Tract 402 Area Changes Illustrated
This file uses a map and the area of tract 402 to illustrate how each relationship file record corresponds to a unique tract boundary change. Although population is what drives Census tract boundary changes, area lends itself well to visualization, which promotes a more intuitive understanding of the relationships of tracts across Censuses. Changes in area do not always mean population and housing unit counts changed because of the new conventions for unpopulated areas, however, population and/or housing unit count changes necessarily involve a change in area.
The boundary lines are dark green where the 2000 tract boundaries coincide with the 2010 tract boundaries. The 2010 Census tract boundaries are light green in color and the 2000 Census tract boundaries are black in color where they differ from each other, indicating tract changes between the two Censuses. The tract numbers displayed are those of the 2010 Census.
