The Walkability Index is a quantitative tool used to measure the pedestrian environment within a geographic area. The Walkability Index is based on a model developed for King County, Washington and Baltimore, Maryland (see reference paper at http://sallis.ucsd.edu/Documents/Pubs_documents/NQLS_Frank%20et%20al%20published%20walkability%20paper.pdf). It includes four components: land use mix, residential density, retail density, and intersection density. Higher scores represent more walkable areas. This data shows the Walkability Index score for each census tract in Los Angeles. Tracts in the Central City, Westlake, Hollywood, and Venice Community Plan Areas have the highest relative Index scores.Use field "Walkabil_1" to project scores and correct features for legend. To learn more about this Index, please review the complete Health Atlas for the City of Los Angeles (pp. 85-86 and 91) or Chapter 7: Land Use of the Health Atlas, both available for download at http://healthyplan.la/the-health-atlas/.Produced by Raimi + Associates for the City of Los Angeles and Los Angeles County. Made possible with funding from the Centers for Disease Control and Prevention through the Los Angeles County Department of Public Health and The California Endowment, May 2013.
