Identify key components of economic growth

Economic growth, as measured by GDP, is driven by two components: population growth and labor productivity. Labor productivity reflects the capacity for increased output from the existing quantity of labor in the economy. Various government agencies and independent analysts produce measures of labor productivity.

The key components are labour productivity and population growth as measured by GDP. Labor productivity measures and shows how much an increase in output has resulted from the current quantity of labor in the economy. For population growth, the higher the population, it is taken to mean presence of labor. However this depends on other factors such as total employment and the type of labor force required.
