@live2shop - GDP stands for gross domestic product. This is the total value of all products produced in a year's time in a country. GDP tells how well the country is doing in manufacturing. Some examples of final goods are toys, furniture, processed foods (like canned or frozen food, but not fresh food,like an apple), and computers.
The GNP measures the value of goods produced in our country and also what is produced by Americans in other countries. But all the items manufactured by the Chinese or Indians etc. are not counted in the GNP.
