A data set for 1980 Presidential election results covering 3,107 US counties using geographical coordinates. In addition, three spatial neighbour objects,
k4 not using Great Circle distances,
dll using Great Circle distances, and
e80_queen of Queen contiguities for equivalent County polygons taken from file
co1980p020.tar.gz on the USGS National Atlas site, and a spatial weights object imported from
elect.ford - a 4-nearest neighbour non-GC row-standardised object, but with coercion to symmetry.
A SpatialPointsDataFrame with 3107 observations on the following 7 variables.
FIPS a factor of county FIPS codes
long a numeric vector of longitude values
lat a numeric vector of latitude values
pc_turnout Votes cast as proportion of population over age 19 eligible to vote
pc_college Population with college degrees as proportion of population over age 19 eligible to vote
