It is to be noted that 200.7 million pakistan population doesnt include GB and Azad kashmir. If their population is also included in Pakistan total stats , we will cross be around 220 million.
Azad kashmir only has about 4 million.

Come on.There is only 2 or 3 million afghanis.I am in favour of sending them back.Bengalis were part of pakistan until 1971.Some of them settled in karachi before this date.Rohingas should be allowed to stay given whats happeneing to them in burma.Keep in mind 207.7m include afghanis, bengalis and rohingas refugees. In reality growth rate is lower.
