Where Half the World Lives

With the world’s population now around 7.5 billion, and projected to grow by another 4 billion or so within a century, one could be forgiven for imagining the world as already swelling to the brim with people.

Yet as the following map designed by Max Galka shows, much of the world is fairly empty, and will likely remain so given the pace of urbanization (wherein more people live and work in less land).

That means roughly 3.75 billion people live in an area constituting just one percent of the world’s total landmass. Continue reading

Global STEM Leaders

STEM — short for science, technology, engineering, and mathematics — is all the rage these days, as economies across the world become more knowledge-based, and as humanity faces threats like climate change and resource depletion that will require creative, technological solutions.

That’s why so many nations, especially in the developing world, are trying to gain a competitive advantage by investing in STEM education and seeking to attract STEM graduates from abroad. According to Forbes, which cites a report from the World Economic Forum, these are the countries leading the way:

Unsurprisingly, with their large and youthful populations, India and China have the most graduates overall at 78 million and 77.7 million, respectively. The U.S. is in third place with 67.4 million graduates, although the quality of its degrees may be greater than that of its competitors, whose education infrastructure is younger, less developed, and less prestigious (for now).

Japan’s high ranking is not surprising given that is a well established scientific and economic powerhouse, although its aging population and low rate of immigration likely explains why it doesn’t rank higher despite a population of 126 million. Russia, Iran, and Indonesia are rarely touted as academic leaders, but each is fairly populous — at 147 million, 75 million, and 260 million respectively — and Russia and Iran in particular have a long history of scientific achievement.

However, China may soon close this gap as it continues to improve its institutions and education standards:

Some estimates see the number of Chinese graduates aged between 25 and 34 rising 300 percent up to 2030 compared to just 30 percent in the U.S. and Europe. According to the World Economic Forum, STEM (science, technology, engineering and mathematics) has become a pretty big deal in China’s flourishing universities. In 2013, 40 percent of Chinese graduates finished a degree in STEM, over twice the share in American third level institutions

In an increasingly globalized world, the ability to draw and retain students and graduates from around the world will likely become a bigger consideration for more countries. For all the complexities of its visa and customs systems, the U.S. has long enjoyed an edge in this regard — for example, all six of its 2016 Nobel Prize winners were foreign-born.

But a wave of nativism and xenophobia may undercut its attractiveness as a research and academic hub, and other countries — including neighboring Canada — have begun to step up as alternative options, dangling such incentives as a path to citizenship upon graduation.

One thing is for certain. The future of a nation’s success and survival will depend on its command of technology and science. How it goes about advancing those intellectual resources is a different matter altogether. But any country’s increasing education is humanity’s gain.
