Manila, the capital of the Philippines, is one of the most crowded cities on Earth. An estimated 200,000 people live in a single square mile in some neighbourhoods  — nearly three times the density of Manhattan.

In 2017, German photographer Bernhard Lang set out to capture the overpopulation crisis from above. The images show the residents’ living conditions as they are rarely seen. Lang shared some photos from his series with us. You can check out more of his work on Instagram and Facebook.
