Abstract Identifying and understanding areas of interest are
essential for
urban planning. These areas are normally defined from static features of the
resident population and urban amenities. Research has emphasised the
importance of human mobility activity to capture the changing nature of
these areas throughout the day, and the use of digital applications to
reflect the increasing integration between material and online activities.
Drawing on mobile phone data, this paper develops a novel approach to
identify areas of interest based on the degree of complementarity of digital
activities, available amenities and population levels. As a case study, we
focus on the largest urban agglomeration of Chile, Santiago, where we
identify three distinctive groups of areas: those concentrating (1) high
availability of amenities; (2) high diversity of amenities and digital
activities; and (3) areas lacking amenities, yet, presenting high usage of
digital leisure and mobility applications. These findings identify areas
where digital activities and local amenities play a complementary role in
association with local population levels, and provide data-driven insights
into the structure of material and digital activities in urban spaces that
may characterise large Latin American cities.
