Interesting because I also know many Pakistanis, Yemenis, Afghans and Bangladeshis and I have yet to meet or hear anyone practicing polygamy or having a second family back home. In fact, my Pashto speaking husband whose extended family comes from a remote area near a Pakistan-Afghanistan border also doesn’t know a single person in his town and nearby villages who practice polygamy. In fact, it is unheard of even though the area is very conservative. This goes for his extended network of friends and acquaintances here in the US too.
I’ll leave this article form Pew Research here as well:
”Fewer than 1% of Muslim men live with more than one spouse in Afghanistan, Pakistan, Bangladesh, Iran and Egypt – all countries where the practice is legal …”
