Walt W. Rostow's theory outlines five distinct stages of economic development that nations progress through.
According to Rostow's model, the stage that specifically marks the interval when old resistance to steady economic growth is finally overcome is the take-off stage. This is the third of the five stages.
The five stages are:
During the take-off stage, key sectors experience rapid growth, investment increases significantly, and the economy overcomes structural limitations, leading to sustained development.
