\description{
Data on median housing values from 506 census tracts in the suburbs of Boston
from the 1970 census. This data frame is a corrected version of the original
data by Harrison and Rubinfeld (1978) with additional spatial information.
The data were taken directly from \code{\link[mlbench]{BostonHousing2}} and
unneeded columns (i.e., name of town, census tract, and the uncorrected
median home value) were removed.
