The EFAA MAPS project in partnership with CU Boulder aims to spatially map EFAA clients to identify gaps in service coverage and compare services to poverty levels. The project visually maps client addresses, converts them to density maps, and compares client household densities to census tract median income data. Mapping is done using the ETO client database, census data, GIS software, and data analysis tools. The maps provide important insights into service coverage and help EFAA better understand and serve client needs.

2. IDEA FORMATION

3. OBJECTIVES
• Spatially map EFAA clients to see geographical
coverage of services and identify any coverage
gaps
• Compare service coverage with levels of poverty/
income in Boulder and Broomfield counties
• Update our service maps to be able to more easily
and visually explain what services EFAA provides
where

4. VISUALIZING THE DATA
FROM IDEAS TO MAP
• Looking for Spatial Patterns
- Address Location
- Turning Households into Points
- Creating Density Maps aka ‘Heat Maps’
• Allows for comparison of households per census tracts
to census demographic data, such as median
household income per census tract.

5. HOW IT WAS DONE: TOOLS
• ETO Client Database
• Census Data
- American Community
Survey 2009-2013
(Demographics)
- TIGER Line Data
(Geospatial topology)
• State and County GIS Data
• Software: Esri’s ArcGIS,
Excel, RStudio and R
scripting language
DATA AND SOFTWARE USED

6. METHODOLOGY
• Obtain and Clean Data
• Address Location - Data to points to map
• Households and Program Usage
• Create Geospatial Statistics: Density Layers based
on proximity
• Count households within census tracts, symbolize
and compare to tract demographic attributes

17. DATA TRANSPARENCY
• Important to note census
tracts have increased
income inequality within
them
• Constraints of both the
Data and Time

18. WHY MAPPING IS IMPORTANT
AND HOW IT BENEFITS YOU
• Geospatial pattern analysis
• Benefit to EFAA
• Benefit to client
• Future mapping capabilities
• Following demographic trends over time
• Mapping donors
