Anyone know offhand what percentage of American Jews are Orthodox?
Only about 10% of America's Jews are Orthodox.
Half of American Jews are completely secular, and about half of American Jews claim not to believe in God.
Of religiously affiliated Jews, about 40% belong to the very leftist Reform movement.
See, for example, the interesting article at
