I would like to match up questions in the volunteer supplement with income and insurance data. How do I do this?

I want to link records for the volunteer supplement with a Total personal income (an ASEC variable). Are there linking variables I should use?

Yes, this is possible due to the new linking variables CPSIDP and MARBASECIDP. For more details about the process of linking using these variables see this working paper.
