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

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, gender identity, 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.
