Nations of different urbanization styles under different scenarios are likely to experience different urban expansion rate trajectories (high, medium, or low) within their respective uncertainty ranges generated by Monte Carlo simulations. SSPs 1–5: sustainability, middle of the road, regional rivalry, inequality, fossil-fueled development.
