Property 37 32008 2023-05-17 NA

Summarises the walkability and urban composition in the area surrounding the property address. Average walkability is measured through a circular buffer at a range of radii. Street centrality measures betweenness and closeness centrality of the residential street and the street network at a range of radii. Land use is measured through Shannon’s Diversity Index through a circular buffer at a range of radii.
Usage instructions: To link to BiB participants, use the id column to link to the property_id variable in bib_geog_person.
