Question

3. What accounts for most of the population growth of Europe?
(Points : 2)
A high birthrate

A negative fertility rate

A negative migration rate

A positive migration rate

Answer 1

Well, it can't be B or C.
And most Europeans would migrate to America.
It is most likely A.

Answer 2

Its because many, many migrants are moving to the European nations, believe it or not. So much, in fact, countries like England want to put a cap on immigration.

Answer 3

"If the current fertility rate of around 1.5 births per woman persists until 2020, negative momentum will result in 88 million fewer people in 2100, if one assumes constant mortality and no net migration," the researchers say. The EU population in 2000 was about 375 million.

Therefore according to this fact and prediction as the population will decline, it certainly proves that only "positive migration" is the main reason behind its stable population growth in the European countries right now.
