November 15 has practically arrived and according to the United Nations report the world population will reach eight billion. India is the country that will overtake China as the most populous country on earth in 2023. Achieving this figure “is a reminder of our shared responsibility to care for our planet and a time to reflect on where we still fail to comply. our mutual commitments “, said Secretary General Antonio Guterres.

The forecast from the United Nations Department of Economic and Social Affairs states that the world’s population is growing at the slowest pace since 1950.

It is expected to reach 8.5 billion in 2030 and 9.7 billion in 2050, peaking around 10.4 billion people in the 1980s before stabilizing at that level until 2100.

While a sharp decline in birth rates is observed in several developing countries, more than half of the projected increase in the world’s population in the coming decades will be concentrated in eight countries, the report says: the Democratic Republic of the Congo, Egypt. , Ethiopia, India, Nigeria, Pakistan, the Philippines and Tanzania.

The UN report recalls that it took hundreds of thousands of years for the world’s population to grow to 1 billion, then in just another 200 years or so, it grew sevenfold. This growth has been driven in large part by the high number of people surviving the reproductive age and has been accompanied by major changes in fertility rates, increased urbanization and accelerated migration. “These trends will have far-reaching implications for generations to come,” the UN stresses. The recent past has seen huge changes in fertility rates and life expectancy. In the early 1970s, women had an average of 4.5 children each; in 2015, total fertility worldwide had dropped to below 2.5 children per woman. Meanwhile, the global average lifespan has increased, from 64.6 years in the early 1990s to 72.6 years in 2019.

In addition, there are high levels of urbanization and an acceleration of migration around the world. 2007 was the first year that more people lived in urban areas than in rural areas, and by 2050 around 66% of the world’s population will live in cities. These mega trends have far-reaching implications. They affect economic development, employment, income distribution, poverty and social protection.

They also impact efforts to ensure universal access to health care, education, housing, sanitation, water, food and energy. “To address the needs of individuals in a more sustainable way – concludes the UN – policy makers must understand how many people live on the planet, where they are, how old they are and how many people will come after them”.
