BLOG – If Everyone Lived at the Same Density As Hong Kongers… 10


Over the summer, two sets of maps showing population density (here and here) went viral. Each of the them demonstrated how much land would be required for the entire human race if everyone lived at a similar density as a chosen country. However, Hong Kong – which has one of the highest population densities in the world – was not included.

Thus, Hong Wrong did the maths and below is a map showing how Earth’s entire human population could relocate to Egypt if they adopted HK’s high-rise lifestyle…

Mongkok is home to 130,000 people per square kilometre, whilst Hong Kong itself boasts 6,544 people per square kilometre.

Yet most of Hong Kong is countryside – less than a third of the territory is urbanised…

The highest population density at which humans have ever lived would be within the old Kowloon Walled City.

    Perhaps I’ve done the maths incorrectly here, but I think your calculations are wrong.

    According to Wikipedia, the area of Jamaica is 10991 square kilometres, and you said Hong Kong has a population density of 6544 people per square kilometre, so if we calculate 10991*6544, you get 71,925,104, which is 71 million, whereas the population of earth is 7.1 billion, or 7,100,000,000

    Am I right or have I misunderstood something in my calculation?

      Quite right. Someone spotted it on Twitter too and I’ve since made the correction. How embarrassing. Turns out I’d mixed up my tens-of-millions with my billions.

    That is an amazing stat. Can’t imagine the human population living in Egypt. Wonder what rent would be like to live in the Spinx?

    If the entire population of the world lived a la the Walled City, how much space would we need then?

      At 1,225,000 people per square km, the population could fit in any place around 6000 km, like Delaware
