The goal of yowie is to provide longitudinal wages data sets along with several demographic variables of Americans from the National Longitudinal Survey of Youth (NLSY79) from Round 1 (the survey year 1979) to Round 28 (the survey year 2018). The NLSY79 is a longitudinal project held by the U.S. Bureau of Labor Statistics that follows the lives of a sample of American youth born between 1957-64. The cohort originally included 12,686 respondents ages 14-22 when first interviewed in 1979. There are three data sets provided in this package:
