Dhaka, the capital of Bangladesh grew strongly between 2001 and 2011 and is by far the most densely populated urban area in the world. Dhaka's density is estimated at 115,000 per square mile or 44,000 per square kilometer, with slum (informal dwelling) densities reported report up 4,210 per acre, or 2.7 million per square mile (1 million per square kilometer). At this density, all of the world's 3.7 billion urban residents could be accommodated in an area approximately equal to that of the Washington (DC-MD-VA) urban area. The density of the US is 84 people per square mile. Canada has just over 9 people per square mile! We just don't realise how good we have it here!
