The book the stage of economic growth (written by W. W. Rostow) was an attempt to explain how:

YOU SAID I SHOULD EXPLAIN SO THIS IS WHAT I GOT. 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:[1]

1.The traditional society

2.The preconditions for take-off

3.The take-off

4.The drive to maturity

5.The age of high mass-consumption

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.
