The HOB – Closing Spring 2019
– Reflection,… a World await!
Right now, the world’s population is over 7.7 billion people, and it has been growing between 1% and 2% every year since 1950, according to the Pew Research Center. By 2100, the center projects the population will reach around 10.9 billion people and grow by less than 0.1% a year, the center wrote. continue here …
Population Science and Fiction
In 1798 the UK economist Thomas R Malthus (1766-1834) published his Essay on the Principle of Population as it Affects the Future Improvement of Society, arguing that a Utopian situation of peace and plenty would be impossible to achieve because the tendency of populations, in the absence of the checks of war, famine and plague, to increase exponentially would result in society’s continually outgrowing its resources. In the second edition of 1803, replying to criticism, he introduced another hypothetical check: voluntary restriction of population by the exercise of “moral restraint”. But Malthus had little faith in the effectiveness of moral restraint, and most modern sf writers agree with him…more here …
World Population in 2050
What will the world look like in 2050? The world’s population 30 years from now may look more different than we expect. According to World Population Prospects, the global population in 2050 will be around 9.77 billion people, which is 2 billion more than what the current population is today.
In terms of each country’s population growth, we can expect India to surpass China as the most populated country in the world by 2050. Today, India’s growth rate is 1.08% while China, the most populated country in the world at the moment, has a growth rate of only 0.35%. By 2050, India’s population will hit 1.66 billion people, and China will come in second place with a population of 1.36 billion.
The United States currently is the third most populated country in the world, but is expected to drop to fourth most populated by 2050. Instead, fast-growing Nigeria will become the third most populated country by 2050 with its current growth rate of 2.6%. Nigeria’s population will be around 410 million by 2050 while the US in 2050 will have about 390 million people.
Vatican City is predicted to continue being the least populated country in the world in 2050. It currently has a negative growth rate and is predicted to have 800 people by 2050.
Trends are pointing towards the most populated countries reaching their capacities and slowing down their population growths. Meanwhile, less populated countries with developing industries and technologies will see a boom in population growth, which are similar factors that allowed the recent growth of India and China in the last century…continue here …
UNDESA – World Population Prospects 2019
Globally, the level of fertility is expected to fall from an average of 2.5 live births per woman in 2019 to 2.2 in 2050 and to 1.9 in 2100, according to the medium-variant projection. However, in Europe and Northern America, total fertility is projected to increase slightly by the end of the century from 1.7 in 2019 to 1.8 in 2100…… all here
World Population Milestone
10 Billion (2055)
The United Nations projects world population to reach 10 billion in the year 2056.
8 Billion (2023)
World population is expected to reach 8 billion people in 2023 according to the United Nations (in 2026 according to the U.S. Census Bureau).
7.7 Billion (2019)
The current world population is 7.7 billion as of June 2019  according to the most recent United Nations estimates elaborated by Worldometers. The term “World Population” refers to the human population (the total number of humans currently living) of the world.
7 Billion (2011)
According to the United Nations, world population reached 7 Billion on October 31, 2011.
The US Census Bureau made a lower estimate, for which the 7 billion mark was only reached on March 12, 2012.
6 Billion (1999)
According to the United Nations, the 6 billion figure was reached on October 12, 1999 (celebrated as the Day of 6 Billion). According to the U.S. Census Bureau instead, the six billion milestone was reached on July 22, 1999, at about 3:49 AM GMT. Yet, according to the U.S. Census, the date and time of when 6 billion was reached will probably change because the already uncertain estimates are constantly being updated… continue here …
… in Life We Trust!
In biology or human geography, population growth is the increase in the number of individuals in a population. Many of the world’s countries, including many in Sub-Saharan Africa, the Middle East, South Asia and South East Asia, have seen a sharp rise in population since the end of the Cold War. The fear is that high population numbers are putting further strain on natural resources, food supplies, fuel supplies, employment, housing, etc. in some of the less fortunate countries. For example, the population of Chad has ultimately grown from 6,279,921 in 1993 to 10,329,208 in 2009,further straining its resources. Niger, Pakistan, Nigeria, Egypt, Ethiopia, and the DRC are witnessing a similar growth in population.
Global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.616 billion in 2018. It is expected to keep growing, and estimates have put the total population at 8.6 billion by mid-2030, 9.8 billion by mid-2050 and 11.2 billion by 2100... here …
Two hundred years ago the world population was just over one billion. Since then the number of people on the planet grew more than 7-fold to 7.7 billion in 2019. How is the world population distributed across regions and how did it change over this period of rapid global growth?
In the visualization below we see historical population estimates by region from 1820 through to today. These estimates are published by the History Database of the Global Environment (HYDE) and the United Nations Population Division from 1950 onwards.
Most people always lived in Asia: Today it is 60% two hundred years ago it was 68%. If you want to see the relative distribution across the world regions in more detail you can switch to the relative view.
The world region that saw the fastest population growth over last two centuries was North America. The population grew 31-fold. Latin America saw the second largest increase (28-fold). Over the same period the population Europe of increased 3-fold, in Africa 14-fold, and in Asia 6-fold… continue here …
a real life ‘scifi’ scenario, Earth 2050
By 2050, a quarter of the population in European and Northern America could be 65 or over. The higher proportion and number of 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 64.2 years in 1990 to 77.1 years in 2050), life expectancy in poorer countries will continue to lag behind. Today, the average lifespan of a baby born in one of the least developed countries will 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…. continue here …
