> Netherlands: ~7 million

Erm, population of The Netherlands is 16.8million. See http://countryeconomy.com/demography/population/netherlands

7 million is about the population of the Randstad, the agglomeration in the west of Netherland that contains the major cities (Amsterdam, Rotterdam, The Hague, Utrecht) as well as numerous minor ones, grown together into what's practically one giant city.

But there's still 10 million people living in the rest of the country.
