Informal settlements
- When cities grow faster than housing, informal settlements 非正规住区 (slums) form.
- They often lack clean water, sanitation, and secure land rights.

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.
