Economic growth rate measure
The real economic growth rate is expressed as a percentage that shows the rate of change in a country's GDP, typically, from one year to the next. Another economic growth measure is the gross national product (GNP), which is sometimes preferred if a nation's economy is substantially dependent on foreign earnings. Gross Domestic Product measures the value of goods and services produced by a nation. Gross National Product measures the value of goods and services produced by a nation (GDP) and income from foreign investments. Some economists posit that total spending is a consequence of productive output.
