The Research and Development Survey (RANDS) is a series of cross-sectional
surveys from probability-sampled commercial survey panels which began in 2015.
RANDS 3 was administered by the National Opinion Research Center (NORC) using the
Amerispeak Panel in the spring of 2019 and contains existing questions from
the National Health Interview Survey (NHIS) as well as embedded probe questions
and split-panel experiments for cognitive evaluations.
