The Gaza Strip is frequently referred to as one of the most densely populated areas in the world. According to the CIA, it has a population of 2,098,389 in an area of 139 square miles (slightly more than twice the size of Washington, D.C.), which would be a density of 15,096 people per square mile, which is less than the density of the city of Tel Aviv (21,793/sq. mi.). If you compare Gaza to a country, then it would rank fifth but is not even close to the top two ­­– Macau (56,247) and Monaco (51,167).
