Summary of “Hans Rosling: Global population growth, box by box”

Hans Rosling uses a simple, analog teaching tool—boxes representing one billion people each—to illustrate changes in global population and economic development from 1960 to the present (2010) and project into the future (2050). He challenges outdated worldviews about “the West” and “the Developing World,” showing how the global population and economic realities have shifted dramatically.

Main Ideas and Concepts

1960 World Population and Economic Divide

The world population was 3 billion: 1 billion in the industrialized (Western) world, 2 billion in the developing world.
The industrialized world was wealthy, healthy, educated, with small families and aspirations like buying cars (e.g., Swedes saving for Volvos).
The developing world struggled with poverty, food scarcity, and large families, aspiring only to basic needs like shoes.
This created a large economic and social gap, reflected in the language and mindset dividing “the West” and “the Developing World.”

population growth and Economic Changes (1960–2010)

Since 1960, the world population doubled, adding 4 billion people.
The industrialized world grew economically and shifted aspirations from car ownership to international travel.
Some developing countries have become emerging economies, buying cars and growing wealth (e.g., China acquiring Volvo).
However, about 2 billion people remain very poor, nearly as poor as 50 years ago.
A new “middle” group of about 3 billion people is emerging, relatively healthy and educated, with family sizes of 2–3 children, aspiring to own bicycles and motorbikes.
The economic and social gap between the richest and poorest has widened, but there is now a continuum from poverty to wealth.

Future Projections (to 2050)

Emerging economies like China will continue to grow and catch up economically, moving towards higher consumption and owning electric cars, provided investments in green technology are made.
The poorest 2 billion people will grow to 3–4 billion due to higher birth rates and lower child survival rates.
population growth will only stop if the poorest populations escape poverty, gain education, and improve child survival rates.
Without improvements, continued population growth and poverty will persist.
Achieving sustainable population levels (~9 billion) depends on improving child survival and family planning.

child survival as Key to Population Control

Using digital data visualization, Rosling shows that as child survival rates improve (above 90%), family sizes decrease.
Poor child survival leads to large families and rapid population growth.
Investments by organizations like the Gates Foundation, UNICEF, and governments in health and education are crucial to improving child survival and stabilizing population growth.
“child survival is the new green”—improving child survival is essential for sustainable population and environmental outcomes.

New Worldview and Role of the West

The old division between the West and Developing World is obsolete; the world is interconnected with a continuum of economic levels.
The West’s future role is to be a foundation and partner in the modern world, not a dominant leader.
Global cooperation, green technology, poverty alleviation, and good governance are necessary for a just and sustainable world.
Rosling identifies himself as a “possibilist”—analytical and hopeful about the future, grounded in facts rather than optimism or pessimism.

Methodology / Instructional Approach

Use of analog teaching tools (boxes representing one billion people) to visualize population changes.
Use of digital data visualization (country bubbles showing population size, child survival rates, and fertility) to demonstrate demographic transitions over time.
Emphasis on interpreting population growth through child survival and family size relationships.
Advocates for investments in health, education, family planning, and green technology to achieve sustainable development.
Encourages updating mental models and language about global development to reflect current realities.
