MAIN

QUESTIO

N

Are physical fitness options equally accessible for different communities in Los Angeles?

•Comparison Areas

• A group of high income communities (Malibu, Pacific Palisades, Brentwood, Agoura Hills)

• A group of low/moderate income communities (Compton, Watts)

Skills demonstrated: Inset map, boundary subset selection (LA Area was derived by selecting cities within three miles of Los Angeles City)

SKILLS DEMONSTRATED: Attribute sub-sets (the following variables were derived from selecting attributes based on road type: interstates, freeways, major arterials), slide with 7+ layers

*With adequate 2000 Census data Skills demonstrated: buffer zones, chart, centroid calculation. Parks above .25 square miles was derived by selecting parks with an

area above .25 square miles from all parks within LA Area

SKILLS DEMONSTRATED: Aggregating Attribute Fields (Crime rate determined by ((2008 Part I CRIME/2008 District Population Estimate)*100,000))

CONCLUSIO

N

Are physical fitness options equally accessible for different communities in Los Angeles?

Based on index results, I conclude that exercise is indeed less accessible for residents of Compton/Watts than for residents of Malibu/Pacific Palisades/Agoura Hills
