The world’s population has reached 7.8 billion, the German Foundation for World Population (DSW) reported ahead of World Population Day.

The fund said the population of our planet is increasing by 82 million people annually. An average of 2.6 babies are born every second all over the world.

DSW experts said that the reason for the continued population growth is a large number of unwanted pregnancies. Globally, two out of every five pregnancies are undesirable.

Experts say that sex education and the use of contraceptives could change the situation, DW reported.

According to DSW, the situation in the Sub-Saharan African region is the most complex as every second woman of this region is denied access to contraceptives. Despite the decline in the birth rate in this region, there are still 4.4 children per woman here - an average of 2.4 children worldwide. As a result, the number of inhabitants of this region, according to UN forecasts, will increase from 1.3 billion to 2.5 billion people by 2050.
