrimination policies, and hold leaders accountable for promoting inclusion. Encouraging open communication, providing regular feedback, and celebrating different cultures and perspectives can help build trust and strengthen employee engagement. Additionally, offering flexible work arrangements and supporting mental health and well-being initiatives can make the workplace more accessible to everyone. By making inclusion a core value, companies can create a culture where employees are treated fairly, workplace discrimination is minimized, and everyone has the opportunity to contribute to the organization’s success.

Turning DEI Categories into Action for an Inclusive Workplace

Recognizing DEI categories in the workplace is only the first step. Inclusion requires intentional action, such as:

• Considering physical and cognitive diversity when planning activities
• Offering flexibility for health-related needs
• Broadening hiring and promotion criteria
• Encouraging managers to adapt communication styles
• Making internal materials accessible and inclusive
• Supporting employees by addressing their diverse needs, such as providing mentorship, financial assistance, and accommodations for different socioeconomic backgrounds and cognitive disabilities

These actions transform DEI from a concept into a lived experience.

Embracing multiple perspectives—by valuing diverse backgrounds, skills, and experiences—drives innovation and collaboration. Fostering a culture where it's okay to speak up helps move the organization forward. Diverse employees bring different skills, talents, and lived experiences to their work, boosting creativity and innovation.

Conclusion

Expanding your understanding of DEI categories in the workplace is essential for building a truly inclusive and high-performing organization. By looking beyond the obvious and embracing lesser-known aspects of diversity, companies can create a more equitable environment where all employees feel valued and supported. A holistic approach to diversity, equity, and inclusion not only reduces risk and enhances compliance but also drives innovation, employee engagement, and better business outcomes.

As the workforce continues to evolve, organizations must remain committed to fostering diversity in the workplace and continuously evaluating their DEI initiatives. By doing so, they can ensure that every employee—regardless of background, ability, or perspective—has the opportunity to thrive and contribute to a stronger, more resilient company culture. For equitable management, it's also important to use proper documentation for workplace issues to address misconduct consistently and fairly.

Frequently Asked Questions (FAQ)

What are DEI categories in the workplace?

Why should DEI go beyond race and gender?

While race and gender are essential components of DEI, employees experience inclusion in many ways. Expanding DEI categories helps organizations reduce barriers, improve engagement, and create more equitable workplaces.

How does cognitive diversity support inclusion?

Cognitive diversity introduces different ways of thinking and problem-solving, improving creativity and innovation when managers adapt communication and expectations.

How can leaders support broader DEI categories?

Leaders can support inclusion by avoiding assumptions, offering flexibility, adapting communication styles, and enforcing policies consistently across all teams.

How can organizations track progress on DEI?

Using structured tools and processes to document concerns, monitor trends, and follow up on issues helps organizations move from intention to measurable inclusion outcomes. The Equal Employment Opportunity Commission (EEOC) plays a key role in overseeing DEI compliance and ensuring organizations meet legal requirements. Companies with diverse teams outperform those without diversity initiatives and have financial returns above their respective national industry medians. In fact, diverse companies are 35% more likely to record financial returns above the industry median.
