2010 Gross Domestic Product / Gross Metropolitan Product
Long Island’s economic trend reflects the national recession.
Why is this important?
The Gross Domestic Product (GDP) is a measure of the extent of economic activity within a defined geographical region or within a sector of a defined economic region. When referencing a defined metropolitan area it is sometimes referred to as the Gross Metropolitan Product (GMP). Essentially the GDP/GMP measures the economic output of a region and can be used to compare overall economic activities across regions, or the contributions of various sectors.
