I can’t seem to find monthly data through the most recent CPS release (March 2015) in the IPUMS-CPS data – it looks like the last monthly observation in IPUMS is December 2013? Is there a lag on when this gets updated, or does a new year of monthly data get released all at once? Thank you in advance for your help!
The IPUMS-CPS team is currently working on integrating the CPS basic monthly datasets from 1976 to present. There is no official release date for these files at this time, but I would not expect the 2014 samples to be released before the end of this summer. However, all of the basic monthly files and command files for 2014-2015 are currently available from NBER. The variable names in these files will obviously differ from the IPUMS-CPS variable names, but they will contain the same data as will be used to eventually create our integrated variables.
Hope this helps.
