The most congested islands on earth (3)

Santa Cruz del Islote, Colombia

Despite measuring just 0.004 sq mi, 1,200 people have somehow managed to squeeze on to Santa Cruz del Islote. The Caribbean islet two hours from Cartagena, Colombia, is four times more densely populated than Manhattan

Santa Cruz del Islote is frequently considered one of the most densely populated places in the world and has about four times more densely populated than Manhattan.

There approximately 1,200 people living on the tiny 1 hectare (about 0.004 square mile) island or the equivalent of about 300,000 people per square mile.

Despite this, and the fact that there's no cemetery, no doctors or even running water, its residents still describe it as a paradise.

Ap Lei Chau, Hong Kong

Hong Kong is already known for being densely populated but the offshoot of Ap Lei Chau is even more packed with high rises

Ap Lei Chau is just off the south coast of the main Hong Kong Island.

Locals say that it's shaped like the tongue of a duck, gaining it the nickname of Duck Tongue Island.

There's about 87,000 people living on the island, which offers just half a square mile of space - meaning the population density is around 174,000 people per square mile.
