Issues with January 2016 CPS Job Tenure Supplement

I’m attempting to measure job attrition from 2015 to 2016 using the variables JTOCC (occupation in 2015) and JTSAME (have you changed jobs since last year?). I get identical results for all JTOCC categories except “0000” (NA) when I switch JTSAME from “01” (not doing same job as in 2015) to “02” (doing same job). I’m unsure what to make of this.

I am not entirely certain of what you are explaining here. In any case, I can note the following. For the January 2016 sample, all observations with JTSAME==2 have JTOCC==0. Observations with JTSAME==1, JTOCC takes on all of the available occupation categories.

Thank you.
