A world of 8
billion: Towards a resilient future for all - Harnessing opportunities and ensuring
rights and choices for all
🧑🌾🧑🎓👩🍳🧑🎨💂♂️
Reaching a global population of eight billion is a
numerical landmark, but our focus must always be on people. In the world we
strive to build, 8 billion people means 8 billion opportunities to live
dignified and fulfilled lives.

◈World Population Trends
It took hundreds of thousands of years for the
world population to grow to 1 billion – then in just another 200 years or so,
it grew sevenfold. In 2011, the global population reached the 7 billion mark,
it stands at almost 7.9 billion in 2021, and it's expected to grow to around
8.5 billion in 2030, 9.7 billion in 2050, and 10.9 billion in 2100.
This dramatic growth has been driven largely by
increasing numbers of people surviving to reproductive age, and has been
accompanied by major changes in fertility rates, increasing urbanization and
accelerating migration. These trends will have far-reaching implications for
generations to come.
The recent past has seen enormous changes in fertility rates and life expectancy. In the early 1970s, women had on average 4.5 children each; by 2015, total
fertility for the world had fallen to below 2.5 children per woman. Meanwhile,
average global lifespans have risen, from 64.6 years in the early
1990s to 72.6 years in 2019.
In addition, the world is seeing high levels
of urbanization and
accelerating migration. 2007 was the first year in which more people lived
in urban areas than
in rural areas, and by 2050 about 66 per cent of the world
population will be living in cities.
These megatrends have far-reaching implications.
They affect economic development, employment, income distribution, poverty and
social protections. They also affect efforts to ensure universal access to
health care, education, housing, sanitation, water, food and energy. To more
sustainably address the needs of individuals, policymakers must understand how
many people are living on the planet, where they are, how old they are, and how
many people will come after them.
