It appears that the IPUMS version of May 2015 wave of TUS-CPS does not have a smoking intensity variable for current smokers. (Labeled tcigday in other TUS-CPS files, including Januray 2015.) Based on CPS documentation, it seems the question was asked. Is there a reason why it’s not in the IPUMS file? Does it have a different variable name in May 2015? Could it be included?
