Country of origin
The country of origin of people born abroad is their country of birth. For people born in the Netherlands, origin is determined by the parents’ country of birth. In cases where both parents were born abroad, origin is determined by the mother’s country of birth. This is because the mother’s birth details are more likely to be known than those of the father. If the mother was born in the Netherlands or the mother’s country of birth is unknown, the father’s country of birth is used.
