I have not gotten my opinion from Barelwis; it is based on my own experiences. The Barelwi inclined are the overwhelming majority outside of the major cities (bear in mind that most Pakistanis do not live in Urban areas) and even within the cities, from my own experiences, they are the most numerous, if not the majority. Regarding the numbers of Madrassahs and Masjids in a given city and the orientation of its ulema or management, how can that accurately reflect the orientation of the laymen in that area? What percentage of people in Pakistan, period, are Madrassah students? What percentage head Masaajid? That number is infintessimal and whatever evidence of the "Deobandiness" of an area that Madrassahs and Masjids attest to is applicable to that infintessimal number.
So how would you go about making the distinction? For myself, if someone engages (or believes in the permissibility of) making Tawaaf to or Sajdah around the graves of the pious, affirms the Barelwi understanding of "Haazir wa Naazr" for the Rasul (peace be upon him), and engages in a multitude of other bidahs like burning incense at graves, subcontinent-style Mawlids, etc. he is a Barelwi even if he never heard the name since these are the hallmarks of the Barelwi "Maslak" or "Minhaaj". Do you have an alternative way of looking at it?
