The world population is growing at an unprecedented rate. It will nearly double as much as we have today by 2100.
Currently, the world population is 7.3 billion. It will be 9.7 million in 2050 and will cross 11 billion by the end of the century, according to United Nations Population Division.
The global population growth will be largely driven by Africa. The continent’s current population is 1.2 billion. It is expected to triple or quadruple over the next 85 years. This is all due to consistent rapid growth in population in the region. Nigeria will likely be the biggest contributor if it continues to follow the current trend.
United States will also have a significant increase in population. The country is projected to add an average 1.5 million people each year, which will push the current count of 322 million people to 450 million.
According to global projections, Asia which is the most populous continent right now will remain most populous continent in future as well. Asia’s current population is 4.4 billion. It is expected to exceed 5.3 billion till the mid of the century but will decline to 4.9 billion by the end of the century.
The report also examined the Potential Support Ratio (PSR) of different countries. It is way to determine the aging population in a country. It tells the number of working-age people (20 to 64) per one elderly person aged 65 or over. The more elderly population grows, the more PSR falls. Meaning there are fewer people to support elderly people. Japan has the lowest PSR with 2.1. United States’s PSR is projected to decline from 4.0 to 1.9 till 2100. Germany, China, Mexico and Bangladesh will also face a sharp decline by the end of the century.
These estimations, presented at 2015 Joint Statistical Meetings Monday, also indicate how important it is to take measurements for controlling rapid population growth. It has an impact on government policies like high fertility countries face many problems including health, environmental and economical. According to John R. Wilmoth the director of UN Population Division, the world population growth will not end until fertility level declines.

I’m betting on Malthus, not the UN prediction.

There are two positive aspects: the number of children per woman is closing in steadily on the stable reproduction rate of 2,1 children per woman. Much of the future population growth is due to already born children who enter their reproductive age in the decades to come. Another factor is higher life expectance. So there’s a trend towards conscience and maturity (maybe it’s just stress caused by overpopulation, though). Population growth just won’t level off from one day to another. Do ten or even twelve billion people surpass the world’s carrying capacity? With the actual model of middle class well being spreading across the globe probably the answer is yes. But who on this forum is willing to give up his standard of living to save the world?

Almost all of the projected population growth is going to happen in Africa. The study predicts Africa’s current population will triple or quadruple by 2100. The Bill and Melinda Gates Foundation is doing excellent work by funding contraception and family planning in Africa, but much more should be done there.

I wonder what data they take into consideration when coming up with these estimates?
If “The System” is still running BAU come 2050, can you even imagine how far automation will have advanced? What jobs will be available for the eligible workforce within that 9.7 billion figure?
And then what if there’s any substance to this climate change thingy we’ve all been hearing about. 35 more years should be enough time to see if we’ve made an oopsy of our biosphere.

Humans have exceeded the carrying capacity of their planet to the point where this discussion is moot, unless one wants to discuss how outrageous these predictions are.

Back in 2000 I had a roughly 1000 acre corn and soybean farm. Here is where it was located: http://www.airphotona.com/image.asp?imageid=4022. I did that for 4 years. It was the toughest work I ever did. I remember all that went into that work. I just can’t imagine more people on this earth if our economy shrinks and or agricultural inputs shrink. It appears both of these scenarios are in motion.
I am now involved with permaculture cattle and goats. I have a garden. I will have chickens soon. If I had to do all this with less resources I don’t know if it would work. There is the part of me that opines doom in the abstract. There is another part of me that reflects on my experience growing food and thinks WTF do we think we are doing happy facing the idea of more people on this earth.
It feels absurd to read this articles knowing what I know about producing food, peak oil dynamics, the global economic system, and ecological decline. WTF, I had to say that one more time because this is just bizarre talk out of a bunch of crazy humans entertaining the idea of more people on this overpopulated earth.
This is what I am buying into more than anything I am reading in the news: http://www.paulchefurka.ca/Population.html. I am not convinced peak oil will be our downfall. Its dynamics will of course be part of it. Currently I see our economy shrinking leading to the population rebalance as the near term driver of population rebalance. All it will take is less growth and something will give.
This global system bifurcation is crystal clear in my mind but I realize there is more to reality than linear thought. I am disgusted with the idea of more people destroying the world even though they have as much right to life as I do. I have to say this period in history sucks because bottlenecks surely suck. We are definitely in overshoot so I know that feeling. I can’t imagine a bottleneck. What is so scary is we are close to one.

Don’t worry Davy, you have to think of the opportunity a collapsing society will herald.
After you’ve prepped, consider your entertainment.

Oh, and there will be plenty of entertainment.

Not a chance that this forecast will unfold as predicted. The world cannot support much more of anything, let alone increased consumption.
Who would want to live in a world with twice the population? Look at economic and climate induced migration now. Can you imagine even more stressors on societies?

“World Population Will Nearly Double by 2100”
What will double? The population of rats? Roaches? Flies? There will be a lot of dead human bodies that remain unburied, I think. But 2100 will see only wandering tribes of hunter gatherers, if any humans survive the next 85 years. I don’t see any signs of another future for humanity.

Schramski JR, Gattie DK, Brown JH, “Human domination of the biosphere: rapid discharge of the earth-space battery foretells the future of humankind”. Proceedings of the National Academy of Sciences.
This tells the story. Our advances have permitted our human population to mushroom while decimating the plant and animal kingdom. The price that we will pay is the likely return to equilibrium between earth and outer space probably within the next 1000 years unless we make radical changes and consume much less energy.

Better get some 1,000,000,000 passenger interstellar spaceships built quick, I reckon. Otherwise, we may have ourselves a little overshoot problem.

“I don’t see any signs of another future for humanity.”
Not with how we’re destroying the Earth’s Biosphere. Eventually all those species we drove to extinction because we thought they were pests or they didn’t matter will come back to bite humanity in the ass.

“It will nearly double as much as we have today by 2100.” Sure…no problamo. Based upon the recent rate of increase in global oil production we will be producing more then 300 million bopd by then also. Thus the population will be taken care of. It’s just a simple extrapolation of a rate at a point in time.

Barring any new discoveries in the nature of reality and the breaking of the laws of entropy, then by the end of this century we’ll probably have about half what we have now possibly even less.
If population does double then by the end of next century we’ll have 0 people left. I know which I’d rather

no point engaging the brakes now, we already went over the edge.

There will certainly be starvation in the Third World, and harsh times in the Second World after the age of oil really starts winding down, but I don’t see bodies laying unburied in First World areas. Anyway, all of that is decades in the future. Things have to get a lot worse for everyone first, and that sort of change doesn’t happen overnight. Let’s not forget that even after a 30% reduction in oil production, we’re still at 1970s levels, and back in the 1970s we were not exactly back in the dark ages. Even when we take into account the extra population since that time that need energy, we aren’t going to be in dreadful trouble. Sure, things are going to be tough, but it’s not the fricken zombie apocalypse that some here seem to be predicting.
Makati1 on Thu, 13th Aug 2015 8:58 am
Beery? All of the millions of bodies will be buried by whom? The hospitals are already crowded because there are not enough beds to go around. When the SHTF, there could be thousands of deaths EVERY DAY in each city of the 1st world. Who is going to bury them and where? If you are ‘on the farm’ and there is another person, you may get buried, or maybe not if they are not able. Or if flu or another disease takes all of you at the same time. Then the rats, flies and other vermin will take care of your remains.
For instance:
“…Thousands died – an estimated 11,000 in November increasing to 53,000 in December. The frozen earth meant their bodies could not be buried. Corpses accumulated in the city’s streets, parks and other open areas … You don’t know what it was like. You just stepped over corpses in the street and on the stairs. You simply stopped taking any. It was no use worrying … There were so many people dying all over the place authorities couldn’t keep track of all the deaths ….”
http://www.eyewitnesstohistory.com/leningrad.htm
And this was a small city (~3 million), by today’s standards, but this is the effects of starvation and lack of energy sources. THIS is our future, even in the 1st world and maybe even more so there than in the 3rd world. Read it if you want a good picture of our future. Dream all you want, but when the system crashes, it will not start up again.
Makati1 on Thu, 13th Aug 2015 8:59 am
Beery, you ain’t seen “tough” like you are going to see in the near future.
penury on Thu, 13th Aug 2015 11:23 am
So with ‘fusion”reactors in five years or less, the energy issue is solved. With new farming (perma culture) the food situation will be taken care of. Global warming will ensure that people will no longer need heating for their domiciles. Whee, go forth and multiply all will be awesome.
BC on Thu, 13th Aug 2015 11:27 am
Plant is correct about the vast majority of population growth occurring in Africa, but that just means the Dark Continent will be even darker in terms of resource depletion, ecological destruction, conflict, violence, failed attempts at out-migration, warlordism, etc.
IOW, in addition to India, sub-Saharan Africa will become the definition of Hell on Earth.
But that won’t stop the neo-imperial “race for Africa” (as a “frontier market”) by the West and China as part of the last-man-standing contest for the remaining finite resources on Spaceship Earth.
Bob Owens on Thu, 13th Aug 2015 11:45 am
This author is trying to project 85 years into the future. Any projection more than 5 years into the future is suspect. Heck, we can’t even project the price of gas 1 week into the future and get it right! The world is spinning out of control so fast we won’t even recognize our world in 10 years (I project), let alone 85!

Milret2 on Thu, 13th Aug 2015 2:10 pm
Since this is the internet all predictions are extra suspect including mine but what the heck … I am gonna make one any way based on recent heat waves, loss of earth’s air conditioning, how that will affect both live stock and plant growth, human nature, the overage of nuclear weapons on earth, and the number of fanatics on this planet. My prediction is that within ten years we will see the human population drop like it has never dropped before and I am aware of previous bottlenecks;-).
apneaman on Thu, 13th Aug 2015 2:22 pm
Milret2, I agree. I think you might be interested in what, John Hawks, professor of Anthropology at the University of Wisconsin–Madison has to say about the research on previous bottlenecks. Here is a site search on bottle necks articles from his site, which has many very cool articles – if your into ape history.

Africa could feed the whole world and have room for the wild animals, but their agricultural technology is still amazingly primitive. Just getting them up to European medieval levels would be huge progress. But it’s more likely that it will just turn into a huge version of Haiti. The fact that they have oil reserves is probably the kiss of death, because the west will prop up corrupt puppet regimes that prevent reform.
Apneaman on Thu, 13th Aug 2015 5:48 pm
It’s just amazing that with the entirety of scientific research and data at their finger tips, the apes at the UN are still promoting and projecting a growth based worldview. These people actually have more access to information and even to the scientists themselves then anyone of us has. They must be under a lot of pressure to maintain the illusion or they are deep in a collective, group think, delusion.

People that can least afford to provide for their children have the most children leaving it to society to care for them.

Kenz300 on Mon, 17th Aug 2015 7:07 am
Having a child and then watching them starve to death because you can not provide for them is just cruel.
If you can not provide for yourself you can not provide for a child.
Don’t have more children than you can provide food, shelter, clothing, love, a good eduction and a job for…………. to do anything else just breeds more poverty, suffering and despair.
