LEDC Rapid Growth
1. Rapid population growth in LEDCs
Towns and cities in LEDCs are growing rapidly,
and an increasing proportion of people are living
in cities. LEDCs are going through a period of
urban growth and urbanisation.
Your case study will either be Rio de Janeiro or
Sao Paulo
2. Cities in LEDCs are growing
due to:
- A high birth rate
- A low death rate
- Migration to the
cities
3. Migration to the cities
The population growth in LEDCs is
affecting both rural and urban areas.
The population of cities is growing
proportionally faster than that in the
rural areas
Push and Pull factors…..

Basic lack of services – medical, More entertainments and a ‘better’
educational, water, sanitation, lifestyle

Natural disasters such as drought or
flooding
5. The effects of rapid growth
• Increased air pollution from industries and traffic
• A severe shortage of land and very high land
prices – especially anywhere that is near to the
city
• A severe lack of housing – development of
favelas on the outskirts of the city.
• Lack of employment – most people living favelas
are employed in the ‘informal sector’
