NCHS Research and Development Survey (RANDS) Round 8 Restricted File

Add to My Basket

Description

The Research and Development Survey (RANDS) is a series of cross-sectional surveys using probability-sampled commercial survey panels. Some rounds also include non-probability panels. The eighth round of RANDS (RANDS 8) was administered by NORC at the University of Chicago using the AmeriSpeak Panel. Samples also were purchased by NORC from the Lucid and Community Marketing Insights (CMI) non-probability panels. Data were collected from June 8, 2023 to July 24, 2023. RANDS 8 contained the embedded probe questions and experiments as in previous rounds of RANDS. It included questions on disability, aspects of life, emotional well-being, and the reason behind perceived acts of discrimination. The AmeriSpeak part of RANDS 8 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.

Does Geography Differ from Public Version?
No
Does Level of Variable Detail Differ from Public Version?
No
