Mental maps compared to actual spatial behavior using GPS data: A new method for investigating segregation in cities

• Examines spatial and temporal segregation using GPS.
• Examines the relationship between perceived territorial boundaries and actual spatial activity.
• Crossing of boundaries in a divided city.

This article examines the relationship between perceived territorial boundaries and actual spatial activity. The methodology used includes a combination of mental maps and interviews for examining perceptions of territorial boundaries, with tracking technology (GPS) and activity diaries to track the actual use of space. This methodology was implemented in a pilot study with a sample of 18 women living in Jerusalem, including secular Jews, ultra-orthodox Jews, and Palestinian Muslims.The study found a very strong relationship between perceived personal territory and actual spatial activity. However, while the secular Jewish women appeared to be completely segregated within their territory, the ultra-orthodox Jewish women and the Palestinian Muslim women were both very active within the secular Jewish territory, but avoided each other’s territories. The analysis of mental maps and actual spatial patterns of residential daily activities challenges prevailing notions about the spatial structure of Jerusalem and the internal power relations between the populations that inhabit it. More generally, it provides a new methodological approach for investigating segregation in cities.
