Gross National Product
The per capita GNP, or Gross National Product, is the total value of all the goods and services produced by a country in one year, divided by the population. It is usually expressed in US dollars. The average per capita GNP (as of 2006) in developed countries with high-income economies, e.g. the United Kingdom, is about $23500. In developing countries with middle-income economies it is $2500. In developing countries with low-income economies, it is less than $400.
