Anonymization is a bit of a misnomer here. This dataset is clearly pseudonymised. Most datasets at the level of the unit of observation are never truly anonymous, unless they barely contain any real information at all. However this can be sufficient to protect privacy as long as the dataset is never allowed to be combined with other information.
