The attempt was designed to generalize to your U
S. human population in order to allow separate analyses from solutions out of reduced-earnings house. Mathematical efficiency had been adjusted in the degree to pay getting test designs and you will habits out-of nonresponse that might bias efficiency. The original phase involved using a bottom lbs so you’re able to account fully for more options odds and response cost across the try strata. In the second stage, take to demographics was in fact poststratified to fit population parameters. The data is actually weighted into U.S. adult population by sex, decades, studies, geographic part, family members proportions, race/ethnicity, population thickness, civic engagement, and you can volume out-of sites use, making use of the 2019 and 2021 You.S.
