Question

According to speculation and study, what will happen to the global birth rate in about 40 years?

Answer 1

Birth rates also vary in a geographic area among demographic groups. Some increases and some decreases. In 2012 the average global birth rate was 19.15 births per 1,000 total population, compared to 20.09 per 1,000 total population in 2007. Again, the average global birth rate has shrunk to 18.6 births per 1,000 total population in 2016. There is a possiblity is will decrease 

Answer 2

The correct answer is - Birth rate will decrease.

In the past few decades, the birthrate, on a global scale, is decreasing. This doesn't mean that the population is shrinking though, on contrary, it is growing, but the tempo of growing is slowing down. Also, there's variations from one region to another, and while most of the world is experiencing significantly lower birthrates than few decades ago, Africa still has a very high one, with only very slightly reduction of it. Still, according to the prognosis for the next decades, the birthrate, on a global scale will continue to lower down little by little.
