3. Rotterdam-The Hague, Netherlands — 12.943 points
Both Rotterdam and the Hague, forming one metro area, have the same roughly 50% native Dutch population as Amsterdam. The Hague is best known as the location of the International Criminal Court, but about 600,000 people who apparently aren’t affected by the “not in my backyard” mentality also live there, including the King and Queen of the Netherlands and a surprising mix of people from around the world. The two cities are home to tens of thousands of people born in the remnants of Dutch colonialism. Rotterdam is technically at sea level, and much of the Netherlands is at or below sea level — the government plans extensively to protect from floods and other problems.
