Population and economic development patterns
Population and Economic Development Patterns
Population Patterns
- Population distribution refers to the spread of people across a given area.
- Different geographies have varying degrees of population density, which is the number of people per unit of land area.
- Factors like access to resources, the quality of soil for agriculture, climate conditions, and environmental hazards impact population distribution.
Physical and Human Factors Affecting Population Distribution
- Physical Factors: Topographical features such as mountains, deserts, rivers, and oceans can significantly impact population distribution.
- Climate and Weather: Areas with extreme weather conditions tend to have lower population densities.
- Soil Quality and Agriculture: Regions with fertile soil, crucial for agriculture, usually have higher population densities.
- Access to Water: Access to clean and reliable water sources often influences where people live.
Human Factors Affecting Population Distribution
- Political Stability: People tend to move away from areas with frequent conflicts or political instability.
- Economic Opportunities: Areas with more job prospects generally attract more people.
- Transport Infrastructure: Efficient transport systems allow for easier movement of people and goods, impacting population density.
Economic Development Patterns
- There's a distinct link between population distribution and economic development.
- Urban areas generally have higher economic development due to the availability of employment opportunities, infrastructure, and services.
- The primary sector, including farming, fishing, and mining, usually prevails in less populated areas.
- The secondary and tertiary sectors, encompassing manufacturing and services, generally develop more in urban, densely populated areas.
- Economic development can also be influenced by international forces such as globalisation and investment from transnational corporations.
Demographic Transition Model
- The Demographic Transition Model is a tool used to understand changes in population over time.
- It includes four stages: High Stationary, Early Expanding, Late Expanding and Low Stationary.
- This model helps in understanding how economic development can influence population growth rates.
Relationship Between Economic Development and Migration
- Economic opportunities can cause migration, where people move from one place to another for work.
- Push factors like poverty, unemployment, or conflict can cause people to leave their homes.
- On the other hand, pull factors, such as better living conditions, higher salaries, or societal peace, can attract individuals to new areas.
Impact of Migration on Economic Development
- In the short term, migration can lead to labour shortage in the area of origin but can solve labour surplus problems in the destination area.
- In the long term, remittances from migrants can lead to development and prosperity in the areas of origin.
- However, uncontrolled migration can lead to overpopulation, putting pressure on the resources and infrastructure in destination areas.
