The dataset contains data of a nationwide anonymous online survey among whole blood donors in Germany in 2020, which was performed to quantify and to investigate non-compliance of donors with deferral criteria for non-sexual risk exposures. It covers anonymous sociodemografic information and non-disclosure of non-sexual risk exposures prior to last donation (e.g. travel to malaria endemic regions, mild or febrile infections, body modifications). The file contains study data (sheet "data"), description of variable content and coding (sheet "variables") as well as data for the underlying invited and total donor population (sheet "post-strat") .
