The chart that shows how much of a country's population lives in the biggest cities

Human beings like company, and we've always clustered together to form villages, towns and cities.

Data journalist Thomas Baekdal was intrigued to find out what percentage of people live in megacities after finding out that about 20 per cent of Turkey lives in Istanbul.

He decided to use World Bank data to see what the case was everywhere else, which Statista has mapped:

While the city state of Singapore is obviously 100 per cent urban, as can be seen on the infographic, it's not usual for more than 10 per cent of a country's total population to be concentrated in one place. 15.8 per cent of the UK lives in London, and 10.3 per cent of Brazil lives in Sao Paulo, as Baekdal points out.

China and India - the two countries with the largest populations - have comparatively tiny amounts of people living in Shanghai and Mumbai, their biggest cities.
