“…Will their data be used for one research project and then destroyed, or will they be archived for secondary use? Sponsors of repeated cross-sectional surveys, such as NHANES, and of longitudinal surveys that follow panels of individuals over time, such as HRS, generally want to retain data for a wide range of secondary uses, many of which are not explicitly foreseen at the time of data collection. …”
