Intersection of Data
Alternative
Analysis:		 Viewing the map animation provided some overview of the variables under study, but left an incompleted picture.

One overall goal of all this research is to identify areas where community development strategies may work.  One theory of community development looks at the needs of a community and another theory looks at a community's assets.

An alternative theory looks for areas that have high needs and high assets and then targets those areas for change.  GIS makes such analysis possible.
The Good: The image below represents only those block groups that were included in each asset map from the social animation variables (churches and United Way programs).
 
The Bad: The image below represents only those block groups that were included in each need map from the social animation variables (poverty, delinquency, neglect).
 
The Intersection: The image below represents the unique polygons that are present in both the "Good" and "Bad" maps above.  This map therefore represents the intersection of the two maps and are those areas that could be targeted for community development under an assets-needs theory of community development.
 
Area Characterisitcs: Below are some characteristics of these "Intersected" block groups (1990 U.S. Census).
  • 73% minority
  • 67% African American
  • 6% Hispanic
  • Median age = 26
  • 51% Female headed households
  • Average household income = 21,202
  • 49% poor
  • 24% very poor
  • Median year of house = 1939
  • Average house value = 40,109
  • Neglect density = 2
  • Delinquency density = 9 (one block group =37)
  • Total churches = 28
  • Total schools = 8
