The category “unknown” is used in a variety of situations, as discussed in Section 3.3.2.1 below. In some cases, a person may be registered as having “unknown” nationality pending action by their foreign parents or guardians to undertake procedures so that the child acquires their nationality. In other cases, it is used when the determination of nationality is problematic. The second highest number of persons registered as having “unknown” nationality also have their country of birth indicated as “unknown”.
