So here is something insightful ...

You should discuss the issue with the agency for which you wish to receive benefit. They will explain the qualifications. I am aware of some qualifications for indigenous peoples, but it may be that is only in my jurisdiction (federal or state court, state legislature, etc.).

So the full answer to your question is: you are going to have to ask those of which you are expecting designation. Not all designation applies in all situations.
