NCHS Research and Development Survey (RANDS) Round 6 Restricted File
Add to My BasketDescription
The Research and Development Survey (RANDS) is a series of cross-sectional surveys using probability-sampled commercial survey panels. The sixth round of RANDS (RANDS 6) was administered by NORC at the University of Chicago using the AmeriSpeak Panel from August 10, 2022 to August 29, 2022. RANDS 6 contained the embedded probe questions and experiments as in previous rounds of RANDS. It also explored different administrations of questions asked on the National Survey of Family Growth (NSFG) through split-sample experiments. RANDS 6 has a known survey sampling design and can be used to produce nationally and sub-nationally representative estimates.
Data Access
NCHS management, access and other fees apply. https://www.cdc.gov/rdc/application-process/fees-and-invoicing.html
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.
