A Relational Model of Neighborhood Mobility: The Role of Amenities and Cultural Alignment

Why are some neighborhoods strongly connected while others remain isolated? Although standard explanations focus on demographics, economics, and geography, movement across the city may also depend on cultural styles and amenity mix. This study proposes a relational, cross-national model in which local culture and amenity mix alignment creates a “soft infrastructure” of urban mobility, i.e., symbolic cues and functional features that shape expectations about the character of places. Using ~650 million Google Places reviews to measure co-visitation between U.S. ZIP codes and ~30 million Canadian change-of-address to track residential mobility, results show that neighborhoods with similar cultural styles and amenities are significantly more connected. These effects persist even after controlling for race, income, education, politics, housing costs, and distance. Urban cohesion and segregation depend not only on who lives where or how far apart neighborhoods are, but on the shared cultural and material ecologies that structure movement across the city.

💡 Research Summary

This paper presents a novel relational model to explain why some neighborhoods are more connected than others, arguing that beyond classic demographic, economic, and geographic factors, the alignment of cultural styles and amenity mixes between neighborhoods creates a “soft infrastructure” that channels urban mobility.

The study leverages two massive, longitudinal datasets to capture different layers of mobility. For the United States, the researchers constructed a co-visitation network using approximately 650 million Google Places reviews, linking ZIP codes when the same user reviewed establishments in both. This network reflects short-term, consumption-oriented movement. For Canada, a residential mobility network was built from about 30 million official change-of-address records in tax filings, linking Forward Sortation Areas (FSAs) to track longer-term relocation patterns.

The analysis begins by validating the networks against known urban structures, using Chicago and Toronto as examples. The networks successfully reveal expected patterns, such as Chicago’s strong downtown-centric ties and North-South divide, and Toronto’s polycentric structure with strong flows within its former boroughs. The researchers then employ network regression models across all metropolitan areas in both countries. The dependent variable is the strength of connection (edge weight) between a pair of neighborhoods. The key independent variables are measures of cultural similarity (based on a human-coded “scene” analysis of local amenities’ symbolic meanings) and amenity mix similarity (based on the functional composition of local points of interest).

Crucially, the models control for a comprehensive set of standard variables: racial composition, median income, education levels, political leanings (voting patterns), housing costs, and geographic distance. The core finding is that neighborhoods with more similar cultural styles and amenity mixes exhibit significantly stronger mobility ties, both in terms of co-visitation in the U.S. and residential moves in Canada. These effects persist robustly even after accounting for all the traditional controls. This suggests that shared cultural ecologies and material affordances act as distinct relational forces guiding how people navigate and relocate within cities.

The study makes significant contributions by formally integrating cultural and amenity-based dimensions into quantitative models of neighborhood connectivity. Methodologically, it demonstrates the power of combining large-scale behavioral trace data with network science to conduct a multi-national, multi-mobility, and multi-temporal analysis. The findings imply that urban cohesion and segregation are not solely functions of who lives where or physical proximity, but are also shaped by the symbolic and functional “fit” between places. This relational perspective opens new avenues for understanding social integration, spatial inequality, and the broader organization of city life, suggesting that policies aimed at fostering urban connectivity might need to consider the cultural and amenity ecologies that constitute the everyday experience of place.
