According to my tabulation, the number of observations employed (empstat=01,10 or 12) is smaller than the sum of observations working fulltime or parttime (fullpart=1 or 2). This is so weird because the number of individuals working fulltime and parttime should add up to the number of working people.
Why is the number of observations for employed (empstat=01,10 or 12) smaller than the sum of fulltime and parttime
The discrepancy here is due to a difference in the reference period of each variable. FULLPART records the full-time/part-time status of respondents who were employed during the previous calendar year. In contrast, EMPSTAT refers to respondents’ employment status over the past week. As a result, FULLPART will capture a larger number of employed persons.
Hope this helps.
