North Eastern Region of Jharkhand  

Wiki says North Eastern Region of Jharkhand is Angika region.  However, official language of theses districts of Jharkhand is not Angika but Hindi, Santali.  This is confusing.  So, it needs some clarification as to how come district of Jharkhand where the official language is Hindi, Santali could be Angika region.  Only those districts would be in Angika region where official language is Angika.
