Rapid urbanization in poorer parts of the world has led to the development of squatter settlements that house over 50% of some city populations. Squatter settlements are informal and illegal communities built on unused land without basic infrastructure or amenities. Residents live in makeshift shelters with limited access to clean water, sanitation, healthcare, education, and other services. As a result, living conditions are poor and residents face higher risks of waterborne diseases, malnutrition, crime, and other issues affecting their quality of life.
