Gordon, they may not be urbanized to the extent that Iran and Algeria and Tunisia are, but they nevertheless have considerable migration into cities from rural areas, growth in GDP and per capita income, falling rates of infant mortality, and so on.

Stanley Kurz has done some original research on how cousin-marriage from the old country has produced MORE cultural stasis in Pakistani immigrants, not less. Essentially rural Pakistan is colonizing England. Not English making Pakistani immigrants into “colorful Englishmen.” The incidence of female genital mutilation, honor killing, burqua, forced/arranged teen marriages, etc. shows this process.
