Study Notes
Overview
The development of emerging countries is a complex, interconnected process. Examiners want you to understand that economic growth does not happen in isolation—it is deeply linked to demographic changes (like falling birth rates and rising life expectancy) and social transformations (like better education and a growing middle class). This topic requires you to understand these processes, explain how they interact, and evaluate both the positive and negative impacts of rapid development. We will use India as our primary case study, as it provides excellent, mark-winning data for your exam answers.
Key Economic Processes
Sectoral Shift
Date(s): 1990 to present
What happened: India has transitioned from an economy dominated by the primary sector to one driven by the tertiary and quaternary sectors.
Why it matters: This shift has driven massive GDP growth and created a new middle class, but it has also led to uneven development between urban tech hubs and rural agricultural areas.
Specific Knowledge: In 1990, 60% of the workforce was in the primary sector. By 2024, the tertiary sector employed 55% of the workforce. GDP grew from 500 billion in 2000 to3.7 trillion in 2024.
Trade and Investment
Date(s): Post-1991 economic reforms
What happened: India opened its economy to foreign direct investment (FDI) and transnational corporations (TNCs).
Why it matters: International trade integrated India into the global economy, creating jobs and transferring technology.
Specific Knowledge: TNCs like Amazon and Apple invest in India, while domestic TNCs like Tata and Infosys operate globally.
Key Demographic Processes
Demographic Transition
Date(s): 1990 to present
What happened: India's population structure has changed from a classic wide-base pyramid to a more rectangular shape with a large working-age population.
Why it matters: This creates a 'demographic dividend'—a large workforce that can drive economic growth and productivity.
Specific Knowledge: Birth rates fell from 32/1000 in 1990 to 17/1000 in 2024. Life expectancy rose from 58 to 70 years. The total population reached 1.44 billion.
Key Social Processes
Rise of the Middle Class and Inequality
Date(s): Ongoing
What happened: While 300 million people have entered the middle class, inequality remains high.
Why it matters: Development is uneven. Urban 'cores' gain wealth rapidly, while rural 'peripheries' lag behind.
Specific Knowledge: India's Gini coefficient is approximately 0.35. Literacy rates improved from 52% (1990) to 77% (2024).
Managing the Impacts of Development
Rapid development brings both benefits and severe costs.
Positive Impacts: Higher incomes, better healthcare, improved education, global influence.
Negative Impacts: Severe air pollution (Delhi often exceeds WHO limits by 20x), water scarcity (affecting 600 million), and the growth of informal settlements (65 million people).
Management Strategies: The government uses public investment to manage these impacts, such as the Smart Cities Mission and the Swachh Bharat (Clean India) Mission to improve sanitation.
