As we know, there was an important redesign of the CPS starting in 1994 and some labor force statistics are not comparable in time due to this change. Polivka and Miller, 1998 (*The CPS After the Redesign: Refocusing the Economic Lens*) estimate adjustment factors to revise some pre 1994 estimates of labor market measures (the most used, unemployment rate, …). I am interested in adjust a measure for which they did not provide an adjustment factor and for which I find an abrupt change since 1994, which is clearly due to the survey redesign. I would like to be able to use the pre 1994 data, but I need to make some sort of adjustment to my estimate. In their estimation of adjustment factors the authors use the CPS and **a parallel survey** they run around 1994, I would like to ask if we can have access to the data of this parallel survey (so I can calculate my own adjustment factor using their methodology)

IPUMS does not have these data. I suggest you reach out to the authors of that paper, or the BLS, directly. There are other publications on the redesign comparison in the references of that paper, as well.
