Why is the swedish population so small?

Question

Why is the swedish population so small?

Answer 1

Because Sweden is on the north and it is very cold so almost nobody live northern of Stocholm.

Answer 2

It's not actually that small if you look at all Eurpoean countries on a population per country basis

It has a higher population than all of it's neighbours (Denmark, Finland, Norway)

Traditionally it was not a popluar place to live of course because of the climate, but in recent years, due to the high standard of living, it is actually very attractive to migrants.  Indeed "Of the 2004 population, 1.1 million, or 12%, were foreign-born and approximately 16.7% (1.53 million) had at least one parent born abroad or were themselves born abroad"

Without the relatively recent measures to tighten immigration policies, the population would actually be a lot larger than what it is.
