The world's population has been increasing at an alarming rate, resembling the shape of a hockey stick for centuries. It's a familiar scenario for anyone who has experienced the dreaded rush hour on public transport, squeezed between a sweaty armpit on one side and a train window on the other. But according to experts at the UN, this might soon become the reality for the entire world.
To put things into perspective, a baby born today will be 54 years old in 2080, when the UN predicts the world's population will peak at a staggering 10.3 billion. This is a significant increase from the turn of the 19th century when there were fewer than 1 billion people on Earth. It took more than a century for the population to double, but now, as you read this, there are over 8 billion people living their lives, going to work, and hopefully, reading The Agency.
The World Population Prospects 2024 report states that factors such as increased life expectancy, lower child mortality rates, and smaller family sizes have contributed to this population peak, which is expected to happen in the next 60 years. While this projection may seem daunting, it is actually lower than previous estimates. It is also expected that after this peak, the growth rate will drop for the first time since the Black Death 700 years ago, ultimately stabilizing at 10.2 billion by the end of the 21st century.
But even with this lower projection, the numbers are still significant. According to the UN, India will become the most populated country in 2100, followed by China, Pakistan, Nigeria, and the Democratic Republic of Congo. The United States will come in at sixth place, with a population of 421 million. These numbers signify a significant shift in the world's demographics, with people aged 65 and over projected to outnumber those under 18 in the 2080s. And by the next decade, there will be more people over 80 than babies.
However, it's not all bad news. The UN also predicts that there is a one in four chance that your country's population has already peaked and will now start to decrease. This is the case for 63 countries, including China, Germany, Japan, and Russia. In other countries like Brazil, Iran, Turkey, and Vietnam, the population will peak by 2054. But for the United States, India, and 121 other countries, the population will continue to increase throughout the century.
One major factor contributing to these changes is the decline in fertility rates and the aging of populations. Countries like France, Sweden, and the UK are projected to continue increasing in population size, albeit at a slower pace, while countries in Africa will experience rapid population growth. This growth poses a challenge for these nations to balance economic growth with sustainable resource consumption, especially considering the effects of climate change.
But the UN report also highlights the progress humanity has made in terms of living standards, with longer lives, healthier children, and better education. And the empowerment of women has played a significant role in offsetting the negative effects of population growth, contributing to the earlier than expected population peak. Initiatives such as increasing the legal age of marriage, promoting education, and providing support for caregiving and homemaking have all contributed to this progress.
Looking towards the future, there are steps that can be taken to address the challenges posed by a growing population. Governments must work towards decreasing teenage pregnancies and promoting access to sexual and reproductive health care, particularly in lower-income countries. Investments in education, public health, and sanitation are also crucial in managing population growth.
In the words of UN Secretary-General António Guterres, "everyone counts." By ensuring that marginalized communities have access to resources and opportunities, we can accelerate progress for all. As daunting as the numbers may seem, it's essential to remember the progress we have made and the potential for positive change in the future.
