The current population of World in 2023 is 8,045,311,447, a 0.88% increase from 2022. The population of World in 2022 was 7,975,105,156, a 0.83% increase from 2021. The population of World in 2021 was 7,909,295,151, a 0.87% increase from 2020.
The projected world population on Jan. 1, 2023, is 7,942,645,086, an increase of 73,772,634, or 0.94%, from New Year's Day 2022.
The current world population of 7.6 billion is expected to reach 8.6 billion in 2030, 9.8 billion in 2050 and 11.2 billion in 2100, according to a new United Nations report being launched today.
Gender ratio in the World
As of 2021, There are 3,970,238,390 or 3,970 million or 3.97 billion males in the world, representing 50.42% of the world population.
Research over hundreds of years has consistently found that boys naturally outnumber girls at birth. The speculation is that this is nature's way of countering the relatively high mortality rates of males, and creating more of a gender balance in the population.
The world in 2100 will be hotter, with more extreme weather and more natural disasters such as hurricanes and wildfires. How much hotter? It is impossible to know right now, as it will depend on our actions during the next 80 years. There are different scenarios, from the world being 1.5ºC to 5ºC hotter by 2100.
But how long can humans last? Eventually humans will go extinct. At the most wildly optimistic estimate, our species will last perhaps another billion years but end when the expanding envelope of the sun swells outward and heats the planet to a Venus-like state. But a billion years is a long time.
The world's population in 2015 stands at 7.3 billion people and it is projected to increase to 8.5 billion in 2030.
Earth's capacity
Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people.
We are approximately nearing the year 2023, and as of the current day, there are 170 days left until 2023.
While it took the global population 12 years to grow from 7 to 8 billion, it will take approximately 15 years—until 2037— for it to reach 9 billion, a sign that the overall growth rate of the global population is slowing.
Extending the UN's probabilistic population models, the paper, published in the International Journal of Forecasting, found that our population size in 2300 will likely be between 2 and 26 billion people, with a median projection of 7.5 billion.
Humans in the year 3000 will have a larger skull but, at the same time, a very small brain. "It's possible that we will develop thicker skulls, but if a scientific theory is to be believed, technology can also change the size of our brains," they write.
In the next 1,000 years, the amount of languages spoken on the planet are set to seriously diminish, and all that extra heat and UV radiation could see darker skin become an evolutionary advantage. And we're all set to get a whole lot taller and thinner, if we want to survive, that is.
New genetic findings suggest that early humans living about one million years ago were extremely close to extinction. The genetic evidence suggests that the effective population—an indicator of genetic diversity—of early human species back then, including Homo erectus, H.
2100: Either uninhabitable or beginning to repair
Over the coming two decades, extreme weather is set to disrupt society with increasingly severe bushfires, drought and storms. The good news is by the end of the century, living on Earth could actually be more pleasant than it is today.
By 2100, the projected warming is between 1.2°C and 4.1°C, similar to the range projected by AOGCMs. A large constant composition temperature and sea level commitment is evident in the simulations and is slowly realised over coming centuries. By the year 3000, the warming range is 1.9°C to 5.6°C.
Based on known risks, the really cataclysmic ones, those that might exterminate us as a species, are fairly rare. Based on what we know today, it would be very unlikely that we wouldn't be around in the year 3000. There certainly would be bad times, but some of us would get through it. That leaves unknown risks.
When we look at the statistics the chances of having a boy or a girl are almost the same and there's no medical evidence to suggest we can influence this. You may, however, have heard about the 'Shettles Method'.
Among humans, women's life span is almost 8% on average longer than men's life span. But among wild mammals, females in 60% of the studied species have, on average, 18.6% longer lifespans.
