UN-Habitat Warns of Unprecedented Global Housing Crisis

The United Nations Human Settlements Programme (UN-Habitat) has called for urgent, coordinated action from governments, businesses, civil society and local communities to tackle the worsening global housing crisis. This appeal features prominently in UN-Habitat’s World Cities Report 2026, which insists that only integrated, sustained and inclusive strategies can achieve universal access to safe, affordable housing. The report paints a stark picture: billions of people worldwide lack adequate shelter, while nearly half of all households struggle to afford their homes.

According to the findings, rising costs, limited housing supply, mass displacement and expanding informal settlements have combined to create one of the most difficult global challenges of this century. The report identifies five interconnected drivers behind the global housing crisis: affordability, displacement, informality, sustainability and liveability. It stresses that housing has long been sidelined in international development planning, despite its critical role in supporting health, education, wellbeing and social inclusion.

UN-Habitat is urging governments to treat adequate housing as a central pillar of sustainable development rather than an afterthought. The report states that national development frameworks should recognise housing’s power to improve health outcomes, expand economic opportunity, build climate resilience and strengthen social bonds. It also links housing directly to progress across multiple Sustainable Development Goals, arguing that investment in this area produces benefits that ripple across society and the economy alike.

Rather than focusing narrowly on building numbers, the report calls for housing policy that addresses every dimension of adequacy, including secure tenure, affordability, service access, habitability, location, cultural relevance and environmental sustainability. It recommends that countries pursue balanced strategies covering both housing demand and supply, such as strengthening land governance, expanding rental and non-market housing options, simplifying regulations, and creating financing tools tailored to low-income and vulnerable groups.

The scale of the problem, according to the report, is staggering. Up to 3.4 billion people globally lack access to adequate housing, including over 1.1 billion living in informal settlements, the highest number ever recorded. Displacement figures have also surged, with growing numbers of refugees and internally displaced people living in precarious urban conditions. Meanwhile, housing affordability continues to worsen: 44 per cent of households worldwide spend more than 30 per cent of their income on rent, a figure that climbs to 55 per cent across Sub-Saharan Africa.

The report attributes these deepening housing deficits to structural forces, including rapid urbanisation, soaring land values, widening inequality, and the growing treatment of housing as a financial investment rather than a basic need. By 2050, cities are expected to absorb an additional two billion residents, placing even greater strain on already overstretched housing systems.

Climate change compounds the crisis further. The report projects that climate-related hazards could destroy 167 million homes by 2040, while natural disasters caused $280 billion in global economic losses in 2023 alone, much of it uninsured. UN-Habitat warns that without accelerated climate adaptation, cities and infrastructure will face mounting risks, particularly in rapidly growing and vulnerable urban areas.

Ultimately, the report calls for restoring balance between housing’s social purpose and its economic value, cautioning that treating housing purely as a speculative asset undermines both community wellbeing and responsible investment.
