China is not overpopulated, as you might think so because they are such a large nation and have a lot of habitable land (unlike Japan), that they can fit more people in. They get a lot of bad press for having a larger population, just because of the fact that larger numbers = people thinking that you are somehow responsible for most of the world's population issues
The Asian states that are more dense in population than the UK are:
1. Macau
3. Singapore
4. Hong Kong
11. Maldives
12. Bangladesh
17. Taiwan
18.
Mauritius19. Nepal
23. South Korea
33. India
38. Japan
44. Sri Lanka
45. Philippines
52. Vietnam
according to Wikipedia:
http://en.wikipedia.org/wiki/List_of_sovereign_states_and_dependent_territories_by_population_densityIf you notice that the gaps, all those countries are not Asian ie: countries that take the positions 5-10, 13-16, 20-22, 24-32, 34-37, 39-43, 46-51
The UK comes just under Vietnam at 53
The Asian countries that are less densely populated than the UK include
59. Pakistan
63. North Korea
80. China - and here's where around 20% of the world's population live
90. Thailand
92. Indonesia
101. Armenia
103. Azerbaijan
111. Turkey (arguably also in Europe)
117. Malaysia
129. East Timor
130. Burma
146. Georgia
149. Uzbekistan
154. Tajikistan
160. Afghanistan
186. Kyrgyzstan
187. Laos
220. Turkmenistan
227. Kazakhstan (also arguably partially in Europe)
240. Mongolia
And that's by using what I was told using conventional continents ie: America, Europe, Asia, Middle East, Australasia. Wikipedia seems to chuck in the entire Middle East in to Asia as well
http://en.wikipedia.org/wiki/List_of_sovereign_states_and_dependent_territories_in_AsiaUsing the above data, it's clear that there are 14 Asian nations that have a higher population density than the UK, but 20 Asian nations that have a lower population density than the UK - this is without me agreeing that the Middle East is just lumped as Asia
When you notice that China is considerably less densely populated than the UK, it's quite clear that you're just looking to make a provocative thread.
To be as densely populated as the UK, China would need:
2,458,409,355 people living in it, which is an extra 1,108,209,355 or an increase of around 82% in it's population, whereas trends would show that China, along with the rest of the world, is having less kids, not more.
China's fertility rate is: 1.16 according to Wikipedia
http://en.wikipedia.org/wiki/List_of_sovereign_states_and_dependent_territories_by_fertility_rateThe three most densely populated countries in the world include Macau, Hong Kong and Singapore. All three have a fertility rate of less than 1.1
Hong Kong fertility rate: 1.09
Macau fertility rate: 0.92
Singapore fertility rate: 0.78
