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 2 is the second round of a three-round survey. In addition to the probability sample of RANDS during COVID-19 Round 2, the questionnaire was administered to the Dynata non-probability online opt-in sample by NORC at the University of Chicago (NORC) from August 3, 2020 to August 20, 2020. The RANDS during COVID-19 Round 2 Non-Probability Sample does not have a known survey sampling design and cannot be used to produce nationally or sub-nationally representative estimates.

Is a Public-Use Version (PUF) Available?

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.
