The Gaza Strip is frequently referred to as one of the most densely populated areas in the world. It has a density of approximately 13,700 people per square mile, which is about the same as the city of Tel Aviv. If you compare Gaza to a country, then it would rank fifth, but is not even close to the top two – Monaco (68,212) and Macao, China (56,247) – according to UN and World Bank figures.
Gaza City is the 40th most densely populated urban area in the world at 42,600 per square mile. This only about half the density of what the Washington Post said is the densest city – Mumbai, with 83,800 per square mile. According to Wikipedia, Mumbai is fifth behind Manila’s 119,600 per square mile, which is nearly three times more densely populated than Gaza City.
