Abstract
The prevailing narrative around population growth has long been dominated by alarmist predictions of overpopulation, resource scarcity, and environmental collapse. However, such views often lack nuanced understanding and empirical support. In this article, we will examine the myths around population explosion with the help of Renowned Swedish statistician Hans Rosling, and some other scholars. These experts have argued against the simplistic notion that population growth is humanity’s greatest challenge. This article examines the myth of dangerous population growth, referencing Hans Rosling’s groundbreaking work and insights from other experts. Through an exploration of historical trends, demographic data, and technological advancements, this article illustrates how humanity is poised to tackle the challenges of population growth and environmental sustainability effectively.
The Myth
Overpopulation. In 1800, the world Population was 1 billion. Today, the world population is 7 billion, by 2100, it is expected to be around 11 billion. It’s true but at the same time Overpopulation is a word that has haunted humanity for centuries, conjuring visions of overcrowded cities, dwindling resources, and environmental doom. But—is it accurate? The roots of this fear lie deep in history, with Thomas Malthus’ grim predictions of famine and societal collapse. Fast forward a couple hundred years, and Paul Ehrlich’s The Population Bomb reignited those fears, painting an apocalyptic picture of an overburdened planet. Yet, as the dust of these claims settles, data tells a far more nuanced—and hopeful—story.

Hans Rosling, the renowned Swedish statistician, spent his career combating misconceptions about global development. He used data not just as a tool, but as a story-telling device, unraveling myths and replacing them with a more grounded perspective. His work reveals that population growth isn’t the ticking time bomb many imagine—far from it. And he wasn’t alone; scholars like Amartya Sen and Joel Cohen add to this narrative, showing how human ingenuity and equitable development reshape this age-old debate. This article aims to delve into that conversation, shedding light on the truths behind the myth of runaway population growth.
Historical Trends in Population Growth
The Demographic Transition Model
Population growth isn’t static; it ebbs and flows with societal changes. Enter the Demographic Transition Model (DTM), a framework that helps decode these shifts. It’s a bit like moving through the gears of a car—each stage reflects a different phase of societal evolution:
- Pre-Industrial Stage: High birth rates, high death rates. Population? Stuck in neutral. Life expectancy averaged around 30-40 years, birth rates as high as 7-10, with survival more a matter of luck than longevity.
- Transitional Stage: Death rates plummet—think better sanitation, healthcare, and food security. Birth rates, however, stay high for a while, causing populations to soar. For example, Bangladesh saw its population swell during the mid-20th century as its infant mortality dropped sharply. Life expectancy more or less same.
- Industrial Stage: The game changes. Urbanization, education, and economic growth usher in lower birth rates. In India, fertility rates fell from 5.9 children per woman in the 1950s to just 2.0 in 2023, largely thanks to improved literacy rates and access to contraception.
- Developed Stage: Stability. Birth and death rates level off, or even decline, as seen in much of Europe and East Asia. Countries like Japan now grapple with shrinking populations, not growth.
Let’s layer in some numbers: in 1950, global life expectancy hovered around 48 years. By 2023, that figure had jumped to 73 years. In Sub-Saharan Africa, where life expectancy had lagged, it’s now approaching 64 years, driven by reductions in child mortality and better access to healthcare. Birth rates, too, tell a striking tale. Globally, fertility rates dropped from 5.0 children per woman in 1950 to 2.3 in 2023—an astonishing shift that reshaped the demographic landscape.
Hans Rosling viewed that countries like Bangladesh and Vietnam, once written off as population disasters, are now shining examples of progress. In the 1970s, Bangladesh had a fertility rate of 6.9 children per woman. Today? It’s just 2.1—replacement level. This didn’t happen by chance; education, access to contraception, and community health programs have done wonders, despite all the issues.
Statistical Evidence
The narrative that “more people equals disaster” often fails to consider this demographic transition. Yes, global population has ballooned—from 2.5 billion in 1950 to 8 billion in 2023. But the growth rate is slowing. The UN predicts that by 2100, the world population will plateau at around 10.4 billion. Africa is the last region experiencing rapid growth, but even there, the pace is expected to slow as development takes root.
Population Growth and Resource Scarcity: Separating Fact from Fiction
Food Production

“We won’t have enough food!” It’s a common refrain. Yet history proves otherwise. Since the 1960s, global food production has soared by over 150%, while population grew by just 140%. How? The Green Revolution brought high-yield crops, better irrigation, and fertilizers. India, once a poster child for famine, now has become a net exporter of food. By 2020, India’s grain production had quadrupled compared to 1960 levels.

But Hans Rosling often pointed out a critical nuance: the problem isn’t production, it’s waste. About one-third of food produced globally is wasted—enough to feed 1.6 billion people. Efficient distribution systems and reducing food waste could ensure that no one goes hungry.
Energy and Resources

Concerns about resource depletion often miss the mark. Renewable energy is scaling up dramatically. In 2023, renewables accounted for 30% of global electricity generation—a leap from just 5% in 2000. Solar panels now common across Africa, bringing electricity to villages for the first time. Recycling, too, is changing the game. Europe recycles over 50% of its aluminum, drastically reducing the need for raw materials.
It’s worth noting that population growth often correlates with innovation. More people mean more minds to solve problems. Joel Cohen’s work highlights this dynamic, arguing that humanity’s carrying capacity isn’t fixed—it evolves with technology and culture.
Environmental Sustainability and Population Growth
Urbanization and Efficient Living
Cities, often demonised as overcrowded, are paradoxically the key to efficient living. Urban areas concentrate resources and services. Think public transport, waste management, and energy grids. In Lagos, Nigeria, for instance, urbanization has spurred economic growth, though challenges remain in infrastructure development.
Hans Rosling loved to emphasise this point: cities are hubs of innovation and efficiency. A family in rural Africa might burn firewood for cooking, but urban households are more likely to use cleaner, more efficient energy sources.
Climate Change and Consumption Patterns
Here’s the twist: population size isn’t the main driver of climate change—consumption is. High-income countries, with relatively stable populations, are the biggest polluters. The average American emits 16 tons of CO2 annually. Compare that to the average Nigerian: just 0.7 tons. So developed countries only need to focus more on to curb carbon emmissions.
Focusing solely on population growth in developing countries distracts from the real issue: unsustainable consumption in wealthier nations. Tackling climate change means rethinking how we produce and consume, not blaming those with the least impact.
The Role of Education and Economic Development
Women’s Education and Empowerment
Hans Rosling’s data-driven storytelling often circled back to one core solution: educate women. The impact is staggering. In Sub-Saharan Africa, where female literacy is rising, fertility rates are falling. Niger, with one of the highest birth rates globally, is seeing change as girls’ education expands.
Take Bangladesh again. In the 1970s, before Independence, girls rarely attended school, and the average woman had six or seven children. Today, nearly every girl completes primary education, and fertility rates have plummeted to 2.1 children per woman.
Economic Growth and Health Outcomes
Economic development and health improvements go hand in hand. In India, rising incomes have lifted millions out of poverty, while life expectancy climbed from 40 years in 1950 to over 70 years in 2023. Better healthcare, lower infant mortality, and family planning programs have all played a great role. Hans Rosling frequently emphasised that economic growth isn’t the enemy; it’s a catalyst for sustainable development.
Conclusion
The myth of dangerous population growth falls apart under scrutiny. Fertility rates are dropping, life expectancy is rising, and human ingenuity continues to outpace the challenges we face. Hans Rosling’s work—along with insights from other thinkers—offers a clear message: focus on solutions, not fear.
Yes, challenges remain. Africa’s rapid growth needs careful planning, and climate change demands urgent action. But the answers lie in empowering people—through education, healthcare, and equitable development—not in perpetuating outdated myths. Humanity has the tools, and the data, to build a sustainable future. The question is: How will we use them?
