The World Population Prospects 2019: Highlights

17 June 2019. By the year 2050, there will be some 9.7 billion people living on Earth, says a UN population report. However, the overall growth rate will continue to fall, and more countries will have to adapt to the consequences of an ageing population.

“The World Population Prospects 2019: Highlights”, estimates that the next 30 years will see the global population add an extra 2 billion people to today’s figure of 7.7 billion, and, by the end of the century, the planet will have to sustain around 11 billion.

India will overtake China, sub-Saharan Africa population to doubleIndia is expected to show the highest population increase between now and 2050, overtaking China as the world’s most populous country, by around 2027. India, along with eight other countries, will make up over half of the estimated population growth between now and 2050.

The nine countries expected to show the biggest increase are India, Nigeria and Pakistan, followed by the Democratic Republic of the Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States of America. In all, the population of sub-Saharan Africa is expected to practically double by 2050.

People in the poorest countries still live 7 years less than the global average Life expectancy at birth for the world, which increased from 64.2 years in 1990 to 72.6 years in 2019, is expected to increase further to 77.1 years in 2050. While considerable progress has been made in closing the longevity differential between countries, large gaps remain. In 2019, life expectancy at birth in the least developed countries lags 7.4 years behind the global average, due largely to persistently high levels of child and maternal mortality, as well as violence, conflict and the continuing impact of the HIV epidemic.

“The World Population Prospects 2019: Highlights”, is published by the Population Division of the UN Department of Economic and Social Affairs (DESA) and provides a comprehensive overview of global demographic patterns and prospects. The report is based on population estimates from 1950 to the present for 235 countries or areas, underpinned by analyses of historical demographic trends. The 2019 revision also includes population projections to the year 2100, that reflect a range of plausible outcomes at the global, regional and country levels.

The main results are presented in a series of Excel files displaying key demographic indicators for each UN development group, World Bank income group, geographic region, Sustainable Development Goals (SDGs) region, subregion and country or area for selected periods or dates within 1950-2100. For advanced users who need to use these data in a database form or statistical software, it is recommended to use the CSV format for bulk download. Forthcoming special aggregates will also provide additional groupings of countries.
