It took 12 years for the population to increase by a billion people.
On November 15, according to UN estimates, the population our planet has reached the mark of eight billion people. The organization attributes this to a gradual increase in life expectancy due to improvements in health care, nutrition, personal hygiene and medicine, as well as high birth rates in some countries.
It is noted that the population of our planet took 12 years to grow from seven to eight billion. But, according to forecasts, it will take 15 years to reach the nine billion mark, which indicates a slowdown in population growth.

The UN also noted that countries with the highest birth rates usually have the lowest per capita income. That is, global population growth over time is increasingly concentrated in the world's poorest countries, most of which are in sub-Saharan Africa. At the same time, such growth is not observed in high-income countries.
According to the organization, the population is currently growing at the slowest rate since the 1950s. The latest UN projections suggest that the world population could grow to around 8.5 billion in 2030 and 9.7 billion in 2050, peaking at 10.4 billion people in the 2080s and remaining at that level until 2100 year.
