I requested to download the 2017, 2015, 2013, and 2011 CPS samples. Upon downloading and running a frequency of the variable ‘year’, I noticed that ‘2016’ is included in the sample. I double-check my original data submission and I had not requested 2016. Any thought(s) as to why this is the case? Thanks!
It turns out that by deafult a coupld of monthly samples were also elected.
In a recent update to IPUMS CPS a number of the most recent basic monthly samples from 2016 and 2017 were made “default” samples. So, without deselecting these samples, they will be added into your extract. I will let the IPUMS CPS team know that you found this confusing as we are always trying to improve ease of use and overall user experience.
