Are respondents in the IPUMS higher ed surveys also in the IPUMS USA surveys? If so, how do you link them?

I am looking to link data sets. IPUMS Higher Ed data comes with an individual identification number: personid . I do not see this same variable in the IPUMS USA data sets. Is there a way to link these two datasets or are these surveys not the same respondents?

The data in IPUMS USA and IPUMS Higher Ed are completely independent from each other. IPUMS USA data comes from the US Census and IPUMS Higher Ed data comes from surveys conducted by the National Science Foundation. Therefore individuals included in each sample are not able to be linked between the two projects.
