This data set is adapted from the 2000 Census (5% sample, person records). It is mainly restricted to programmers and engineers in the Silicon Valley area. (Apparently due to errors, there are some from other ZIP codes.)
There are three versions:
prgeng, the original data, with categorical variables,
e.g. Occupation, in their original codes
peDumms, same but with categorical variables
converted to dummies; due to the large number of levels the birth
and PUMA data is not included
peFactors, same but with categorical variables
converted to factors
The variable codes, e.g. occupational codes, are available from the Census Bureau, at http://www.census.gov/prod/cen2000/doc/pums.pdf. (Short code lists are given in the record layout, but longer ones are in the appendix Code Lists.)

citizens; 5 means noncitizen (including permanent residents)
