The number of homeless people is rising in many countries. What are the reasons and how can this problem be solved?

In many countries homelessness has become a growing concern. Some observers attribute this trend mainly to macroeconomic pressures and a shortage of affordable housing, while others emphasize gaps in welfare systems and social support networks. I believe that both structural factors and individual circumstances interact to produce homelessness, and effective policy must address both sides.

First, economic hardship and a tight housing market are major drivers. When incomes do not keep pace with rising rents and utility costs, households become vulnerable to eviction and housing insecurity. In many cities, a shortage of affordable homes means even employed people struggle to find stable accommodation, leading to temporary or chronic homelessness. For example, lengthy wait times for social housing and persistent rent increases illustrate how economic and market conditions can push people onto the streets or into shelters.

Second, weaknesses in social safety nets and barriers to reintegration contribute to homelessness. People leaving prison or care facilities often lack stable housing, employment support, and access to essential services such as mental health care. Without targeted assistance—housing subsidies, job training, and reliable health services—these individuals are at high risk of returning to homelessness, creating a cycle that is hard to break.

My view is that a comprehensive policy mix is required. Expanding the supply of affordable housing, stabilizing rents through subsidies, and strengthening social services are essential steps. At the same time, targeted reintegration programs for people leaving prisons or care institutions, along with mental health and addiction support, can help individuals maintain housing and gain employment. The relative importance of these measures will vary by country, region, and local context, but a combination of housing-led and welfare-led interventions is likely to be most effective.

In summary, homelessness arises from a combination of economic pressures, housing shortages, and gaps in support systems. While the exact balance differs by context, government action that improves housing availability, provides financial and welfare assistance, and offers reintegration services is the most plausible path to reducing homelessness over time.
