Data The boundary data was derived from the Bureau of the Census TIGER 1992 database. Boundaries are available for states, counties, census tracts, county subdivisions/minor civil divisions, and census blockgroups. One, or a multitude of counties (or entire states) may be defined as the area of interest. Demographic data available for mapping was derived from the Bureau of the Census STF3A 1990. Roughly 225 variables are selectable either for mapping purposes or can be printed in tabular reports. Map layout, colors, legends and titles can be customized by the user. A recoding option is provided enabling the creation of user defined variables.
