The world is facing an unprecedented housing crisis. According to the latest UN-Habitat estimates, 318 million people are homeless, while 2.8 billion people—over a third of the global population—lack access to adequate housing. Behind these stark figures lie deep inequalities that undermine social progress and human dignity.

Adequate housing is more than shelter, it is a foundation for stability, health, education, and opportunity. Without a safe and secure home, individuals are more vulnerable to poverty, exclusion, and poor health outcomes. Homelessness also carries a heavy social cost, eroding trust, cohesion, and the potential for societies to thrive.

The housing challenge is global but manifests differently across contexts. In rapidly urbanizing regions, millions live in informal settlements or slums, where basic services are scarce and conditions unsafe. Today, 1.1 billion people live in such informal settlements, with 90 percent concentrated in Africa and Asia. Conflict, economic inequality, climate change, and natural disasters are major drivers of displacement and housing insecurity, pushing millions into precarious living conditions.

The urgency of the crisis was underlined at the UN-Habitat Assembly in Nairobi (29–30 May 2025), where Member States adopted the UN-Habitat Strategic Plan for 2026–2029. The plan places affordable housing, secure land tenure, and access to basic services at the heart of global priorities. Leaders called for bold and coordinated action, stressing that housing must be treated as a human right and a cornerstone of sustainable development.

The right to adequate housing is embedded in international human rights instruments and explicitly tied to the 2030 Agenda for Sustainable Development. Goal 11 commits the international community to make cities and human settlements inclusive, safe, resilient, and sustainable. Addressing homelessness and housing insecurity is therefore essential to achieving the SDGs and ensuring that no one is left behind.

Tackling homelessness and inadequate housing requires integrated strategies at local, national, and global levels:

• Scaling up affordable housing initiatives through innovative financing, public-private partnerships, and policy reforms.
• Expanding social protection systems to prevent families from falling into homelessness.
• Investing in resilient housing solutions to adapt to the realities of climate change and disasters.
• Strengthening community-based models such as cooperatives and housing associations that empower people to participate in shaping their own futures.

Homelessness is not inevitable. With coordinated action and commitment, the global community can reverse these trends. As the world prepares for the Second World Summit for Social Development in Doha, 4-6 November 2025, the message is clear: accelerating social progress requires that every person has access to a safe, secure, and dignified place to call home.
