A world of 8 billion: Towards a resilient future for all – Harnessing opportunities and ensuring rights and choices for all
The world’s population surpassed 7 billion people in 2011. The number will reach 8 billion this year, triggering the appropriate reactions. Some people will be in awe at the advances in medicine that have increased lifespans, decreased infant and maternal mortality, and sped up the discovery of vaccines.
However, not everyone has experienced growth, which brings inequity into stark contrast. Climate change, violence, and discrimination are still issues today or have gotten worse since they were first brought up 11 years ago.
The population of the globe increased to 1 billion people after hundreds of thousands of years, and then it increased sevenfold in just another 200 years or so. The world’s population crossed the 7 billion threshold in 2011, is projected to reach about 7.9 billion in 2021, and to rise to almost 8.5 billion in 2030, 9.7 billion in 2050, and 10.9 billion in 2100.
Fertility rates and life expectancy have undergone significant recent shifts. Early in the 1970s, women had an average of 4.5 children each; by 2015, the global fertility rate had dropped to under 2.5 children per woman. Globally, average lifespans have increased as well, going from 64.6 years in the early 1990s to 72.6 years in 2019.
Additionally, global urbanization is at an advanced degree, and migration is speeding up. Around 66 percent of the world’s population will reside in cities by 2050, marking the first year in which urban populations outnumbered rural ones.
These megatrends have broad repercussions. They have an impact on social security, income distribution, poverty, and economic progress. They also have an impact on initiatives to guarantee that everyone has access to energy, water, food, housing, sanitation, and health care. Policymakers need to know how many people are now living on the planet, where they are located, how old they are, and how many will follow them in order to meet individual needs in a more sustainable manner.
