Rostow's stages of growth

Rostow's Stages of Economic Growth model is one of the major historical models of economic growth. It was published by American economist Walt Whitman Rostow in 1960. The model postulates that economic growth occurs in five basic stages, of varying length:

Rostow's model is one of the more structuralist models of economic growth, particularly in comparison with the "backwardness" model developed by Alexander Gerschenkron, although the two models are not mutually exclusive.

Rostow argued that economic take-off must initially be led by a few individual economic sectors. This belief echoes David Ricardo's comparative advantage thesis and criticizes Marxist revolutionaries' push for economic self-reliance in that it pushes for the "initial" development of only one or two sectors over the development of all sectors equally. This became one of the important concepts in the theory of modernization in social evolutionism.

Below is a detailed outline of Rostow's Five Stages of Growth:

Rostow claimed that these stages of growth were designed to tackle a number of issues, some of which he identified himself, writing:

"Under what impulses did traditional, agricultural societies begin the process of their modernization? When and how did regular growth become a built-in feature of each society? What forces drove the process of sustained growth along and determined its contours? What common social and political features of the growth process may be discerned at each stage? What forces have determined relations between the more developed and less developed areas; and what relation if any did the relative sequence of growth bear to outbreak of war? And finally where is compound interest taking us? Is it taking us to communism; or to the affluent suburbs, nicely rounded out with social overhead capital; to destruction; to the moon; or where?"

Rostow asserts that countries go through each of these stages fairly linearly, and set out a number of conditions that were likely to occur in investment, consumption, and social trends at each state. Not all of the conditions were certain to occur at each stage, however, and the stages and transition periods may occur at varying lengths from country to country, and even from region to region.
