+The target variable is the median house value for California districts,
+expressed in hundreds of thousands of dollars ($100,000).
This dataset was derived from the 1990 U.S. census, using one row per census
block group. A block group is the smallest geographical unit for which the U.S.
Census Bureau publishes sample data (a block group typically has a population
of 600 to 3,000 people).
+An household is a group of people residing within a home. Since the average
+number of rooms and bedrooms in this dataset are provided per household, these
+columns may take surpinsingly large values for block groups with few households
+and many empty houses, such as vacation resorts.
