By the year 2100, Which Country Will be the World's Number 1 Superpower?

[ingemann]

I think it may be meaningless to talk about a "World's Number 1 Superpower" by 2100, instead we may have several powers, with no clear nr. 1.

Of course that depend on whether EU successful federate. If EU federate it will be at very least a equal to USA, if it doesn't USA will keep its position as the leader of the West, which will mean that they're nr. 1. But even if EU federate, I think it and USA will keep a close alliance, which make the west dominating.

As for China and India, I don't see India really deal with the institutional problems they suffer from, so I think they will be more of the 22nd century's Brazil than its USA. China have its own problems, but at very least they have a central government, which isn't wagged by the tail.

A interesting aspect is that Nigeria will likely hit 1 billion by 2100, while several other west African states will have population in the hundreds of millions. So we may be talking about the rise of Africa in the same way as people suggest a rise of Asia today.

Nigeria is even more unworkable than India though due to its north south divide.

Yes but that won't keep people from talking about its rise, just as they talk about India today.

It won't it have too low a population and population growth to be nr. 1.

Not going to happen, at most we see a federal South America, but I'm doubtful for even that.
