Good point.

Bnei Brak is a city in the greater Tel Aviv metropolitan area that is home to mostly Ultra Orthodox Jews. Being that it's mostly a low income community there isn't too much vertical building (skyscrapers are more common to high income and business areas like Tel Aviv and Ramat Gan), but due to their typically high birth rate (in average over 6 kids per household) the population density there is still incredibly high as large families share small, cramped apartments.
