SUPPLEMENTAL METADATA (where available)

Census Tracts: The U.S. Census Tracts data set represents a collection of ESRI 
shapefiles that depicts the census tracts for an area. These data sets are the 
actual census tracts and BNAs as defined by the Bureau of the Census. Census 
tracts are geographic entities within a county having relatively homogeneous 
demographic characteristics and a population of 2,500 to 8,000 people. Block 
numbering areas follow the same basic criteria as tracts in counties without
formally defined tracts, but because they occur in lightly populated areas they
may have fewer people.
