Iceland's population to reach 400k this year, 26 years earlier than projected

That must be one of the worst predictions I have ever seen with dude predicting Iceland will reach population of four hundred thousand by 2050. It reached that in sixteen years, when the dude predicted in 2008, that it will take 42 years to reach population of four hundred thousand. Looking at the recent population increase trends in Iceland with ten thousand population increase in one year, that is massive for tiny country like Iceland with tiny population. I could personally predict, that Iceland reach population of 500 thousand in 2035 and 600 thousand before 2050, if it keeps its population increase trend of ten thousand new people per year.

Disappointingly the article does not say anything about why this is happening.
