What is the primary difference between Gross National Product (GNP) and Gross Domestic Product (GDP)?

GNP is always higher than GDP for any given country.

GNP includes production by a country's citizens regardless of location, while GDP includes all production within a country's borders.

GNP measures only the production of goods, while GDP measures both goods and services.

GNP includes only domestic production, while GDP includes both domestic and foreign production.
