The day when the world population reaches 7 billion is only 12 years away from the "6 billion population day". 1999, Adnan Mevic, born in Bosnia and Herzegovina, was designated as the "6 billionth person", and the commemorative ceremony held for this was still vivid.

According to the statistics of the United Nations Population Fund, it took more than a century for the world population to grow from 10 billion to 2 billion, and it took 32 years for it to grow from 2 billion to 3 billion. Since 1987, it has increased every 12 years.

Of the 7 billion people in the world,1800 million are young people aged 10 to 24. It is predicted that if the current fertility rate remains unchanged, the world population will soon exceed 9 billion in the middle of this century, and then the population growth rate will slow down and exceed10 billion by the end of this century. When releasing the population report of 20 1 1 year, Osotimehin, executive director of the United Nations Population Fund, believed that the population of 7 billion was "both a challenge and an opportunity". Where does the opportunity exist?

In fact, the population problem also has two sides. On the one hand, the appropriate, school-age and high-quality labor force is an important driving force for development, which is called "demographic dividend", but too large a labor force will also bring employment difficulties; On the other hand, the aging population, low cultural quality and unbalanced sex ratio will bring complex social problems.

Osotimehin believes that 90% of the1800 million young people in the global population of 7 billion live in developing countries. If developing China countries can increase investment in education, health and other fields and improve their ability, it will bring huge "demographic dividend" for future development.
