World Population Prospects 2019: Highlights
17 June 2019
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 World Population Prospects 2019: Highlights presents the main results of the 26th round of the UN’s global population estimates and projections. The report includes updated population estimates from 1950 to the present for 235 countries or areas, based on detailed analyses of all available information about the relevant historical demographic trends. The latest assessment uses the results of 1,690 national population censuses conducted between 1950 and 2018, as well as information from vital registration systems and from 2,700 nationally representative sample surveys. The 2019 revision also presents population projections from the present until 2100, depicting a range of possible or plausible outcomes at the global, regional and country levels.
