The Research and Development Survey (RANDS) is a series of cross-sectional surveys from probability-sampled commercial survey panels. As part of a special iteration of RANDS that focuses on COVID-19, RANDS during COVID-19 Round 3 is the third round of a three-round survey. The sampled participants of RANDS during COVID-19 Round 3 were recruited using NORC at the University of Chicago (NORC)’s AmeriSpeak Panel, and the survey was administered by NORC from May 17, 2021 to June 30, 2021. RANDS during COVID-19 Round 3 has a known survey sampling design and can be used to produce nationally and sub-nationally representative estimates.

Summary of differences

The restricted-use file may include lower-level geography and select variables not available on the public-use file due to possible disclosure risk. Most restricted-use geographic NCHS variables can only be used to merge external data or to categorize geographic areas with similar characteristics. Researchers should not estimate regions smaller than the specific survey's sample design would support, even when smaller levels of geography are available.
