Overcrowding occurs when a space, such as a city, building, or public transport, has more people than it can comfortably accommodate. This situation can lead to various problems, including increased stress, reduced quality of life, and strain on resources like water, food, and sanitation. In urban areas, overcrowding can result in traffic congestion, higher crime rates, and inadequate housing. It often affects public services, such as schools and hospitals, making it difficult for them to meet the needs of the growing population. Addressing overcrowding typically requires careful planning and management of resources.
