The Understanding America Study HRS Wave 2 surveys were the second series of HRS surveys that UAS respondents are invited to. They functioned as the first follow up to the UAS HRS Baseline. This happened two years after completion of the UAS HRS Baseline, that is, two years after completion of UAS 25.

As of June 7th, 2019 the UAS HRS Wave 2 has been replaced by the UAS HRS Wave 3. Respondents currently participating in the UAS HRS Wave 2 continue to do so until the entire wave has been completed.
