Slum housing refers to poorly constructed, overcrowded, and often unsafe living conditions typically found in urban areas, where residents may experience poverty and limited access to essential services. This type of housing emerged during the rapid urbanization of the late 19th and early 20th centuries, highlighting significant social and economic disparities in society. Slum housing is often associated with inadequate infrastructure, high population density, and a lack of basic amenities such as clean water and sanitation.
