MYP Individuals & Societies Social Challenges Notes

How Do Social Challenges Emerge In Urban Systems?

1. Social challenges in cities usually come from the same basic mismatch: urban populations can grow faster than housing, jobs, and public services.
2. When that happens, cities tend to see predictable patterns:
   1. Housing stress: overcrowding, rising rents, informal settlements.
   2. Service gaps: unequal access to clean water, sanitation, healthcare, and schooling.
   3. Job insecurity: informal work and unemployment, especially for recent migrants.
   4. Segregation and inequality: wealth and poverty cluster in different neighbourhoods, creating unequal life chances.

Why Does Rapid Urban Growth Increase Social Pressure?

1. Rapid urban growth increases demand for housing, services, and infrastructure faster than cities can expand them.
2. This mismatch produces overcrowding, particularly in low-income and informal areas.
3. Overcrowding matters because urban systems scale poorly under density stress.
4. Waste collection, sewage treatment, and water supply are designed for a certain number of users.
5. When population density rises sharply:
   1. Waste accumulates faster than it can be collected,
   2. Drainage systems block more frequently,
   3. Shared sanitation facilities become unsafe.
6. These conditions increase the spread of waterborne disease, reduce productivity through illness, and place long-term pressure on healthcare systems.
