By the yearthere will be some 9. However, the overall growth rate will continue to fall, and more countries will have to adapt to the consequences of an ageing population. India, along with eight other countries, will make up over half how to boot from cd the estimated population growth between now and In all, the population of sub-Saharan Africa is expected to practically double by However, growth in these countries comes against the backdrop of a slowing global fertility rate.
Inthe average number of births per woman was 3. By this had fallen to 2. The population size of more and more countries is actually falling.
Since27 countries or areas have seen a drop of at least one per cent, because of persistently low fertility rates. Between now andthat is expected to expand to 55 countries which will see a population decrease of one per cent or more, and almost half of these will experience a drop of at least 10 per cent. In some cases, the falling population size is reinforced by high rates of emigration, and migration flows have become a major reason for population change in certain regions.
Bangladesh, Nepal and the Philippines are seeing the largest migratory outflows resulting from the demand for migrant workers; and Myanmar, Syria and Venezuela are the countries where the largest numbers are leaving because of violence, insecurity or armed conflict.
For those countries where population is falling, immigration is expected to plug the gaps, particularly in Belarus, Estonia and Germany. These challenges include the fight to eradicate poverty, and combat hunger and malnutrition; greater equality; and improved healthcare and education. At the same time, growth is providing opportunities in many developing economies: recent reductions in fertility mean that the working-age population 25 to 64 is growing faster than other age ranges, which could improve the possibilities for faster economic growth.
There will be one in six people over 65 byup from the current figure of one in Some regions will see the share of older people double in the next 30 years, including Northern Africa, Asia and Latin America. Bya quarter of the population in European and Northern America could be 65 or over. The higher proportion and number what is the projected world population in 2050 older people is expected to put increased financial pressure on countries in the coming decades, with the higher cost of public health, pensions and social protections systems.
Although overall life expectancy will increase from Today, the average lifespan of a baby born in one of the least developed countries how to make bling effect in photoshop be some 7 years shorter than one born in a developed country.
The main reasons are high child and maternal mortality rates, violence, and the continuing impact of the HIV epidemic. The report is based on population estimates what is the projected world population in 2050 to the present for countries or areas, underpinned by analyses of historical demographic trends.
The revision also includes population projections to the yearthat reflect a range of plausible outcomes at the global, regional and country levels.

The World Population Prospects 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 new population projections indicate that nine countries will make up more than half the projected growth of the global population between now and India, Nigeria, Pakistan, the Democratic Republic of the Congo, Ethiopia, the United Republic of Tanzania, Indonesia, Egypt and the United States of America in descending order of the expected increase.
The global fertility rate, which fell from 3. In , fertility remains above 2. A fertility level of 2. Liu Zhenmin, United Nations Under-Secretary-General for Economic and Social Affairs, said the report offers a roadmap indicating where to target action and interventions.
Growth of the working-age population is creating opportunities for economic growth. In most of sub-Saharan Africa, and in parts of Asia and Latin America and the Caribbean, recent reductions in fertility have caused the population at working ages years to grow faster than at other ages, creating an opportunity for accelerated economic growth thanks to a favourable population age distribution. People in the poorest countries still live 7 years less than the global average.
Life expectancy at birth for the world, which increased from While considerable progress has been made in closing the longevity differential between countries, large gaps remain. In , life expectancy at birth in the least developed countries lags 7. By , one in four persons living in Europe and Northern America could be aged 65 or over. In , for the first time in history, persons aged 65 or above outnumbered children under five years of age globally.
The number of persons aged 80 years or over is projected to triple, from million in to million in Falling proportion of working-age population is putting pressure on social protection systems. The potential support ratio, which compares numbers of persons at working ages to those over age 65, is falling around the world. In Japan this ratio is 1. An additional 29 countries, mostly in Europe and the Caribbean, already have potential support ratios below three.
By , 48 countries, mostly in Europe, Northern America, and Eastern and South-Eastern Asia, are expected to have potential support ratios below two. These low values underscore the potential impact of population ageing on the labour market and economic performance, as well as the fiscal pressures that many countries will face in the coming decades as they seek to build and maintain public systems of health care, pensions and social protection for older persons.
Since , 27 countries or areas have experienced a reduction of one per cent or more in the size of their populations. This drop is caused by sustained low levels of fertility. The impact of low fertility on population size is reinforced in some locations by high rates of emigration.
Between and , populations are projected to decrease by one per cent or more in 55 countries or areas, of which 26 may see a reduction of at least ten per cent. In China, for example, the population is projected to decrease by Between and , fourteen countries or areas will see a net inflow of more than one million migrants, while ten countries will see a net outflow of similar magnitude.

Belarus, Estonia, Germany, Hungary, Italy, Japan, the Russian Federation, Serbia and Ukraine will experience a net inflow of migrants over the decade, helping to offset population losses caused by an excess of deaths over births.
The report includes updated population estimates from to the present for 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, national population censuses conducted between and , as well as information from vital registration systems and from 2, nationally representative sample surveys.
