- Population
- Population change
- Mainly due to differences between birth rate and death rate.
- Key words: Exponential growth - a rate of increase which quickly doubles.
- Reducing growth
- wars/disease/ famine/natural disasters
- MEDC have a small birth rate due to contraception. More jobs for women.
- LEDC's have a high birth rate due to them being needed to supports their parents but also due to lack of contraception.
- Patterns of people
- Some densely packed places are where food can be grown e.g rivers/deltas.
- Less densely packed places can be harder places for people to live in e.g cold environments/mountains/ desserts
- Some places that are over populated for people to have a good standard of living
- Coping with increasing population
- Pressures on the land
- Problems servicing healthcare, housing,land, etc.
- Problems caused by government not being able to cater for the increase causing people to find their own solutions.
- This includes people seeking dangerous places to live because they a=have few choice. Marginal sites.
- Problems caused by government not being able to cater for the increase causing people to find their own solutions.
- Problems servicing healthcare, housing,land, etc.
- Effects of over population
- Demand for children's healthcare
- Cheap labour due to high competition for limited jobs available.
- People in richer countries benefit from this.
- Benefits from growth
- Opportunities for business to grow.
- However this can widen the gap between rich and poor.
- Opportunities for business to grow.
- Pressures on the land
- When growth stops.
- When people start to live longer than there will be a higher dependency rate for tax payers to pay for.
- It could lead to increasing job opportunities but also essential job that require skills may not be filled.
- Encouraging migrants is a solution to this problem.
- Usually in MEDC'S
- A trend in the UK is counter urbanisation - when people move out of big cities and to the countryside.
- This can have several effects.
- Effect 1 - When retiring people move to places this results in a higher demand for health care.
- Effect 2 - Planning in towns will have to cater for more people.
- This can have several effects.
- Another trend is retirement villages that are designed to cater for older people.
- Advantages - create secure environments and support for older people.
- Disadvantage - not everyone wants to be separated from their community.
- Some older people move to another country.
- Advantage - warmer weather, lower bills, new oppurtunities
- Disadvantage - different language/ laws/ health care. Also separation from family.
