In urban planning, overcrowding specifically measures housing density where resident numbers exceed structural capacity.

The story behind the word. Combines Old English 'ofer' (beyond measure) and 'crūdan' (to press together or push into a tight space). In the 19th century, public health reformers coined 'overcrowding' as an official legal metric to combat toxic tenement housing conditions.
