What would be the world population if the World Wars never happened?

Answer 1

If we say that, on average, each person that was killed had 2 children, the planets population would rise from 6,903,500,000 to 7,312,500,000!! That is an increase of 409,000,000 people and that does not include the children's possible children.

Answer 2

6,909,318,762 is the current population from the US Census Bureau

Now consider this: 50 - 70 million people were killed. Lets take the higher number.

If three people were born to each one of those people (and trust me it would have been a lot more).

So you would multiply 3 X 70,000,000 and get 210,000,000. So that many more people would be added to the world's total population number of today.
