This municipality is famous for its duck-raising industry and especially for producing balut, a Filipino delicacy, which is a boiled, fertilized duck egg. Pateros is also known for the production of red salty eggs and "inutak", a local rice cake. Moreover, the town is known for manufacturing of "alfombra", a locally made footwear with a carpet-like fabric on its top surface. Pateros is bordered by the highly urbanized cities of Pasig to the north, and by Taguig to the east, west and south.

Pateros is the smallest municipality both in population and in land area, in Metro Manila, but it is the second most densely populated at around 37,000 inhabitants per square kilometer or 96,000 inhabitants per square mile after the capital city of Manila. Unlike its neighbors in Metro Manila, Pateros is the only municipality in the region.
