It all depends on definitions. Some consider “Hareidi” (i.e. “Ultra-Orthodox”, ro “fanatic”) to mean wearing a yarmulke in public, with married women covering their hair, etc. — and “normal” Orthodox (especiallyas defined 60 years ago, e.g. people such as former Senator Lieberman or Treasury Secretary Lew) to include anyone who belongs to an Orthodox synagogue — then the numbers might be correct.
If you count as hareidi only someone who is so much into yiras shemayim that they never think of doing an aveirah (never speak lashon hora, certainly never look at news sites such as this which are full of lashon horah) then the numbers are quite different.
