Abstract Young adulthood is a critical period in civic development. However, measuring electoral participation among this group generally—and the many young people who go to college in particular—is fraught with potential pitfalls stemming from a reliance on survey-based measures of voting. In this note, we compare patterns of youth turnout in two large-scale, survey-based datasets commonly used to measure voting, the Current Population Survey and the Cooperative Congressional Election Study, to two voter-file based datasets: the National Study of Learning, Voting, and Engagement (NSLVE) and a comprehensive nationwide voterfile provided by the Data Trust. We find high levels of concordance between measures in the NSLVE, Data Trust, and the CPS. However, despite linking their sample to validated voter records, the CCES does not mirror these benchmarks. We conclude by discussing the challenges and opportunities that shape the study of youth turnout.
