The Research and Development Survey (RANDS) is a series of cross-sectional surveys using probability-sampled commercial survey panels. The fourth round of RANDS (RANDS 4) was administered by NORC at the University of Chicago using the AmeriSpeak Panel from July 17, 2020 to August 24, 2020. RANDS 4 contained the embedded probe questions and experiments as in previous rounds of RANDS, but had an emphasis on disability and the use of opioid pain relievers. RANDS 4 has a known survey sampling design and can be used to produce nationally and 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.
