Outside America (from an Orthodox site):
Worldwide Jewish population: 13.3 million.
Worldwide Orthodox population: about 1.8 million. (About one seventh.)
What about Israel, bastion of the Orthodox status-quo?
Israeli Jewish population. about 5 million.
Israeli Orthodox population: 1 million.
One seventh and one fifth. Not a third, not a half. Not even close. But you'd never know it from reading the frum blogs, would you?
