Explain the necessary conditions of takeoff and subsequent stages of development of a nation as propounded by Rostow.

Rostow’s Stages of Economic Growth: A Detailed Explanation

Rostow’s model outlines five stages, each characterized by specific economic, social, and political conditions. The transition between stages isn’t automatic; it requires specific preconditions to be met.

1. The Traditional Society

This is the pre-industrial stage, characterized by a subsistence agricultural economy, limited technology, a hierarchical social structure, and a fatalistic worldview. Production is primarily based on muscle power and animal labor. Social status is often ascribed, and change is slow. Political power is typically concentrated in the hands of landowners. There is limited urbanization and a low level of literacy.

• Necessary Conditions: Primarily agrarian economy, limited technological advancement, strong social hierarchies, limited mobility, and a lack of centralized political power focused on economic development.
• Example: Feudal Europe before the Industrial Revolution, or parts of rural Africa in the early 20th century.

2. Preconditions for Take-off

This stage involves the emergence of external demand for raw materials and agricultural products, which stimulates economic activity. Investments in infrastructure, such as transportation and communication, begin to take place. A national identity starts to develop, and there is a growing emphasis on education. Political elites begin to see economic development as a national priority. This stage is marked by the beginning of commercial agriculture and the development of a mining sector.

• Necessary Conditions: Development of transportation infrastructure (railways, ports), increased investment in education, emergence of a national market, political stability, and the development of a banking and financial system.
• Example: Brazil in the 19th century with its coffee exports, or India under British rule with the development of railways to facilitate raw material extraction.

3. The Take-off

This is the critical stage where rapid economic growth begins. A few leading sectors experience significant growth, driving overall economic expansion. Investment rates rise dramatically, often exceeding 10% of national income. Political and social institutions become more supportive of economic growth. Urbanization accelerates, and a new entrepreneurial class emerges. This stage is characterized by technological breakthroughs and the development of a modern industrial sector.

• Necessary Conditions: High rates of investment (over 10% of national income), development of one or more leading manufacturing sectors, political stability, a supportive legal framework, and a growing entrepreneurial class.
• Example: Great Britain during the Industrial Revolution (late 18th and early 19th centuries), or Japan during the Meiji Restoration (late 19th century).

4. Drive to Maturity

This stage sees the economy diversifying beyond the initial leading sectors. Technology is widely adopted, and the economy becomes more sophisticated. Investment shifts from leading sectors to infrastructure and social services. The economy becomes more integrated into the global economy. There is a growing emphasis on higher education and research and development.

• Necessary Conditions: Diversification of the economy, technological innovation, increased investment in education and research, development of a skilled workforce, and integration into the global economy.
• Example: Germany in the late 19th and early 20th centuries, or South Korea in the 1970s and 1980s.

5. Age of High Mass Consumption

This is the final stage, characterized by a high level of consumer spending and a focus on durable goods and services. The majority of the population enjoys a high standard of living. The economy is dominated by the service sector. There is a strong emphasis on social welfare and environmental protection. Political stability is generally high.

• Necessary Conditions: High levels of disposable income, a large middle class, a well-developed consumer market, a strong social welfare system, and a stable political environment.
• Example: The United States in the post-World War II era, or Western European countries today.
