usethnicity: Data from Youth Risk Behaviour Survey

Description

This data set contains variables on race and ethnic identification from the 2017 Youth Risk Behaviour Survey, together with two variables on smoking behaviour. The YRBS is a multistage cluster-sampled survey, so valid inference about associations requires using survey design information. This subset is useful only for demonstration purposes.
