About the Project Data:

The demographic statistics running along each street are taken from the
2000 US Census. The selected categories were chosen as they
illuminate important characteristics of urban space – both regarding the
physical infrastructure as well as the demography of Wilmington residents.

This small selection of data can provide an illuminating layer of information
about the represented neighborhoods of Wilmington. This data, however, is
not an exact or complete representation of these communities. It does indicate
patterns and trends in the physical fabric and demographic nature of Wilmington.
