A squalid neighborhood is an area of a city or town that is characterized by poverty, dilapidated buildings, and a lack of basic services. It is often referred to as a SLUM, which is a term used to describe a densely populated urban area with a high rate of poverty and poor living conditions. Squalid neighborhoods are often found in large cities and can be the result of a variety of factors, including economic inequality, inadequate housing, and a lack of access to basic services.
