Country of origin
The origin of people born abroad is determined by their own country of birth. For people born in the Netherlands, origin is determined by their parents’ country of birth. In cases where both parents were born abroad, origin is determined on the basis of 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 to determine their origin.
