With the release of the statistics for 2022, ZOO2 has been discontinued and replaced with ZOO3 that instead of showing activities by region shows activities by category of zoo: Zoos and Aquariums.

ZOO3 also includes more types of activities than ZOO2: Informative or educational events and participants, Invitational events and participants, volunteers and volunteer hours worked, as well as total admission revenue incl. annual passes (DKK). ZOO2 can be found under "Archive" and is comparable on a general level.
