The paper investigates how to maintain causal fairness when releasing synthetic data by applying the DECAF framework across nine different synthetic data generators from three families (marginals-based, GAN, and diffusion) and three levels of differential privacy. Experiments on Adult and COMPAS datasets show that the causal diffusion backbone consistently produces the fairest data with fidelity comparable to the marginals tier, while the fairness cuts have minimal impact on downstream classifier performance and do not degrade privacy guarantees.

Machine learning models are increasingly deployed in high-stakes domains, raising concerns about both privacy and fairness. Differential Privacy (DP) has become a gold standard for privacy-preserving data analysis, while fairness-aware mechanisms aim to mitigate discrimination against underrepresented groups.
We revisit the fairness notion of disparate impact for synthetic data generation (SDG), that assesses whether the utility of generated records is the same across sensitive groups. Our approach departs from existing work on fair SDG, that address the problem of correcting for undue biases in the observed distribution, hence redefining SDG as learning a distribution that is not that of the real data.
