At JURSE 2025 in Tunisia, the DEPRIMAP team presented new research on scalable urban deprivation mapping using open geospatial datasets. The study, rooted in collaboration from the 2024 Switzerland workshop, showcased a composite deprivation score framework tested in Nairobi and validated across eight global cities. The presentation introduced extended cross-city comparisons and laid out future directions, including new indicators, refined thresholds, and open-source tools.
