A new study reveals that medieval cities in Western Europe had statistically indistinguishable community grouping patterns compared to younger European cities. The research suggests that social dynamics enabled by medieval cities were fundamentally similar to those of contemporary cities.
A new study suggests that squatters can have a positive impact on neighborhoods. Residents often welcome responsible squatters to occupy abandoned homes, as it helps maintain the property and reduces crime. In urban areas with population decline, squatters can help bring about improved neighborhood conditions.
