Informal settlements (slums) form when housing lags behind growth.
The fastest urban growth today is in the developing world, not the developed. Do not picture urbanization as a mainly Western story — the biggest new megacities and the largest informal settlements are in Asia, Africa, and Latin America.
A developing-world capital doubles in a decade as migrants arrive from the countryside. Housing cannot keep up, so vast informal settlements spread on the edges — a fast-growing megacity with millions living without secure services.
Developing cities urbanize fastest today, mainly by migration. A megacity exceeds 10 million people. Where growth outpaces housing, informal settlements (slums) form, often lacking water, sanitation, and land rights.
