World Population Prospects 2017

The United Nations population estimates and projections form a comprehensive set of demographic data to assess population trends at the global, regional and national levels. They are used in the calculation of many of the key development indicators commonly used by the United Nations system, including for more than one third of the indicators used to monitor progress towards the achievement of the Sustainable Development Goals. The 2019 revision of the World Population Prospects is the twenty-sixth edition of the official United Nations population estimates and projections, which have been prepared since 1951 by the Population Division of the Department of Economic and Social Affairs. The 2019 revision presents population estimates from 1950 until the present for 235 countries or areas, which have been developed through country-specific analyses of historical demographic trends. It builds on previous revisions by incorporating additional results from the 2010 and 2020 rounds of national population censuses as well as information from vital registration and recent nationally representative household sample surveys. The 2019 revision also presents population projections to the year 2100 that reflect a range of plausible outcomes at the global, regional and country levels. These Highlights summarise key population trends described by the estimates and projections presented in World Population Prospects 2019.

The United Nations population estimates and projections form a comprehensive set of demographic data to assess population trends at the global, regional and national levels. The 2017 Revision of World Population Prospects represents the latest global set of demographic estimates and projections prepared by the Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat. It constitutes the twenty-fifth round of global population estimates and projections produced by the Population Division since 1951. This volume of the 2017 Revision presents the comprehensive tables of the official United Nations population estimates and projections, displaying key demographic indicators for selected periods or dates from 1950 to 2100, for the world, development groups, regions, subregions, and countries or areas with more than 90,000 inhabitants in 2017. For countries or areas with fewer than 90,000 inhabitants in 2017, only figures related to population size and growth are provided. In all data tables, figures for 1950-2015 are estimates and those thereafter are projections. The projections are presented for the medium, high, low and constant-fertility variants.

The 2017 Revision of World Population Prospects represents the latest global set of demographic estimates and projections prepared by the Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat. It constitutes the twenty-fifth round of global population estimates and projections produced by the Population Division since 1951. This volume of the 2017 Revision presents the demographic profiles of the official United Nations population estimates and projections. The demographic profiles display key demographic indicators for selected periods or dates between 1950-2100, for the world, development groups, regions, subregions and countries or areas with more than 90,000 inhabitants in 2017. In all tables and figures, values for 1950-2015 are estimates and those thereafter are projections (medium variant). For each country or area, the volume also provides a brief description of the data sources and demographic methods that were used to derive the base-year estimates

World Population: Past, Present, & Future uses a multidisciplinary approach to investigate in depth on important aspects of the evolution of world population not well addressed previously. The authors from the Universidad Autonoma, Madrid (Spain), professors Julio A Gonzalo, Manuel Alfonseca, and Félix-Fernando Muñoz, point out that the recent pronounced growth in world population (accompanied by an even more pronounced growth in agricultural production) was due mainly to the increase of life expectancy and not to the (inexistent) growth in fertility rate. Using a "rate equations" approach for the first time, they describe population trends and forecast the possibility of steps up (or down) in population rather than the exponential growth predicted by UN demographers around 1985 and thereafter. This book provides a new perspective that our planet is not overpopulated and could, in fact, house a considerably larger population.

Accurate, consistent and timely data on global trends in population age structure are critical for assessing current and future needs with respect to population ageing and for setting policy priorities to promote the well-being of the growing number and share of older persons in the population. This publication presents the highlights of the World Population Ageing 2017 report, which summarizes the trends in population ageing drawn from the latest United Nations estimates and projections of population by age and sex, as published in World Population Prospects: The 2017 Revision. The present Highlights includes a special focus on trends in the household living arrangements of older persons - whether alone, with a spouse or with own children - reflecting newly compiled estimates from the United Nations Database on the Living Arrangements of Older Persons, 2017.

The 2015 Revision will build on the previous revision by incorporating the findings of new population censuses and specialized demographic surveys, which have been published since the previous revision. This comprehensive review of worldwide demographic trends and future prospects is essential for assessing the degree of progress made in achieving the Millennium Development Goals (MDGs) and to guide policies aimed at achieving the new post-2015 development agenda, which Member States will adopt this fall. The full results of the 2015 revision will be made available in the form of a two volume report.
