Sub-Saharan Africa is the only region with substantial rural population growth in recent decades and will account for nearly all future rural growth [2].
GROWTH
Rural and city growth
The share of urban residents in slums was highest in sub-Saharan Africa in 2022 [6].
HOUSING
Informal settlements
Sub-Saharan Africa reached a record 38.8 million internally displaced people at the end of 2024 [15].

B.5How countries appear in the global edition
Countries enter the human systems edition through the demographic and city chapters of their own national editions, on one card grammar. They are read against peer distributions and thresholds, never placed in a league table.
| Card field | What it shows | Source |
|---|---|---|
| WEFH+B state | each core system against peer distribution bands | national edition |
| Couplings | the national dependency matrix | national edition |
| Risk objects | the national risk portfolio | national edition |
| Capability rungs | the national capability ladder | national edition |
| Evidence age | oldest and newest source dates | national source register |

How to read a country card
- Each system is shown against the distribution of its peers, with thresholds where they exist
- Couplings and risk objects come from the country’s own national edition
- Capability rungs record evidence, not a judgement of institutions
- Evidence age is printed, so older national data are visible as such
| Wave | Countries and unions | State |
|---|---|---|
| W0 | Canada | ISSUED |
| W1 | United States, United Kingdom, France, Germany, Italy, Japan, European Union, Switzerland | PLANNED |
| W2 | Mexico, Brazil, Argentina, Türkiye, Russian Federation, Saudi Arabia, United Arab Emirates, South Africa, Senegal, Kenya, African Union, India, China, Republic of Korea, Indonesia, Singapore, Australia | PLANNED |
