JTYEARS is a Census Bureau recode that gives the number of years the respondent has worked in his/her current job.
This variable is part of the Job Tenure Supplement.
There is a slight comparability issue between 1983 and 1987 and the rest of the available years. In 1983 and 1987, only those respondents who reported less than a year of tenure with their current employer were asked to specify a number of months worked for said employer. As a result, for these samples, fractional years are only available for those who report less than a year with their current employer. In years after 1987, number of months are asked of respondents who reported less than 3 years with their current employer.
This variable is completely comparable for all years between 1996 and 2012. Before 2012, all values were possible. In 2012 a topcode at 39 was introduced - all years 39 and above are coded 39. In 2014 and 2016, documentation states a topcode of 39, but the data show a possible true topcode of 32.
After 1996, the universe includes employed individuals aged 15 and older; prior to 1996, employed individuals aged 14 and older are included.
- Jan 1987 and Jan 1983: Civilians age 14 or older and employed during the reference week, and were doing the same kind of work they were currently doing during the previous year, and were working for the same employer they were working for a year ago.
- 1996+: Civilians age 15 or older and employed in the reference week.
