Build Your Own

Start building a Promise Zone by selecting any one county on the map. From there, you will be able to select geographically contiguous counties. Click the Neediest Neighbor button to select the neighboring county with the highest rate of poverty.

The dark blue counties on the map are areas where poverty rates are high.

The red counties are those that you have selected to be part of your Promise Zone. The summarized and detailed statistics for all of the Promise Zone counties are shown on the left. The enabled counties surrounding the Promise Zone are those that are eligible to be added.

Data Sources

• Promise Zone data set which is a transformed dataset from the source from Housing and Urban Development Department
• Local Area Unemployment Rates from the U.S. Bureau of Labor Statistics
• Occupational and Census Data from the Census 2013 American Community Survey (via Socrata)
• Geographical data CartoDB

We wrangled all this data into one GeoJSON file and converted that into TopoJSON, which is what this page reads in.
