Note: This is not a summary variable concerning labor force status,
employment, etc. It is the introductory question to the labor force
series. For measures of the sib-respondent's labor force status,
employment status, etc., we suggest variables XLFSTAT-XLFCIVS.

In 1975, the question referred to "most of last week". In
1977, the question referred to "presently."

occupation for the 1975 and 1977 surveys.
