In most situations, fertility and mortality are the main components of population change over time. In recent decades, there have been substantial declines in fertility in many parts of the world. Globally in 2019 the total fertility rate was 2.5, compared to 2.7 in 2000. In 2019, about one- fifth of countries or areas had a fertility level of four or more (figure 3); most of these countries were in sub-Saharan Africa. Almost half of countries globally had a total fertility rate lower than 2.1, the level required to achieve a long-run growth rate of zero for populations with low levels of mortality. Improvements in living conditions have contributed to lower mortality and increased life expectancy around the world. Globally, life expectancy at birth reached 72.6 years in 2019, up from 69.9 years in 2000. The largest gains in life expectancy at birth during this period occurred in sub-Saharan Africa (figure 4). Although the gap in longevity between less developed and more developed countries has been closing, life expectancy at birth in the least developed countries is still 7 years below the global average. Figure 5. Population by age and sex, 2019, 2050 and 2100 Changing levels of fertility, mortality and migration influence the age composition of populations. Globally and for individual countries or areas, the share of population above the age of 65 years is projected to increase, while the share below age 25 is projected to decrease between 2019 and the end of the century (figure 5). Already, most populations face decreasing numbers of working-age persons (from 25 to 64 years) relative to the number of older persons (65 years and over), and within a few decades this trend is expected for all countries and areas of the world. Globally, the potential support ratio, which equals the number of persons aged 25 to 64 years divided by the number aged 65 or over, is projected to decline from 6.3 in 2019 to 3.5 in 2050 and to reach 2.4 at the end of the century. Figure 6. Components of population change, 2010-2020 The map shows the relationship between two components of population change for the period 2010-2020: net migration (the difference in numbers of immigrants and emigrants) and natural increase (the difference in numbers of births and deaths). A majority of countries or areas experienced positive natural increase combined with either net emigration (108 countries or areas shown in light blue on the map) or net immigration (74, shown in dark blue). A smaller set of countries experienced negative natural increase together with either net emigration (10, shown in light green) or net immigration (9, shown in dark green). Thus, in 10 countries (Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Latvia, Lithuania, Moldova, Poland, Portugal and Romania), a net outflow of persons through international migration added to the impact of an excess of deaths over births, while in 9 countries (Belarus, Estonia, Germany, Hungary, Italy, Japan, the Russian Federation, Serbia and Ukraine), a net inflow of migrants helped to offset an excess of deaths over births.

In World Population Prospects 2019, the uncertainty of future trends is described using probabilistic prediction intervals, which form shaded cones around the bold line of the medium- variant projection (figure 1). Shaded areas in grey indicate that the global population is expected, with a probability of 80 per cent, to lie between 9.9 and 12.0 billion in 2100 and, with a probability of 95 per cent, between 9.4 and 12.7 billion. Although the medium variant anticipates that a global population of 10.9 billion people may still be growing in 2100 (albeit much more slowly than at present), there is an estimated probability of 27 per cent that the world’s population will stop growing and could even begin to shrink by the end of the century. According to the medium variant of World Population Prospects 2019, the global population is projected to continue to grow, rising from 7.7 billion in 2019 to 10.9 billion at the end of the century (bold line of figure 1). The world’s population, which is currently growing at a pace of 1.1 per cent per year, is expected to stop growing sometime around the end of the century and to stabilize at nearly 11 billion people. The anticipated change in population size differs greatly by region. While population growth will continue in most regions, the population of Europe is expected to decline from 0.75 billion in 2019 to 0.63 billion in 2100. Sub- Saharan Africa will experience the fastest growth, with its population projected to increase from just over a billion inhabitants in 2019 to around 3.8 billion in 2100 (figure 2).

The fertility level of a population is often described by the total fertility rate, which equals the average number of live births per woman over a lifetime (figure 3), while the mortality level can be summarized by life expectancy at birth, or the average age at death resulting from mortality conditions observed in a given year or period (figure 4). In most situations, fertility and mortality are the main components of population change over time. In recent decades, there have been substantial declines in fertility in many parts of the world. Globally in 2019 the total fertility rate was 2.5, compared to 2.7 in 2000.

Population projections entail a degree of uncertainty about future trends in population size. In World Population Prospects 2019, the uncertainty of future trends is described using probabilistic prediction intervals, which form shaded cones around the bold line of the medium-variant projection (figure 1). Shaded areas in grey indicate that the global population is expected, with a probability of 80 per cent, to lie between 9.9 and 12.0 billion in 2100 and, with a probability of 95 per cent, between 9.4 and 12.7 billion.

According to the medium variant of World Population Prospects 2019, the global population is projected to continue to grow, rising from 7.7 billion in 2019 to 10.9 billion at the end of the century (bold line of figure 1). The world’s population, which is currently growing at a pace of 1.1 per cent per year, is expected to stop growing sometime around the end of the century and to stabilize at nearly 11 billion people.

The designations employed in this publication and the material presented in it do not imply the expression of any opinion whatsoever 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. The term “country” as used in this publication also refers, as appropriate, to territories or areas.
In this table, data for countries or areas have been aggregated in six continental regions: Africa, Asia, Europe, Latin America and the Caribbean, Northern America, and Oceania. Further information on continental regions is available from https://unstats.un.org/unsd/methodology/m49/. Countries and areas are also grouped into geographic regions based on the classification being used to track progress towards the Sustainable Development Goals of the United Nations (see: https://unstats.un.org/sdgs/indicators/regional-groups/).
The designation of “more developed” and “less developed” regions is intended for statistical purposes and does not express a judgment about the stage reached by a particular country or area in the development process. More developed regions comprise all regions of Europe plus Northern America, Australia and New Zealand and Japan. Less developed regions comprise all regions of Africa, Asia (excluding Japan), and Latin America and the Caribbean as well as Oceania (excluding Australia and New Zealand).
The group of least developed countries includes 47 countries located in sub-Saharan Africa (32), Northern Africa and Western Asia (2), Central and Southern Asia (4), Eastern and South-Eastern Asia (4), Latin America and the Caribbean (1), and Oceania (4). Further information is available at http://unohrlls.org/about-ldcs/.
The group of Landlocked Developing Countries (LLDCs) includes 32 countries or areas located in sub-Saharan Africa (16), Northern Africa and Western Asia (2), Central and Southern Asia (8), Eastern and South-Eastern Asia (2), Latin America and the Caribbean (2), and Europe and Northern America (2). Further information is available at http://unohrlls.org/about-lldcs/.
The group of Small Island Developing States (SIDS) includes 58 countries or areas located in the Caribbean (29), the Pacific (20), and the Atlantic, Indian Ocean, Mediterranean and South China Sea (AIMS) (9). Further information is available at http://unohrlls.org/about-sids/.
The classification of countries or areas by income level is based on the gross national income (GNI) per capita as reported by the World Bank (June 2018). These income groups are not available for all countries or areas.

The Department of Economic and Social Affairs of the United Nations Secretariat is a vital interface between global policies in the economic, social and environmental spheres and national action. The Department works in three main interlinked areas: (i) it compiles, generates and analyses a wide range of economic, social and environmental data and information on which States Members of the United Nations draw to review common problems and take stock of policy options; (ii) it facilitates the negotiations of Member States in many intergovernmental bodies on joint courses of action to address ongoing or emerging global challenges; and (iii) it advises interested Governments on the ways and means of translating policy frameworks developed in United Nations conferences and summits into programmes 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 community with timely and accessible population data and analysis of population trends and development outcomes for all countries and areas of the world. To this end, the Division undertakes regular studies of population size and characteristics and of all three components of population change (fertility, mortality and migration). Founded in 1946, the Population Division provides substantive support on population and development issues to the United Nations 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. The work of the Division also contributes to strengthening the capacity of Member States to monitor population trends and to address current and emerging population issues.
About World Population Prospects 2019
The 2019 revision of the World Population Prospects is the twenty-sixth edition of the official United Nations population estimates and projections. It presents population estimates from 1950 to the present for 235 countries or areas, underpinned by analyses of historical demographic trends. This latest assessment considers 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 to the year 2100 that reflect a range of plausible outcomes at the global, regional and country levels.
