Constructing the measures of neighborhood and amenity complexity. (A) Distribution of point of interests (POIs) across neighborhoods and amenity categories. (B) Map of urban neighborhoods colored by the number of observed POIs. (C) Revealed comparative advantage (RCA) values transformed to a binary specialization matrix (M). (D) Similarity matrix of neighborhoods based on their specialization in amenity categories. This matrix is used to measure neighborhood complexity. (E) Similarity matrix of amenities based on their specialization in neighborhoods. This matrix is used to measure amenity complexity. (F) Relationship between amenity diversity and average amenity ubiquity in neighborhoods. Dots (neighborhoods) are colored by their neighborhood complexity value. (G) Relationship between ubiquity and average diversity of amenities. Dots (amenity categories) are colored by their amenity complexity value. (H) Neighborhoods with higher complexity value are specialized in amenity categories that have a higher amenity complexity value. Each cell in the matrix represents a neighborhood specialized in an amenity category and cells are colored by amenity complexity
