Overcrowded refers to a situation where a space, typically urban, has more people than it can adequately support, leading to various social, environmental, and economic issues. This condition often arises in cities experiencing rapid population growth, inadequate infrastructure, and limited resources, which can strain public services and reduce quality of life for residents. Overcrowding can result in traffic congestion, pollution, and an increase in crime rates as communities become stressed under the weight of too many inhabitants.
