Diversity surveys: How to make diversity in the company measurable

To strengthen diversity, equity, inclusion, and belonging in your company, you need reliable data on the actual diversity of your workforce and the culture lived within the organization. A professionally designed diversity survey is one of the most effective tools for this. It reveals how employees experience a sense of belonging, where barriers exist, and where improvements are needed. Such a survey also demonstrates to the workforce that equal opportunity and diversity are taken seriously within the company.  

For a survey to yield valid results, the methodology, data protection, and communication must be well thought out. And for the results to be translated into effective measures, the survey must be strategically integrated. The following short guide provides practical tips on what organizations should consider when conducting and implementing their diversity surveys.

1. The right survey: Methodology, topics, and measurable KPIs

Depending on the objectives and focus, a diversity survey can be conducted as a standardized online survey, personal interviews, or a combination of both.

Overview of methods:

• Quantitative online surveys: provide reliable results for the entire sample and are efficient to implement.
• Qualitative interviews or focus groups: provide deeper insights into individual experiences and offer context for interpreting the numbers.

Questions should be clearly formulated, inclusive of all employees, and asked without assumptions. Demographic information should be voluntary and collected in sufficiently broad categories to prevent the identification of individuals. Questions regarding a sense of belonging, appreciation, equal opportunity, or experiences with discrimination have proven effective. Topics such as corporate culture, openness to diversity, barriers in everyday work, work-life balance, and general job satisfaction also provide meaningful insights.

The data collected helps make diversity, equity, inclusion, and belonging measurable and shows where barriers exist or which groups require additional support. Measurable KPIs make the success of diversity, equity, inclusion, and belonging initiatives tangible.

Typical key performance indicators include:

• Representation of different genders at various hierarchical levels
• Perceived equal opportunity, sense of belonging, and engagement scores
• Experienced psychological safety and fairness in development and promotion processes
• Turnover, health, or willingness to recommend, analyzed by diversity dimensions

It is important to view KPIs not in isolation, but within the context of corporate culture, working conditions, and strategic goals. This ensures that diversity surveys align with existing management logic and reports, providing actionable insights.

2. Data protection and anonymization as a fundamental requirement

Much of the data collected in diversity surveys is highly sensitive. Therefore, companies must transparently explain what data is being collected, why it is being collected, and how it is protected. Participation must always remain voluntary.

What to look out for regarding data protection:

• Information and consent: GDPR-compliant processing and prior notification are essential. Information should be clear, understandable, and transparent. Consent for data processing must be obtained before the survey begins.  
• Anonymization: It should not be possible to draw conclusions about individuals. The scaling of questions should be adjusted to the sample size. Particularly vulnerable or small groups must be protected during data collection and evaluation, and sufficiently large groups must be formed for analysis.  
• Data separation: technical separation of identification features and responses. If possible, raw data processing should be handled by an external provider.  
• GDPR-compliant storage and processing: Data should ideally be collected via certified external tools with storage within the EU.  

Working carefully and transparently regarding data protection and anonymization builds trust and improves participation rates.

3. How companies can achieve a high participation rate

A diversity survey is only meaningful if many employees participate. Open, transparent communication that clearly explains the benefits, goals, and data protection is crucial. Employees need to understand why their voice matters. This increases trust and, consequently, participation.  

What to keep in mind:  

• A short, easy-to-understand questionnaire taking no more than 10–15 minutes.
• Mobile accessibility, e.g., for shift workers.
• Reminders at appropriate times and via different channels.
• A sensible survey period and sufficient duration to allow as many people as possible to participate, despite absences and workload.
• Visible support from managers and executive leadership.
• Transparent communication regarding the process, results, and planned follow-up actions.
• Adherence to data protection and anonymization

4. Conduct internally or outsource?

Whether a survey is conducted internally or externally depends on resources and objectives. Internal surveys are flexible and cost-effective, but often face skepticism regarding anonymity. Furthermore, internal teams often lack the necessary methodological expertise.  

External providers offer:

• Maximum possible data anonymity  
• neutral execution without internal bias
• Methodologically sound questionnaires
• Professional and objective analysis
• Overall higher data credibility

Especially when dealing with sensitive topics such as discrimination, workload, barriers, or employee satisfaction at a granular level, external support can significantly increase the chances of success. External providers may also mean higher costs. If the budget does not cover full external management, individual steps (such as questionnaire design) can be supported by professional consulting.  

5. Strategically anchoring diversity surveys

The strategic work begins after the survey: analyzing, interpreting, and implementing the results. To ensure the data doesn't just gather dust, it should be clear before the survey even starts what the next steps will be for working with the findings. Only when the survey is well-integrated both operationally and strategically can the data reach its full potential and lead to measurable improvements within the company.  

Important points for preparing and presenting the results:

• Structure the results: analyze relevant subgroups separately, incorporate existing benchmarks, and identify key areas for action.
• Communicate results transparently: to all participants, including the entire workforce.
• In workshops with managers and other relevant stakeholders: prioritize areas for action, translate findings into concrete measures, and develop an implementation strategy.  

Important for strategic integration:

• Binding commitment and clear responsibilities: Executive management and leadership actively support the implementation and monitoring process, provide resources, and give those responsible clear scope for action.
• Participation of relevant stakeholders: The works council, HR, diversity officers, anti-discrimination offices, and other internal stakeholders are involved early on and on an ongoing basis.
• Continuous development process: Regular follow-up surveys to measure progress, as well as ongoing monitoring of measures to make implementation and successes transparent.  

Conclusion

A diversity employee survey can form an important foundation for a targeted and effective DEIB strategy. It reveals how diverse and inclusive an organization truly is and where there is still room for development. Those who take data protection seriously, communicate transparently, and consistently follow up on the results create the basis for sustainable diversity within the company.
