ArmInfo.According to a UN demographic report by 2050, the population of Armenia will decrease to an average of 2 million 816 thousand people,. According to the pessimistic version of the UN forecast, the population of Armenia will drop to 1 million 207 thousand people by the end of the century (a decline of 1 million 745 thousand people), according to an optimistic forecast, it will amount to 3 million 175 thousand people (an increase of 224 thousand people). The report also notes that the population of Armenia in 2018 increased by 7 thousand people, thus reaching 2 million 952 thousand people.
According to UN estimates, in Armenia it is forecasted population growth of 6 thousand people in the period from 2019 to 2020. According to the latest UN estimates, as of June 17, 2019, the population of Armenia is 2,936,607 people. The population of Armenia is 0.04% of the total population of the world. By 2050, about 9.7 billion people will live on Earth, the UN report says, but overall, growth will continue to decline, and countries will have to adapt to the effects of an aging population. It is expected that India will demonstrate the highest population growth in the period up to 2050, overtaking China as the most populous country in the world by about 2027, the report said. The largest growth is expected in nine countries: India, Nigeria and Pakistan, followed by the Democratic Republic of Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States of America. Overall, it is expected that by 2050 the population of sub-Saharan Africa will double. However, growth in these countries is occurring against the background of a slowdown in the global birth rate. In 1990, the average number of births per woman was 3.2. By 2019, this figure dropped to 2.5 births per woman, and by 2050, it is projected to drop to 2.2 births: a birth rate of 2.1 births per woman is needed in order to avoid a decrease in population countries in the long run (in the absence of immigration).
The population of an increasing number of countries is actually declining. Since 2010, there has been a decrease of at least one percent in 27 countries or areas due to the continuing low birth rate. It is expected that in the period up to 2050 this figure will increase to 55 countries whose population will decrease by one percent or more, and in almost half of them this reduction will be at least 10 percent. In some cases, population decline is aggravated by high rates of emigration, and migration flows have become the main cause of population change in some regions. Bangladesh, Nepal and the Philippines are facing the largest migration outflow due to the demand for migrant workers; and Myanmar, Syria and Venezuela are the countries from which the largest number leave because of violence, insecurity or armed conflict. In countries where the population is declining, immigration is expected to fill gaps, especially in Belarus, Estonia and Germany. "Many of the fastest-growing populations are in the poorest countries, where population growth creates additional problems," said Under-Secretary-General for Economic and Social Affairs Liu Zhenmin.
These tasks include the fight to eradicate poverty and combat hunger and malnutrition, promote greater equality, improve health and education. At the same time, economic growth offers opportunities for many developing countries: recent fertility reductions mean that the working-age population (from 25 to 64 years old) is growing faster than in other age groups, which can improve opportunities to accelerate economic growth. The report recommends using this for investment in health education. By 2050, every sixth person will be over 65, compared with the current figure of 11. In some regions, the proportion of older people will double in the next 30 years, including North Africa, Asia and Latin America. By 2050, a quarter of the population of Europe and North America may be over 65 years old. A higher proportion and a greater number of older people are expected to exert greater financial pressure on countries over the coming decades due to higher spending on health care systems, pensions and social protection. Although the overall life expectancy will increase (from 64.2 years in 1990 to 77.1 years in 2050), life expectancy in poorer countries will still lag behind. Today, the average life expectancy of a child born in one of the least developed countries will be about 7 years shorter than someone born in a developed country. The main causes are high infant and maternal mortality rates, violence and the continuing impact of the HIV / AIDS epidemic. The current estimate of the world population of the United States Census Bureau in June 2019 shows that there are approximately 7,577,13400 people on Earth, which is much higher than the population of 7.2 billion people since 2015. China is the most populous country in the world with a population of over 1.4 billion. It is one of two countries with a population of over 1 billion people, and India is the second. As of 2018, India's population is more than 1.355 billion people, and its growth is expected to continue at least until 2050. By 2030, India is expected to become the most populous country in the world. This is because the population of India will grow, while China is projected to face a loss of population. In the next 11 countries that are the most densely populated in the world, the population exceeds 100 million people. These include the United States, Indonesia, Brazil, Pakistan, Nigeria, Bangladesh, Russia, Mexico, Japan, Ethiopia, and the Philippines.
It is expected that all of these countries will continue to grow, with the exception of Russia and Japan, whose population will shrink by 2030 before being significantly reduced again by 2050. In 2018, the world's population grew by 1.12%. Every five years, since 1970, the growth rate continued to fall. It is expected that the world's population will continue to grow, but at a much slower pace. By 2030, the population will exceed 8 billion. In 2040, this figure will rise to 9 billion. In 2055 their number will increase to 10 billion, and the end of the century will not exceed 11 billion. The United Nations estimates that the annual population growth is now estimated at millions - an estimated more than 80 million new lives are added each year.
