How do I decide if demographic parity is appropriate for my use case?

Asked on Oct 12, 2025

Answer

Determining if demographic parity is appropriate for your use case involves assessing the fairness goals and potential impacts of your AI system. Demographic parity, a fairness metric, ensures that each demographic group receives positive outcomes at equal rates, but it may not suit every context due to trade-offs with other fairness measures like equal opportunity.

Example Concept: Demographic parity is suitable when the goal is to ensure equal treatment across groups regardless of their inherent differences. It is often applied in contexts where the decision-making process should not be influenced by sensitive attributes, such as loan approvals or hiring. However, it may not be appropriate if the underlying base rates of positive outcomes differ significantly across groups, as this could lead to unintended biases or reduced accuracy.

Additional Comment:

Consider the societal and ethical implications of enforcing demographic parity in your specific use case.
Evaluate the trade-offs between fairness and accuracy, and whether other fairness metrics like equal opportunity might be more suitable.
Review existing frameworks and guidelines, such as the NIST AI Risk Management Framework, for insights on fairness metric selection.
Consult stakeholders to understand the impact of demographic parity on all affected groups.
