UN-Habitat's World Cities Report 2026 estimates that up to 3.4 billion people lack access to secure, safe and adequate housing, including more than 1.1 billion people in informal settlements and slums.
What this does not establish
The estimate does not mean all affected people experience the same deprivation or legal status.
Counterevidence & uncertainty
National definitions and underlying vintages vary; the report presents an upper-bound formulation.
What would change the reading
Update when UN-Habitat releases revised statistical annexes or national census-based series.
