Longitudinal cohort in TUS 2014/2015?

I've been working on a repeated cross-sectional analysis using CPS-TUS data spanning 2001-2015, and I would like to exclude longitudinal cohort observations in order to preserve the cross-sectional analysis. It seems that there are individuals with the same CPSIDP values in the July 2014 and May 2015 samples, but I wouldn't expect a longitudinal cohort based on this explanation: https://cps.ipums.org/cps/tobacco_sam...


Could you clarify whether there are longitudinal cohort observations linking July 2014 and May 2015 data in the TUS?

I've replicated your observation that the 2014-2015 wave seems to be a longitudinal cohort. I am also unable to find any documentation from the Bureau of Labor Statistics, the Center for Disease Control, or the National Cancer Institute noting that the 2014-2015 wave includes a longitudinal component. We will be reaching out to our contacts for more clarification. In the meantime, treat the 2014-2015 wave as including a longitudinal cohort. If your aim is to pool these samples for cross-sectional analysis, then I'd suggest excluding the second TUS supplement response. We will be sure to update our documentation accordingly once we have further clarification.
