Data Set Information:
The data was collected as part of the 1990 census.
There are 68 categorical attributes. This data set was derived from the USCensus1990raw
data set. The attributes are listed in the file (repeated below) and
the coding for the values is described below. Many of the less useful attributes in the original
data set have been dropped, the few continuous variables have been discretized and the few
discrete variables that have a large number of possible values have been collapsed to have
fewer possible values.
More specifically the USCensus1990 data set was obtained from the USCensus1990raw data
set by the following sequence of operations;
- Randomization: The order of the cases in the original USCensus1990raw data set were
randomly permuted.
- Selection of attributes: The 68 attributes included in the data set are given below. In the
USCensus1990 data set we have added a single letter prefix to the original name. We add the
letter 'i' to indicate that the original attribute values are used and 'd' to indicate that original
