The old Batavian lands are still very homogeneous, with a large Batavian population. However, some scientists claim that the Batavian people can be divided in even smaller ethnic groups, something that's probably right. But if we wouldn't count them as one, we would have tens of groups, mostly groups with an own culture but who feel Batavian.

Batavia has eight different large ethnic groups, which makes the kingdom unique in the Dutch sector.
