Population living in slums 2023

In 2023, South Sudan has the highest percentage of its population living in slums at 94.20%, while the global range for this statistic extends from -1.14% to 94.20%. The global average percentage of people living in slums is 21.45%, highlighting significant disparities in urban living conditions across different countries.

Economic and Political Drivers of Slum Populations

The prevalence of slum populations is often a reflection of economic and political instability. In South Sudan, where 94.20% of the population lives in slums, ongoing conflict and economic challenges severely limit infrastructure development and housing improvements. Similarly, Chad and the Democratic Republic of the Congo have high slum populations at 81.46% and 79.03% respectively, driven by economic hardship and inadequate governance that hampers urban planning and resource allocation.

In contrast, countries with robust economies and stable political environments, such as Kyrgyzstan and Kazakhstan, show negative values in slum population statistics, indicating effective urban management and housing policies. These countries have percentages of -1.14% and -0.53% respectively, suggesting successful mitigation of slum conditions through effective policy interventions.

Impact of Urbanization on Slum Growth

Rapid urbanization without corresponding urban planning can exacerbate slum conditions. In Mali and Afghanistan, where slum populations are 77.04% and 73.24%, the swift migration of people to urban areas in search of better economic opportunities has outpaced the development of adequate housing and infrastructure. The lack of affordable housing options forces many into slum settlements.

Conversely, countries with strategic urban planning and investment in housing infrastructure, like Oman and Andorra, report negligible or zero slum populations. These nations have successfully managed urban growth by ensuring that housing developments keep pace with population increases, thereby preventing the formation of slums.

Year-Over-Year Trends and Policy Implications

Analyzing year-over-year changes provides insight into the effectiveness of recent policies and economic shifts. Burkina Faso saw the most significant decrease in slum populations, with a reduction of -22.85% (a -26.0% change), indicating successful interventions in housing and urban development. Similarly, Mali and Tuvalu experienced substantial declines of -15.45% and -15.09%, respectively, demonstrating the impact of targeted policies.

On the other hand, countries like Comoros and Jordan have experienced increases in slum populations by +6.02% and +5.25%. These rises may reflect recent economic challenges or insufficient urban planning in the face of rapid demographic changes, emphasizing the need for policy adjustments to address housing shortages and improve living conditions.

Regional Disparities and Environmental Factors

Environmental factors also contribute to the regional disparities in slum populations. In regions prone to natural disasters, such as Angola with a slum population of 66.66%, the destruction of housing infrastructure can lead to increased slum dwellings. Countries with better disaster management and resilient infrastructure, like Netherlands and Aruba with 0% slum populations, demonstrate how environmental preparedness can prevent slum proliferation.

Furthermore, the presence of slums in countries like Niger and Central African Republic, with percentages of 70.44% and 68.91%, respectively, highlights the interaction between poverty, inadequate infrastructure, and environmental challenges, necessitating comprehensive strategies that integrate economic, environmental, and social policies to mitigate slum growth.
