The morphological characteristics of a city have a direct relationship with the human activities happening in the public spaces. If, however, the public spaces become unsafe, people may avoid them. On the other hand, safe public spaces allow free movement for everyone, which is the most basic human need and a crucial part of social sustainability. By focusing on the present-day realities that create the link between the implications for ownership and the provision of the public spaces, this research aims to understand the nature of the morphological characteristics of cities in the Global North and South and its impact on and association with fear of crime. Two case study streets in Stockholm, Sweden, and Karachi, Pakistan, are selected to establish a hypothesis. The study draws upon comprehensive data through a questionnaire survey and morphological analysis. The results suggest that the selected streets in the Global North and South show a similar morphological structure in terms of street layout, land use, plot patterns, and heights of the buildings but difference in pedestrian flows. In relation to the fear of crime, both streets show parks as risky places to visit at night. The results also show some differences in terms of people's responses to the fear of crime in relation to the city's morphology. For instance, people avoid vacant plots and petrol pumps in Karachi, while entrances to metro stations and hidden corners of buildings are considered risky places in Stockholm.
