I’m Lisle Hites, Chair of the Needs Assessment TIG and Director of the Evaluation and Assessment Unit (EAU) at the University of Alabama at Birmingham (UAB). Today’s posting is about the use of data visualization to enhance your needs assessment.
Recently, my team worked with a state agency to help them identify potential sites for a pre-k development initiative. We used ArcGIS 10.2 Geographic Information Systems (GIS) technology to geocode and map all child care centers and grant applicants within the state. In turn, these data were displayed on an interactive, web-based map using ESRI’s ArcOnline platform. Supplemental data regarding percentage of people in poverty were added to the map to enhance the decision making process for policy makers (American Community Survey Census).
Displaying these multiple sets of data visually allowed state representatives to see the highest concentrations of four year olds in the state as well as potential gaps in service coverage by existing pre-k programs. In other words, these data were used to reduce the potential for duplication of services and to identify areas of greatest need.
- Needs assessments can be conducted in a variety of ways using existing data in new and innovative ways.
- While state representatives had ideas of what they wanted to know, data visualization led them to refine their questions and identify additional sources of information to support their “data-driven” decision.
- Hardcopy paper maps of each county did not provide enough geographic detail of childcare facilities. To maximize the large amount of disparate data, an online interactive mapping platform was critical to the success of this project.
