Does anyone think that the world will have more than 9 billion in 2050?

The average number of children a woman gives to birth to worldwide is around 2.7 kids. We currently have 6.8 billion and will reach 7 billion around 2012, 13 years later than when our 6 billionth was reached. According to the U.N., they project we’ll have population of 9.2 billion by 2050 and then stable afterwards. The fertility rate in 2050 is projected to be around 2.05 kids per women. That’s a slow decline in the birth rate in over 40 years. We have young population worldwide, with more than half of the population under 25, they will soon get married and have children themseleves. Our population will keep rising quickly as the large young population has children and then their kids have children.
Until recently, the US had below replacement fertility for 35 years, we had more births than deaths during that all time. Even in the 1970s, when women were only giving birth to 1.7 kids on average, we still had 3 million births over 1.5 million deaths. And look at China, even though, most couples there are only allowed one child per, their population is still growing at a rate of 8 million yearly, China’s had a low birth rate for over 30 years and their population is still rising rapidly.
So I think the world will keep growing after 2050 and I think the world will have around 11 billion people in 2050 and 14 billion in 2100, with rises in life expectancy, not as many people will be dying so much.
