What Are Slums?
Slums are densely populated urban areas with inadequate housing, insecure tenure, and limited access to basic services such as water, sanitation, and electricity. They often emerge when rapid urbanization outpaces infrastructure and affordable housing supply.
Global Scale and Trends
According to the United Nations Human Settlements Programme, over one billion people worldwide live in slum conditions, with the highest concentrations in sub-Saharan Africa, South Asia, and East Asia. Many residents work in informal sectors, facing low wages and social exclusion.
Economic and Social Challenges
Slums world conditions can limit economic mobility, increase health risks, and strain public services. Residents often lack formal credit, making it harder to invest in home improvements or start businesses. Targeted investments in infrastructure, land rights, and basic services can help reduce poverty and support inclusive urban growth.
