The Netherlands is often called Holland. This is formally incorrect as North and South Holland in the western Netherlands are only two of the country's twelve provinces. As a matter of fact, many Dutch people colloquially use Holland as a synecdoche, being well aware of the widespread use of this name. For more on this and other naming issues see terminology of the Netherlands.
The Netherlands has a prosperous and open economy in which the government has reduced its role since the 1980s. Industrial activity is predominantly in food-processing, chemicals , petroleum refining (for example Royal Dutch Shell), and electrical machinery . In the north of the Netherlands, near Slochteren, one of the largest natural gas fields in the world is situated.
