1
Areal land use mix is an entropy measure capturing the evenness of allocation among five categories (residential, commercial, institutional, open, and other), calculated by -[Σk (Pk ln Pk)] / ln N, where N is the number of land use categories and Pk is the proportion of land in each category k.
2
The final face-based measure is the standardized mean of the count of land uses on each face within the neighborhood cluster.
3
Sample proportions weighted to reflect population composition of Chicago as reported in Census 2000.
