  • Summary

  • Spoken (by a human) version of this article.

    In a previous article, we discussed algorithmic fairness, and how seemingly neutral data points can become proxies for protected attributes.

    In this article, we'll explore a concrete example of a proxy used in insurance and banking algorithms: postcodes.

    We've used Australian terminology and data. But the concept will apply to most countries.

    Using Australian Bureau of Statistics (ABS) Census data, it aims to demonstrate how postcodes can serve as hidden proxies for gender, disability status and citizenship.
