I recently downloaded the NSCG 2015 and 2017 files from NSF, and noticed that they are somewhat different than the IPUMS versions of previous NSCG data. Is there some prewritten code (ideally in Stata) for making these data sets comparable quickly? Also, when will the NSCG 2015 and 2017 data be released on IPUMS? Thanks.
Unfortunately, the grant that funded the existing IPUMS Higher Ed project is no longer operational. Therefore, at this time we do not have plans to integrate the 2015 and 2017 NSCG samples into IPUMS Higher Ed. Also, the IPUMS harmonization process is not executed in Stata or any other statistical software and so we do not have any pre-written code that harmonizes these data.
