Rostow's stages of economic growth model outlines 5 stages of development: 1) traditional society, 2) preconditions for take-off, 3) take-off, 4) drive to maturity, and 5) age of high mass consumption. The take-off stage involves investment increasing to over 10% of GDP, triggering sustained economic growth. During drive to maturity, new industries replace old ones and agriculture declines as countries industrialize. In the final stage, per capita incomes rise enough for widespread consumer goods consumption. The document discusses these stages and their application to understanding rural development.
