Netherlands is the main country in the Kingdom of the Netherlands, which includes Caribbean countries Aruba, Curaçao, and Sint Maarten. An older designation for the country is "Holland", although this really only applies to North Holland and South Holland, two of its twelve provinces.
The Netherlands is small (41,543 sq. km) and densely populated, yet is the world's second largest exporter of agricultural products. Only 50% of the country is more than 1 m above sea level.
International rankings place the Netherlands very high, and it is considered among the happiest countries on earth.
