Biggest Cities in the World Quiz

Chengdu urban pop is: 7.7 million, Chongqing at least 7 million, Hangzhou-Shaoxing 8.2 million. Shenzhen has recently joined up with the city of Dongguan in the north (check it out on Google Earth) - and arguably Guangzhou though a river divides them. Shenzhen-Dongguan counts 18.3 million. Dhaka is now 15 million (contiguous city not just the city limits). The Ruhr city in Germany of the merged cities of Essen, Dortmund, Duisburg, Bochum and Dusseldorf counts contiguously 8 million.

-But don't tar all the cities with the same inflation, for example Washington DC is contiguously merged with Baltimore thanks to the sprawl. I think the count although not as high as 8 million still makes it 6 million anyhoo.

The US is the only country to base it's counts on commuting habits, if other cities round the world would do the same places like Istanbul, Beijing, Cairo would increase to well over 20 million etc

I got all the hard Chinese cities that I just recently new of so it was hard and I missed out the more obvious ones like Bangalore and Kinshasa

Missed San Francisco

*Facepalm*

Thus it ignores 'city proper' populations (that's the count of people within the official city boundaries). For example the City of San Francisco is only 800,000 but it continues well past these boundaries as one large urban area of 7-8 million.

It also tries to ignore 'agglomerations' or 'CSA' counts which lumps separated cities and towns together -these usually get counted together as one due to proximity or commuting habits. Truth be told some CSA counts have slipped through into here such as NYC's inflated figure (it really should be below 20 million, but gets an extra million or two by doubling its catchment size that takes in smaller communities in large tracts of open farmland and forest). Likewise as people have ponited out Boston is also a misnomer, a 4.7 million urban area that draws in 8 million via its 'commuter' belt.
