Squatting: informal occupation of vacant land and buildings

Characteristics and common forms

Squatting takes several forms depending on context and intent. Residential squats are dwellings established by homeless or low-income people seeking shelter. Informal settlements and shantytowns—often called favelas, slums or barrios in different countries—can grow when large numbers of households occupy land on the urban fringe. Other forms include temporary occupation of disused industrial premises, collectivized spaces used for cultural or political projects, and agricultural squatting on unused rural land.

Why squatting happens

• Housing shortage and affordability crises that leave people without legal options.
• Poverty and displacement driven by economic or social change.
• Political or artistic movements that use occupation to protest policy, create autonomous zones, or repurpose unused assets.
• Opportunistic use of long-abandoned buildings where enforcement is weak.

Legal responses and outcomes

Responses to squatting vary by jurisdiction. In some places, authorities carry out evictions and criminal prosecutions; in others, long-term occupation can lead to legal recognition through doctrines such as adverse possession or formal regularization programs. Municipalities sometimes negotiate with occupants to provide services, convert squats into social housing, or relocate residents. Enforcement, humanitarian concerns and political considerations shape whether occupants are removed, tolerated, or integrated into official housing plans.

History, movements and notable examples

Squatting has a long history wherever property rights, urban change and inequality intersect. In the 20th and 21st centuries, it has appeared both as a symptom of rapid urbanization and as a deliberate strategy of protest and self-organization. One well-known example is Freetown Christiania, a self-declared autonomous community established in Copenhagen in the 1970s that developed from a squatted military zone into a distinctive neighborhood with its own norms and legal disputes. Broader estimates of global informal settlement populations vary; for instance, a 2004 proposal by a scholar suggested very large numbers of people living informally worldwide, but precise counts are contested.

Importance and distinctions

Squatting raises complex questions about the right to housing, property law, urban planning and social justice. Distinctions matter: emergency shelter occupations differ from long-standing informal neighborhoods; politically motivated squats contrast with survival-driven settlements. Policymakers balance property rights, public safety and human needs when deciding whether to enforce evictions, offer alternatives, or pursue regularization.
