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 BostonHousing2 and
unneeded columns (i.e., name of town, census tract, and the uncorrected
median home value) were removed.
