Code for the paper "Does residential segregation align with urban barriers?"

This code is used for computing the results of the paper "Does residential segregation align with urban barriers?". <br>This code quantifies the spatial alignment between residential segregation patterns and urban fragmentation across 520 European cities using a Monte Carlo approach. The analysis generates synthetic urban fragmentation patterns using Voronoi tessellation and compares observed spatial overlap against null distributions to test whether urban barriers (railways, motorways, waterways) act as social frontiers more than expected by chance.
