Misschien zo voor de stricte telling bij het CBS maar daar werk ik niet. In deze context zijn de termen volgens mij prima uitwisselbaar.
Allochtoon (plural: allochtonen) is a
Dutch word (from
Greek ἀλλόχθων, from ἄλλος [
allos] other and χθών [
chthōn] soil/earth/land), literally meaning "emerging from another soil". It is the opposite of the word
autochtoon (in English "autochthonous" or "autochthon"; from Greek αὐτόχθων, from αὐτός [
autos] self/same and again χθών [chthōn] soil/earth/land), literally meaning "emerging from this soil".
In the
Netherlands (and
Flanders), the term
allochtoon is widely used to refer to immigrants and their descendants. Officially the term
allochtoon is much more specific and referred to anyone who had at least one parent born outside the Netherlands.
[1] The
antonym autochtoon is less widely used, but it roughly corresponded to
ethnic Dutch. Among a number of immigrant groups living in the Netherlands, a "
Dutch" person (though they are themselves Dutch citizens) usually refers to the ethnic Dutch.
