Population Density

Two different depictions of the population:

• Population per tract, which does not account for the different sizes of the tracts.  Some of the largest population tracts also have the largest areas, so the people are really spread out in a rural tract.  The Census Bureau exaggerates this effect, since they try to make tracts have nearly the same population.
• Population density (people per square kilometer or square mile), which emphasizes the urban areas.

Compute ratio like population density:  Edit button,  Field arithmetic, Quotient 2 Fields (ratio) from a shapefile, and then pick the name for the new field.
