Around 2027, India is projected to overtake China as the world’s most populous country, while China’s population is projected to decrease by 31.4 million, or around 2.2 per cent, between 20. China (1.44 billion) and India (1.39 billion) remain the two most populous countries of the world, both with more than 1 billion people, representing 19 and 18 per cent of the world’s population, respectively. Sixty-one per cent of the global population lives in Asia (4.7 billion), 17 per cent in Africa (1.3 billion), 10 per cent in Europe (750 million), 8 per cent in Latin America and the Caribbean (650 million), and the remaining 5 per cent in Northern America (370 million) and Oceania (43 million). These trends will have far-reaching implications for generations to come. This dramatic growth has been driven largely by increasing numbers of people surviving to reproductive age, and has been accompanied by major changes in fertility rates, increasing urbanization and accelerating migration. The world’s population is expected to increase by 2 billion persons in the next 30 years, from 7.7 billion currently to 9.7 billion in 2050 and could peak at nearly 11 billion around 2100. In October 2011, the global population was estimated to be 7 billion. A global movement 7 Billion Actions was launched to mark this milestone. It reached 5 billion in 1987 and 6 billion in 1999. In 1950, five years after the founding of the United Nations, world population was estimated at around 2.6 billion people.
