The Rostow's stages of growth model is the most well-known example of the linear stages of growth model. Walt W. Rostow identified five stages through which developing countries had to pass to reach an advanced economy status: (1) Traditional society, (2) Preconditions for take-off, (3) Take-off, (4) Drive to maturity, (5) Age of high mass consumption. He argued that economic development could be led by certain strong sectors; this is in contrast to for instance Marxism which states that sectors should develop equally. According to Rostow's model, a country needed to follow some rules of development to reach the take-off: (1) The investment rate of a country needs to be increased to at least 10% of its GDP, (2) One or two manufacturing sectors with a high rate of growth need to be established, (3) An institutional, political and social framework has to exist or be created in order to promote the expansion of those sectors.
