Description

Phase 2 data: Herfindahl-Hirschman Index: A measure of how mixed the land uses in a neighbourhood are. There were 5 possible land uses contained in a neighbourhood; including residential; commercial; institutional/governmental; recreational and mixed landuses. (Range: 0 to 10000; 10000=least mixed; 0=most mixed) HHI = Sk(pk*100)^2 p is the proportion of land area devoted to the specific land use (k) in each buffer. As for the LUM entropy score; the proportions (pk) were calculated as the land area devoted to a specific land use divided by the total area of walkable land uses in each buffer. Note: LUM=10;000 (i.e. no mix) if none or only one of the relevant land uses fell into the buffer.
