I want to check something with you all: The universe for the JTYEARS variable in the Job Tenure supplement changes from 1983/87 to 1996 and beyond. Participants had to be employed in the reference week, doing the same kind of work now as they were doing a year ago, and working for the same employer as they were a year ago. For 1996 and beyond, the universe was persons employed in the reference week.
This difference in universes is not mentioned in the comparability section.
However I think that this universe restriction for the early years would inflate tenure values relative to the later years because you’re excluding those who did not work in the same area and with the same employer in the previous year. Thoughts?
