As per dual sector theory of economics, the modern service or industrial sector utilizes the surplus labor in the agricultural or primary sector as its source of growth, along with capital generated by the investment of savings, to expand its production and thus the gross output of the economy. As the Services or industrial (modern) sector expands in importance, there is a concomitant reduction in the percentage contribution to gross output by the agricultural sector. This growth process thus generally requires the movement of labor from rural areas to the urban areas with a decline of the rural population as a percentage of the national population. Paradoxically, the rural population and percentage of agriculture employment to total employment play an important role in the growth of agriculture. The following macro-economic variables play an important role in predicting the GDP of a nation: Population growth (annual %), Inflation, consumer prices (annual %), Rural population (% of total population), Exports of goods and services (% of GDP), Ratio of Exports to Imports of agricultural products (EXIM), Foreign Direct Investment, net (FDI), External debt stocks (% of GNI), and Life expectancy at birth, total (years).
