Rostow's model outlines 5 stages of economic growth:
1. Traditional society dominated by agriculture and family/caste systems with obsolete techniques.
2. Preconditions for take-off including a spread of infrastructure and technical revolution in agriculture.
3. Take-off period of 20-30 years where industries generate savings/investment and self-sustaining growth occurs.
4. Drive to maturity lasting 40+ years where modern technology is applied widely and economic development becomes automatic.
5. Age of high mass consumption where attention shifts to demand/consumption and standards of living increase substantially.
