What is the worlds largest city by population?

Answer 1

I'm sure somewheres in China.

Answer 2

This is actually a difficult question to answer... I'll give you the three different way of measuring a city's population, and list the top 5 cities by each definition: (all information from wikipedia)

1)
This is a list of contiguous urban areas of the world ordered according to population (as of 2005). Some of these areas contain multiple metropolitan areas where the built-up areas have merged together.
1 Tokyo, Japan 31,112,000
2 New York/Philadelphia/Hartford,USA 27,860,000
3 Seoul, South Korea 22,447,000
4 Mexico City/Toluca, Mexico 20,861,000
5 Jakarta, Indonesia 20,087,000

2)
This is a list of the most populous cities of the world defined according to the concept of city proper. The list ranks the world's urban municipal units (or well-defined statistical groupings of such units) according to population. Note that the populations listed are for the city proper and not for the urban area nor the metropolitan area.
1 Mumbai, India 13,073,926
2 Karachi, Pakistan 11,608,000
3 Delhi, India 11,505,196
4 São Paulo, Brazil 11,016,703
5 Moscow, Russia 10,654,000

3)
This is a list of the 5 largest Metropolitan Areas of the world, ranked by population. This is a controversial issue rather difficult to quantify, as unlike national subdivisions, there are no consistently defined borders for such an area. Many of the figures for individual cities are highly controversial, and in some cases numbers which differ by millions are given by different sources. In some countries there are official definitions, but they are not consistent on a global basis, nor even necessarily within countries. In addition, the underlying structure of different metropolitan areas varies: comparing a highly centralised city with an agglomeration of smaller settlements may not be very meaningful. Commuting patterns and other aspects of urban behaviour which underlie the metro area concept differ greatly around the world. Thus, all population figures for specific metro areas should be treated as interpretations rather than hard facts, and rankings and comparisons of metros should be treated with great caution. (All figures I am using are based on the official metropolitan area used by the city in question).
1 Tokyo, Japan 35,197,000
2 Seoul, South Korea 22,770,000
3 Mexico City, Mexico 19,411,000
4 New York City, USA 18,747,320
5 São Paulo, Brazil 18,333,000

As you can see, it is very difficult to answer this question, but I hope this information is helpfull.
