Fairness Without Demographic Data: A Survey of Approaches

Open access
Ashurst, Carolyn, Weller, Adrian·2023·Equity and Access in Algorithms, Mechanisms, and Optimization

Abstract

Detecting, measuring and mitigating various measures of unfairness are core aims of algorithmic fairness research. However, the most prominent approaches require access to individual level demographic information, such as sex or race. In practice, such information is often inaccurate, incomplete or entirely absent. A wealth of techniques have been proposed in response, such as proxies, trusted third parties and cryptographic solutions. These vary greatly in their assumptions, aims and costs, making it challenging to ascertain which methods might be appropriate for a given setting. We aim to clarify the landscape by providing an overview of the different proposals, surfacing the key dimensions in which they differ, and briefly discussing associated benefits, limitations and ethical considerations. We hope this will be of benefit to researchers, practitioners and regulators attempting to navigate this space.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Algorithms can be biased even in the absence of demographic data, particularly through proxy discrimination, where a set of attributes acts as a proxy for the protected attribute.

    “Algorithms can be biased even in the absence of demographic data, particularly through proxy discrimination, where a set of attributes acts as a proxy for the protected attribute (Ashurst and Weller, 2023).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
