All data are in the file wh8492d.txt, which is an ASCII file in DOS 
format. It is zipped in the file skc-data.zip. Unix/Linux users should 
use "unzip -a".

The file wh8492d.txt contains the following variables:

  hr83-hr92: annual working hours for wife for 1983-1992
  race: wife's ethnicity (Black=2, White=1)
  age84-age92: wife's age for 1984-1992
  hinc83-hinc92: husband's annual income for 1983-1992
