The most congested islands on earth (2)

Lubeck, Germany

The old town of Lubeck is situated on an island, surrounded by waterways. It's now part of the Unesco World Heritage List

The old town of Lubeck was founded in 1143 on an island on the Baltic coast of northern Germany. The island is surrounded by land but cutoff from the mainland by waterways.

There's no clear numbers on the number of people still living in the historic centre but as aerial images show, it is densely packed with buildings and a network of streets.

The rest of modern day Lubeck is relatively spacious though, with about 212,000 people living on approximate 83 square miles of land according to the UN.

Manhattan, USA

Manhattan is what most people think of when they talk about New York. The island is packed with high rises and skyrocketing rents have forced many to move to neighbouring areas

Bustling Manhattan is what many people think of when they think about New York.

But the borough is so densely populated that many who can't afford the high rental rates are forced out into the surrounding boroughs of New York City and even nearby states.

There's only about 23 square miles of land but an estimated 1.626 million people living on it - the equivalent of 70,700 people per square mile.
