Rostow's Stages of Development proposes that countries pass through 5 stages as their economies grow: 1) Traditional Society based on subsistence agriculture; 2) Preconditions for Take-Off as manufacturing develops and technology/trade increase; 3) Take-Off period of extensive growth and industrialization; 4) Drive to Maturity as standards of living rise through increased technology and economic diversification; 5) High Mass Consumption as individual incomes rise beyond essentials and consumer demand grows. The model is criticized for assuming all countries develop the same way without variations, while its advantage is being a widely cited and respected development theory.
