GIS Final 2012

Policy Question
• What areas in LA County should United Way target for engagement and resource development and why?
• What factors lead to homelessness and/or have high estimates of homeless populations?
• Create an index to identify areas with high risk
• Identify current resources in the area
• Identify radius to surrounding resources to determine need
Creation of an Index
• Variables used to create an index:
• Homelessness Estimates from Census data
• Predictors of homelessness:
• Percent of population in poverty
• Percent of population unemployed
• Percent of population that is rent burdened
Area #1: Palmdale/Lancaster
• Basic Data:
• Index: Lancaster and Palmdale both have areas that score high on the Index
Irwindale mismatch

Irwindale didn’t have any PSH locations but they had an estimated 50 homeless individuals in the Census Tract

Required Skills Used
• Modeling: I used modeling to create rasters and then reclassify the rasters to create an index
• Measurement/Analysis: I created buffers around the PSH locations to include an 3 mile radius from the point then used this distance to pro-rate the mismatch of units to estimated homeless counts
• Original Data: I received an excel spreadsheet containing information for the PSH Locations including addresses and total unit numbers
