New population projections reveal dramatic shifts among the world’s six largest countries by 2075, highlighting India’s continued rise, China’s decline, and Nigeria’s rapid growth. These forecasts, compared to 1970 figures, underscore the evolving demographic landscape and its potential implications for global economics, resources, and geopolitics.
India:
- By 2075, India is projected to lead with a population of 1.678 billion, a significant increase from its 551 million in 1970. Already the world’s most populous country as of 2023, India’s growth reflects its relatively high fertility rates and young population, though it faces challenges in infrastructure and resource management.

China:
- China, which had 812 million people in 1970, is expected to see its population shrink to 1.035 billion by 2075. This decline follows decades of strict family planning policies, like the one-child policy, and a rapidly aging population, posing economic challenges as the workforce shrinks.
Nigeria:
- Nigeria’s population is forecasted to surge to 491 million by 2075, up from just 55 million in 1970. This nearly ninefold increase highlights Nigeria’s high fertility rates and youthful demographic, positioning it as a future economic powerhouse in Africa, though it must address education and job creation to harness this growth.
Pakistan:
- Pakistan is projected to reach 452 million by 2075, a sharp rise from 58 million in 1970. Rapid population growth in Pakistan raises concerns about resource strain, particularly water and food security, in an already densely populated region.
United States:
- The U.S. population is expected to grow modestly to 389 million by 2075, up from 199 million in 1970. Immigration and steady birth rates contribute to this growth, though an aging population may strain social services in the coming decades.
Indonesia:
- Indonesia’s population is forecasted to increase to 316 million by 2075, compared to 114 million in 1970. While growth is slower than in other developing nations, Indonesia’s large population continues to make it a key player in Southeast Asia.
These projections highlight the need for tailored policies to address each country’s unique demographic trajectory, from aging populations in China to youth booms in Nigeria and Pakistan.
