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, according to a new United Nations report launched today.
The World Population Prospects 2019: Highlights, which is published by the Population Division of the UN Department of Economic and Social Affairs, provides a comprehensive overview of global demographic patterns and prospects. The study concluded that the world’s population could reach its peak around the end of the current century, at a level of nearly 11 billion.
The report also confirmed that the world’s population is growing older due to increasing life expectancy and falling fertility levels, and that the number of countries experiencing a reduction in population size is growing. The resulting changes in the size, composition and distribution of the world’s population have important consequences for achieving the Sustainable Development Goals (SDGs), the globally agreed targets for improving economic prosperity and social well-being while protecting the environment.
The new population projections indicate that nine countries will make up more than half the projected growth of the global population between now and 2050: India, Nigeria, Pakistan, the Democratic Republic of the Congo, Ethiopia, the United Republic of Tanzania, Indonesia, Egypt and the United States of America (in descending order of the expected increase). Around 2027, India is projected to overtake China as the world’s most populous country.
The population of sub-Saharan Africa is projected to double by 2050 (99% increase).
