POPULATION
In 2020, the United Nations’ data revealed that almost 1.1 billion people had been living in slums or slum-like conditions. The UN estimates that by 2050, nearly two billion more individuals will be pushed to inhabiting such conditions.
The world is facing a growing habitat crisis, and the problem is of such pertinence that SDG target 11.1 is dedicated to demanding its solution. The target states: “By 2030, ensure access for all to adequate, safe, and affordable housing and basic services and upgrade slums.” In 2020, almost 14% of the world’s population dwelled in slums, 85% of whom were concentrated in three regions: Central and Southern Asia, Eastern and South-Eastern Asia, and Sub-Saharan Africa. The two Asian regions collectively had 662 million people living in slums, whereas Sub-Saharan Africa had 230 million.
The list of countries was adopted from the World Bank dataset, which lists the percentage of each country’s urban population that is living in slums. The countries are ranked in a descending order of the percentage of urban population living in slums, for the latest available year.
Further information for specific countries has been sourced from the Participatory Slum Upgrading Program (PSUP). PSUP is a program by the UN-Habitat that works to improve living conditions for slum-dwellers. Based on this methodology, here are 20 countries with the largest slum population in the world:
