Did I say Muzaffarpur district has more population? NO
I just meant the difference in district population is not huge.
And it's not just about Muzaffarpur. North Bihar as a whole is very densely populated having 65% of Bihar's population. Do you have cities in such proximity in south of the Ganges as it's in the north?
No offense to Patnaites but...
more... it's a fact that whether it's Darbhanga or Muzaffarpur or any other city, it doesn't gets it's fair share of trains and connectivity, also considering the fact that it's mostly people of Mithila Plains & Saran who are migrants.
