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).
|
||
|
|
|
||
|
|
A 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 surprisingly large values for block groups with few households
|
||
|
|
and many empty houses, such as vacation resorts.
