The global economic balance is gradually shifting towards Asia, and India could emerge as one of the biggest beneficiaries of this transformation. American economist Jeffrey Sachs believes India has the potential to become the world's largest economy by the end of the 21st century, driven by long-term demographic and economic trends.
Speaking at the World Symposium on "Ancient Wisdom for Modern Challenges" in Varanasi, Sachs highlighted the growing influence of Asia and Africa in shaping the future global economy. He suggested that India's population could be approximately twice that of China by 2100, strengthening its position in the global economic landscape.
His remarks offer a long-term perspective on India's economic opportunities and the changing structure of global power.
The Economic Centre of Gravity Is Moving Towards Asia
For much of the modern era, Western economies have dominated global trade, finance, technology and industrial development. However, the rapid economic growth of Asian countries has gradually changed that balance.
Sachs described the current period as a return of Asia to the centre of the global economy. He expects Asia and Africa together to account for approximately three-quarters of the world's population by 2100.
According to his projections, Asia could represent slightly less than half of global economic output, while Africa's share could rise significantly as its population and economies expand.
This shift suggests that future global growth will increasingly depend on developments across emerging economies rather than being concentrated in traditional Western markets.
India's Demographic Advantage
One of the central factors behind Sachs's outlook is India's population trajectory.
India is expected to remain one of the world's most populous countries throughout the century. Sachs believes its population could be roughly twice China's by 2100, creating a substantial demographic foundation for long-term economic expansion.
A large population can support economic growth through a broader workforce, domestic consumption and expanding markets.
However, population size alone does not guarantee economic success. India will also need to improve education, workforce skills, healthcare, productivity and employment opportunities to translate its demographic potential into sustainable growth.
The quality of human capital will be just as important as the size of the population.
Infrastructure and Investment Will Shape India's Future
Economic growth on the scale Sachs describes will require sustained investment in infrastructure and productive capacity.
Transport networks, energy systems, digital connectivity, manufacturing facilities and urban infrastructure will influence how effectively India can support businesses and create employment.
Sachs also acknowledged the role of large Indian businesses in the country's infrastructure development and economic transformation. He highlighted the responsibilities of family-led enterprises, arguing that businesses should balance commercial performance with wider social obligations.
For India, continued investment in infrastructure, technology and industrial development could help strengthen its position in international markets.
A Multipolar World, Not a Single Global Power
Sachs's outlook extends beyond India's economic rise. He believes the world is moving towards a multipolar system in which no single country or region will dominate.
He argued that India, China and other emerging economies will play increasingly important roles in shaping international economic and political decisions.
He also emphasised the importance of cooperation between India and China. Despite their differences, stronger engagement between the two Asian powers could contribute to trade, investment, regional stability and a more balanced international order.
This perspective challenges the traditional idea that global influence must remain concentrated among a small group of Western powers.
The Challenges India Must Address
Although Sachs's forecast is optimistic, becoming the world's largest economy by 2100 is not guaranteed.
India will need to address several long-term challenges:
Employment generation: Creating productive jobs for a large and changing workforce.
Education and skills: Preparing people for technology-driven industries and future business requirements.
Infrastructure development: Expanding transport, energy, manufacturing and digital infrastructure.
Innovation: Strengthening research, entrepreneurship and technology development.
Inclusive growth: Ensuring economic progress improves opportunities and living standards across different regions and communities.
The ability to address these challenges will determine how much of India's demographic and economic potential can be realised.
Conclusion: India's Next Century Could Reshape the Global Economy
Jeffrey Sachs's projection presents an ambitious vision of India's position in the global economy by 2100. His comments reflect broader demographic and economic trends that point towards Asia's growing influence and a more multipolar world.
However, the forecast should be viewed as a long-term possibility rather than a certainty. Economic leadership will depend on productivity, institutional strength, infrastructure, education, innovation and the ability to sustain inclusive development.
If India can convert its population advantage into a skilled workforce, stronger industries and sustained economic growth, its influence in the global economy could expand significantly over the coming decades.
The question is no longer simply how quickly India can grow today, but how effectively it can build the foundations for economic leadership in the century ahead.
