Is the variable PUSLFPRX (INFORMATION COLLECTED BY SELF OR PROXY RESPONSE) excluded from IPUMS-CPS?

I feel a bit silly perhaps because it is my first time at this site

but I did not manage to find this or a similar variable.

Any help will be appreciated

Currently, we only have an equivalent to PUSLFPRX in a few supplement samples. If you need this variable for other CPS samples, I recommend linking your IPUMS-CPS extract to the original CPS data. The IPUMS household linking variables can be found here. To link person records, you will also need to use LINENO, AGE, and SEX. The corresponding NBER variables are identified in this documentation.

Hope this helps.
