Papua New Guinea.Population projections are attempts to show how the human population living today will change in the future. Based on this, the UN Population Division expects world population, currently at 7. About two thirds of the predicted growth in population between and will take place in Africa. Because of population momentum the global population will continue to grow, although at a steadily slower rate, for the remainder of this century, but the main driver of long-term future population growth will be the evolution of the global average fertility rate.

The table below shows that from tothe bulk of the world's population growth is predicted to take place in Africa: of the additional 1. For example, the UN projects that the population of Nigeria will surpass that of the United States by about The population of the More Developed regions is slated to remain mostly unchanged, at 1. All population growth comes from the Less Developed regions.

The table below breaks out the UN's future population growth predictions by region [7]. Between and the end of this century, the UN predicts that all six regions will experience declines in population growth, that by the end of the century three of them will be experiencing population decline, and the world will have reached zero population growth. The median scenario of the UN World Population Prospects [8] predicts the following populations per region in compared to population inin billions:.

Projections of population reaching more than one generation into the future are highly speculative: Thus, the United Nations Department of Economic and Social Affairs report of projected the world population to peak at 9. The UN Population Division report of projects world population to continue growing, although at a steadily decreasing rate, and to reach This projected growth of population, like all others, depends on assumptions about vital rates.

For example, the UN Population Division assumes that Total fertility rate TFR will continue to decline, at varying paces depending on circumstances in individual regions, to a below-replacement level of 1. Between now andregions with TFR currently below this rate, e. Europe, will see TFR rise. Other assumptions can produce other results. Some of the authors of the UN report assumed that life expectancy would rise slowly and continuously.

The projections in the report assume this with no upper limit, though at a slowing pace depending on circumstances in individual countries. Bythe report assumed life expectancy to be from 66 to 97 years, and by from 87 to years, depending on the country. Based on that assumption, they expect that rising life expectancy will produce small but continuing population growth by the end of the projections, ranging from 0.

The hypothetical feasibility and wide availability of life extension by technological means would further contribute to long term beyond population growth. Evolutionary biology also suggests the demographic transition may reverse itself and global population may continue to grow in the long term. The population of a country or area grows or declines through the interaction of three demographic drivers: fertility, mortality, and migration. Fertility is expressed as the total fertility rate TFRa measure of the number of children on average that a woman will bear in her lifetime.

With longevity trending towards uniform and stable values worldwide, the main driver of future population growth will be the evolution of the fertility rate.

Where fertility is high, demographers generally assume that fertility will decline and eventually stabilize at about two children per woman. During the period —, the average world fertility rate was 2. In the medium variant, global fertility is projected to decline further to 2. If the mortality rate is relatively high and the resulting life expectancy is therefore relatively low, changes in mortality can have a material impact on population growth.

Where the mortality rate is low and life expectancy has therefore risen, a change in mortality will have much less an effect. Because child mortality has declined substantially over the last several decades, [2] Global life expectancy at birth, which is estimated to have risen from 47 years in — to 67 years in —, [20] is expected to keep rising to reach 77 years in — The population of 31 countries or areas, including Ukraine, Romania, Japan and most of the successor states of the Soviet Unionis expected to be lower in than in Migration can have a significant effect on population change.

The largest migratory outflows have been in response to demand for workers in other countries Bangladesh, Nepal and the Philippines or to insecurity in the home country Myanmar, Syria and Venezuela. Belarus, Estonia, Germany, Hungary, Italy, Japan, the Russian Federation, Serbia and Ukraine have experienced a net inflow of migrants over the decade, helping to offset population losses caused by a negative natural increase births minus deaths.

Walter Greiling projected in the s that world population would reach a peak of about nine billion, in the 21st century, and then stop growing after a readjustment of the Third World and a sanitation of the tropics. Estimates published in the s tended to predict that the population of Earth would stop increasing around Bythe world's population will increase by a third—it's projected to reach 9.

The new data sheet from the Washington, D. Bythe PRB projects that the world's population will hit 10 billion. Currently, there are 7. Here's a closer look at some of the data. Byit's seen falling into second place behind India, as its population dips slightly to 1. Russia and Mexico, which are now the ninth and tenth most populous countries, will not be in the top 10 in The Democratic Republic of the Congo is expected to be the eighth most populous country, while Egypt will occupy the 10th spot.

The population of these 48 countries34 of which are in Africa, will double in the next 34 years. Romania, which has one of the world's lowest fertility rates, will see the largest fall in population. That's more that two-and-a-half times the projected population of the African continent, which is set to reach 2. The Americas will have 1. Europe will see its population decline from million to million. The Population Reference Bureau says data came from official country statistical yearbooks and a variety of U.

Statistics Division. It also used the U. The Population Reference Bureau says"The accuracy of population projections depends primarily on the accuracy of the underlying assumptions. World Population growth Asia Africa China.Every individual value has been rounded to the nearest thousand, to assure data coherence, particularly when adding up sub totals.

Although data from specific statistical offices may be more accurate, the information provided here has the advantage of being homogeneous. This means that demographic estimates for the next five or even ten years can be more accurate than the projected evolution of GDP over the same time period which may also be distorted by inflation.

However, no projected population figures can be considered exact. As the IDB states, "figures beyond the years should be taken with caution", as the "census way towards those years has yet to be paved". Thus projections can be said to be looking through a kind of "cloudy glass" [1] or a "misty window": realistically, the projections are " guesstimates ".

To make things complicated, not all countries carry out censuses regularly, especially some of the poorer, faster-growing sub-Saharan African nations whose evolution may be more interesting, from a demographer's point of view, than the "stagnated" populations of countries like Germany or Italy. As is well known from the statistics, the population of many sub-Saharan nations, as well as other nations like AlgeriaBangladeshEgypt and Pakistanwith their low family planningare growing much faster than in the aging European nations or Japan.

In general, although population growth in the former countries may slow in the future, it is unlikely that it will have stabilized byas predicted by the IDB data in some cases; they may also stay near the relatively high average level of 1.

Something similar can be said about Chinawhose population is still growing at an absolute rate of some 10 million per year, despite its government's efforts to stabilize it through its one child per couple policy. On the other hand, some other countries, like the small Asian state of Bhutanhave only recently had a thorough census for the first time: In Bhutan's case in particular, before its national population survey, [2] [3] [4] the IDB estimated its population at over 2 million; this was drastically reduced when the new census results were finally included in its database.

Besides, the IDB usually takes some time before including new data, as happened in the case of Indonesia. That country was reported by the IDB to have an inflated population of some million by mid, because it had not still processed the final results of the Indonesian census.

The largest absolute potential discrepancies are naturally related to the most populous nations. However, smaller states, such as Tuvalucan have large relative discrepancies. For instance, the census in that Oceanian island, which gave a final population of 9, [11] shows that IDB estimates can be significantly off. The national 1 July, mid-year population estimates usually based on past national censuses supplied in these tables are given in thousands. The retrospective figures use the present-day names and world political division: for example, the table gives data for each of the 15 republics of the former Soviet Unionas if they had already been independent in The opposite is the case for Germanywhich had been divided since the end of the Second World War but was reunified on October 3, To the right of each year column except for the initial onea percentage figure is shown, which gives the average annual growth for the previous five-year period.

Thus, the figures after the column show the percentage annual growth for the period; the figures after the column calculate the same value for —80; and so on. The formulas used for the annual growth rates are the standard ones, used both by the United Nations Statistics Division and by National Census Offices worldwide.

Population projections can vary drastically, even if they're working from the same population data. The UN Population Division projects that the world population will top out at around 11 billion, based on the average result of many different projections.

The far-reaching economic consequences of coronavirus will likely have some effect on growth rates, despite making a comparatively small impact on population sizes. Climate change is another variable that will have a drastic effect. Changes in the environment threaten important food production regions, like the Caribbean and the rainforests of Latin America e.

Brazil, which is the world's leading producer of soy and sugar cane. India, another major producer of global foods, is also at risk of instability due to climate change. Back in the s and s, when the population of the world reached its peak growth rate, there were many concerns about runaway population growth. Estimates of world population from recent years show that, while the total population is still growing, population growth has slowed considerably in the 21st century.

A large part of this reduction has been due to the drastic drop of fertility rates in developed countries, especially in Europe and Japan. Data suggest that as women get better access to birth control and are more able to participate in the workplace, the birth rate declines. Demographers also think that urbanization plays an important role in population change; children are more likely to work in agricultural societies, so there is more of an incentive to have more children.

There are some data that suggest a certain level of development can loop back around and cause an increase in the total fertility rate. As life expectancies increase and healthcare improves, many women might elect to have children later in life. In the United States, a Pew Research poll found that number of people with kids was higher than in This was attributable to a big bump in women having children between 34 and Most of the world's population increase is occurring in sub-Saharan Africa and southern Asia, especially in Nigeria and India.

The United States has a fertility rate comparable to other developed countries, but it has a rate of immigration that keeps its population well above replacement levels. China would have likely been the fastest growing, if not for the ongoing effects of their now abandoned one-child policy.

The United Nations forecasts the global population to reach 9. An aging population overall causes fertility to decline, as well as women in more developed countries not having the replacement rate of 2. If the fertility rate of a country is lower than the replacement rate, population declines there.

Predicting the 20 Most Populous Countries in 2050

Rosenberg, Matt. Predicting the 20 Most Populous Countries in Asia is the most populous continent, accounting for about two-thirds of the total population. The UN predicts the global population will surpass the 10 billion mark by Population growth rate varies by country and region. However, most countries and regions have positive population growth. But, the growth rate has declined significantly in some countries like China, due to government measures to reduce the ballooning population. The population growth rate is particularly high in Sub-Saharan Africa, with countries like Tanzania, Ethiopia, and the DRC expected to join Nigeria on the list of the top ten most populous countries by Five of the ten most populous countries are in Asia, three in the Americas, and one each in Europe and Africa.

With 1. It accounts for about India and China are the only two countries with a population of over one billion people. It is the 19th most-densely populated country, with about people per square kilometer. With a 1. About 90 million people in the US are immigrants and their US-born children. The UN estimates that the US, alongside eight other countries, will account for half of the global population by Indonesia has a population of Statistics show that the Indonesian population grew by about 1.

Brazil and Nigeria are the most populous countries in South America and Africa respectively. Nigeria is home to about The Nigerian population growth is driven by a high fertility rate and preference for large families. It is one of the countries in Europe that have experienced a mix of population growth and decline in the last three decades.
