As part of a special iteration of RANDS that focuses on COVID-19, RANDS during COVID-19 Round 1 is the first round of a three-round survey. The probability sample of RANDS during COVID-19 Round 1 was recruited using NORC at the University of Chicago (NORC)'s AmeriSpeak Panel, and the survey was administered by NORC from June 9, 2020 to July 6, 2020. The RANDS during COVID-19 Round 1 Probability Sample has a known survey sampling design and can be used to produce nationally and sub-nationally representative estimates.
