Cities with most Ultra Orthodox Jews (Hareidim)

Enter the cities that have the most Ultra Orthodox strictly religious Jewish population. [Please note that it's very difficult to define what is considered ultra Orthodox, so I basically used the following criterias: - Jews who keep a strict Jewish lifestyle, following the commandments of the Torah. - Are separated from the rest of the world the way they dress, and live in their own separated community. - The children attend private religious schools. Also note that there's no clear data of all the cities in the world, and while Israel have detailed numbers of how many ultra Orthodox are living in each city, the rest of the world doesn't have much data, so I made my own research from the Hebrew Wikipedia and some other Jewish websites, and created the best that I can]. Enjoy the quiz!
