In 1979, EMP, STUDENT, and RETIRED are mutually exclusive - a person can be coded only as one of the three. The original variable (ptoim) asked respondents to choose from one of the following: "employed", "unemployed", "student", "chronic disability/illness", "pensioner otherwise", "homemaker" or "other".
