The compact city model has received increased attentions as a desirable urban form for sustainable development. While multiple features characterize a compact city, density and proximity are the essential features. However, many studies assume that high-density cities have better proximity without testing this relationship. Against this backdrop, our study aims to identify the relationship between the two for thirty global cities in developed and developing countries. For the global comparative study, we utilized various open-source big data, including NTL (Night Time Light), data from Open Street Map (OSM), and WorldPop population data. For the analysis, we first identified the boundary of individual metropolitan areas and their cores, using NTL and POI (Point of Interest) data from OSM, estimated net density, and measured proximity, a network distance to the closest core. The significant findings from the study are the following. First, the size of the identified metropolitan areas is twice that of administrative areas. Second, a different result in the direction of the relationship between density and proximity is observed between developing and developed countries. While denser cities in developed countries appear to have better proximity, the opposite trend is observed for cities in developing countries.
