Pre-1976 monthly CPS data

I was wondering if it’s possible to get monthly cps data pre-1976. I see the ASEC goes back to 1962, but when I download that data the month variable only takes a value of “March”, so I am unable to create monthly data from it.

Thanks for your help,

IPUMS does not have any pre-1976 basic monthly CPS files. To the best of our knowledge, a complete series of basic monthly microdata files pre-1976 does not exist. A few of the (non-March) pre-1976 supplement microdata files do exist (and these include the basic monthly data). Some of these supplements are available through ICPSR.
