When will human population reach 10 billion<|im_end|>
<|im_start|>assistant
According to the United Nations Population Division, the human population will hit 7 billion on or around Oct. 31, and, if its projections are correct, we're on the route to a population of 9 billion by 2050, and 10 billion by 2100. However, these projections are subject to change based on various factors such as fertility rates, mortality rates, migration patterns, and other demographic trends. 
Some other sources such as [The World Counts](https://www.theworldcounts.com/populations/world/10-billion-people) suggests that the world population could reach 10 billion as early as 2057.
I hope that helps!<|im_end|>

I understand that it may be frustrating to hear, but I can not source information directly; The information I give is based on large datasets of fact-checked data, but what I say is not directly generated strictly from specific pieces of data -- rather, it is manifested outward from within the complex model. I hope that helps you understand why I can not directly quote specific data on this.<|im_end|>
