One estimate of customer preference (given by a Pakistani banker) in the Pakistani banking industry, was that about 10% of customers were "strictly conventional banking clients", 20% were strictly Shariah-compliant banking clients, and 70% would prefer Shariah-compliant banking but would use conventional banking if "there was a significant pricing difference". A survey of Islamic and conventional banking customers found (unsurprisingly) Islamic banking customers were more observant (having attended hajj, observing salat, growing a beard, etc.), but also had higher savings account balances than conventional bank customers, were older, better educated, had traveled more overseas, and tended to have a second account at a conventional bank. Another study, using "official data" reported to State Bank of Pakistan, found that for lenders who had taken out both Islamic (Murabaha) financing and conventional loans, the default rate was more than twice as high on the conventional loans. Borrowers were "less likely to default during Ramadan and in big cities if the share of votes to religious-political parties increases, suggesting that religion – either through individual piousness or network effects – may play a role in determining loan default."
