The Department of Economic and Social Affairs of the United Nations Secretariat is a vital interface between globalpolicies in the economic, social and environmental spheres and national action. The Department works in threemain interlinked areas: (i) it compiles, generates and analyses a wide range of economic, social and environmentaldata and information on which States Members of the United Nations draw to review common problems and takestock of policy options; (ii) it facilitates the negotiations of Member States in many intergovernmental bodies onjoint courses of action to address ongoing or emerging global challenges; and (iii) it advises interested Governmentson the ways and means of translating policy frameworks developed in United Nations conferences and summits intoprogrammes at the country level and, through technical assistance, helps build national capacities.The Population Division of the Department of Economic and Social Affairs provides the international communitywith timely and accessible population data and analysis of population trends and development outcomes for allcountries and areas of the world. To this end, the Division undertakes regular studies of population size andcharacteristics and of all three components of population change (fertility, mortality and migration). Founded in1946, the Population Division provides substantive support on population and development issues to the UnitedNations General Assembly, the Economic and Social Council and the Commission on Population and Development.It also leads or participates in various interagency coordination mechanisms of the United Nations system. Thework of the Division also contributes to strengthening the capacity of Member States to monitor population trendsand to address current and emerging population issues.NotesThe designations employed in this report and the material presented in it do not imply the expression of any opinionswhatsoever on the part of the Secretariat of the United Nations concerning the legal status of any country, territory,city or area or of its authorities, or concerning the delimitation of its frontiers or boundaries.This report is available in electronic format on the Division’s website at www.unpopulation.org.

PREFACEThe 2017 Revision of World Population Prospects represents the latest global set of demographic estimates andprojections prepared by the Population Division of the Department of Economic and Social Affairs of the UnitedNations Secretariat. It constitutes the twenty-fifth round of global population estimates and projections produced bythe Population Division since 1951.This volume of the 2017 Revision presents the comprehensive tables of the official United Nations populationestimates 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 in2017. For countries or areas with fewer than 90,000 inhabitants in 2017, only figures related to population size andgrowth are provided. In all data tables, figures for 1950-2015 are estimates and those thereafter are projections. Theprojections are presented for the medium, high, low and constant-fertility variants. The tables are accompanied by anexecutive summary.To depict the uncertainty of future demographic trends, the Population Division has developed probabilisticprojections for all countries and areas of the world. It should be stressed that making projections to 2100 is subject toa high degree of uncertainty, especially at the country level. In that regard, users are invited to focus not only on theoutcomes of the medium variant, which for each country corresponds to the median of several thousand projectedtrajectories of specific demographic components, but also to the associated prediction intervals that provide anassessment of the uncertainty inherent in such projections. Detailed information on the uncertainty bounds fordifferent components at the country level is available on the website of the Population Division,www.unpopulation.org (also ic/). The data tables of this volumedo not include the probabilistic projections and are restricted to deterministic projection variants included in earlierrevisions of World Population Prospects.The detailed results of the 2017 Revision are made available through a variety of media. The website of thePopulation Division provides access to an extended set of data organized in Excel files as well as to an interactivedatabase that enables users to obtain specific information on selected countries or regions.The results of the 2017 Revision are presented in two volumes. In addition to this volume, the second volumecontains demographic profiles presenting time series and plots of selected indicators, covering the period from 1950to 2100, for each country or area, as well as for development groups, income groups, regions and subregions. Thesecond volume also provides a brief description of the data sources and methods used to derive the estimates foreach country or area.In preparing the 2017 Revision, the Population Division benefitted from the collaboration of the regionalcommissions, especially the Economic Commission for Latin America and the Caribbean, and of specializedagencies and other relevant bodies of the United Nations system, including UNAIDS, UNICEF, UNHCR and theWorld Bank. The Statistics Division of the Department of Economic and Social Affairs, through its United NationsDemographic Yearbook and accompanying databases, provided access to official national population statistics usedin the preparation of the 2017 Revision. The Population Division also acknowledges the assistance and cooperationof the organizations responsible for the Demographic and Health Surveys, the Multiple Indicator Cluster Surveys,the Human Mortality Database, and IPUMS-International, and of the many national statistical offices that have madeavailable data and reports for recent censuses and surveys to inform the development of the estimates presented inthis report. The Population Division is grateful for the contributions made by these entities and accepts responsibilityfor any errors in the manipulation or interpretation of the information provided.The 2017 Revision of the World Population Prospects was prepared by a team led by François Pelletier,including Lina Bassarsky, Helena Cruz Castanheira, Danan Gu, John Kanakos, Neena Koshy, Igor Ribeiro,Cheryl Sawyer, Thomas Spoorenberg and Guangyu Zhang. The team is grateful to other colleagues in thePopulation Division for the support they have provided.United Nations Department of Economic and Social Affairs/Population DivisionWorld Population Prospects: The 2017 Revision, Volume I: Comprehensive Tablesiii

The term“country” as used in this publication also refers, as appropriate, to territories or areas.More developed regions comprise all regions of Europe plus Northern America, Australia/New Zealand and Japan.Less developed regions comprise all regions of Africa, Asia (excluding Japan), and Latin America and theCaribbean as well as Melanesia, Micronesia and Polynesia. Countries or areas in the more developed regions aredesignated as “developed countries”. Countries or areas in the less developed regions are designated as “developingcountries”.The group of least developed countries, as defined by the United Nations General Assembly in its resolutions(59/209, 59/210, 60/33, 62/97, 64/L.55, 67/L.43, 64/295 and 68/18) included 47 countries in June 2017: 33 inAfrica, 9 in Asia, 4 in Oceania and one in Latin America and the Caribbean.

Nutrition is an integral aspect of animal husbandry and the pet food trade now makes up a substantial proportion of the animal care industry. Providing animals with the appropriate feeds in the correct quantities, taking into account factors such as species, breed, activity level and age, requires an understanding of the fundamentals of animal nutrition. A balanced diet is vital to the .
