This data supports the examples in the SeerMapper package and contains demographics for Georgia (GA) and Washington (WA) state. Each dataset contsins the location IDs (either a county FIPS codes (5 digits) or census tract FIPS code (11 digits)), the abbreviation of the associated Seer Registry (if any), 2000/2010 population, area in sq. miles of each county or tract, 2000/2010 population density (pop/area), population 65 years old or older, the number of housing units, the number of units occupied, the number of units occupied by owner, and population of hispanics.
In Georgia all counties and census tracts belong to registries. The three Seer registry areas in Georgia are identifed, using the abbreviations of: GA-ATL, GA-RUR, and GA-OTH. In the examples, this data is used for full state mapping, Seer registry areas mapping (subdivided by Seer registry area abbreviations), and randomly selected data to represent different situations for partial data collections. This data can be used by both the SeerMapper package,
