Stand On New York

The Washington Post has one of those Gee Whiz posts about, well you'll see:

If all the world’s people squished together, how much room would they take up?

If all the world’s people stood really close, how much room would they take up? You probably haven’t had the time or inclination to consider this question, which is why you should be grateful for Tim Urban of the blog Wait But Why. Urban chose to investigate this question in a recent post with lots of enlightening calculations and fun graphics.

Urban’s core assumption is that 10 humans can fit in a square meter. If you watch this video of nine journalists squeezing themselves into a square meter, you can see that while this would be cozy, it’s definitely possible. This especially true given that about a quarter of the world’s population is under 15.

At 10 people per square meter, that means we can fit 1,000 people in a 10-by-10-meter square. 54,000 people can fit in an American football field, and 26 million people – about the population of Scandinavia – can fit into one square mile, Urban writes. Central Park, which is 1.3 square miles or 3.4 square kilometers, could hold the population of Australia or Saudi Arabia. All 320 million Americans could huddle together into a square that is 3.5 miles or 5.7 kilometers on each side.

And what if we found a piece of land for everyone on Earth – all 7.3 billion of the world’s people? Urban calculates that we would need a square that is 27 km, or 16.8 miles, on each side – an area smaller than Bahrain and, yes, New York City.

Simple mathematical stuff, and amusing, if not particularly meaningful. But it staggers me that someone could write such an article without mentioning the classic SciFi novel "Stand on Zanzibar".

Stand on Zanzibar is a dystopian New Wave science fiction novel written by John Brunner and first published in 1968. The book won a Hugo Award for Best Novel at the 27th World Science Fiction Convention in 1969, as well as the 1969 BSFA Award and the 1973 Prix Tour-Apollo Award.

The primary engine of the novel's story is overpopulation and its projected consequences, and the title refers to an early twentieth-century claim that the world's population could fit onto the Isle of Wight – which has an area of 381 square kilometres (147 sq mi) – if they were all standing upright. Brunner remarked that the growing world population now required a larger island; the 3.5 billion people living in 1968 could stand together on the Isle of Man (area 572 square kilometres (221 sq mi)), while the 7 billion people who he (correctly) projected would be alive in 2010 would need to stand on Zanzibar (area 1,554 square kilometres (600 sq mi)). Throughout the book, the image of the entire human race standing shoulder-to-shoulder on a small island is a metaphor for a crowded world.

Christ, what an imagination I've got.
