Recent advancements have made significant progress in addressing fair ranking and fairness with
continuous sensitive attributes as separate challenges. However, their intersection remains underexplored,
although crucial for guaranteeing a wider applicability of fairness requirements. In many real-world
contexts, sensitive attributes such as age, weight, income, or degree of disability are measured on a
continuous scale rather than in discrete categories. Addressing the continuous nature of these attributes
is essential for ensuring effective fairness in such scenarios. This work aims to fill the gap in the existing
literature by proposing a novel methodology that integrates state-of-the-art techniques to address long-
term fairness in the presence of continuous protected attributes. We demonstrate the effectiveness and
flexibility of our approach using real-world data.
