Key Lessons from "Leaving Certificate Geography Notes: Population" · What is Population? Population refers to the total number of people living in a specific area, influenced by factors like birth rates, death rates, and migration patterns. · Factors Affecting Population Growth: Population growth is shaped by natural increase (birth rate minus death rate) and migration. Economic development, healthcare, and cultural factors also play a key role. · Population Distribution and Density: Population distribution refers to how people are spread across a region, while density measures the number of people per square kilometer. These are influenced by physical factors like climate and resources, as well as social and economic factors. · Population Pyramids: Population pyramids visually represent a population’s age and gender structure, showing trends like aging populations or youthful populations. · Global Population Trends: Current trends include rapid growth in developing countries, aging populations in developed regions, and urbanization due to migration toward cities. |
Important Takeaways from "Leaving Certificate Geography Notes: Population" · Factors Influencing Population Growth: Income levels, society, and culture shape population growth. Developed countries often experience slower growth due to higher living standards, while developing nations see higher growth rates due to limited access to education and healthcare. · Causes and Effects of Overpopulation: Overpopulation occurs when resources cannot meet the demands of a growing population. In countries like Sudan, high birth rates and resource depletion lead to food shortages and environmental degradation, while urban areas like Brazil’s favelas face overcrowding and poor living conditions. · Population Structure and Development: The Demographic Transition Model illustrates how birth and death rates change with economic development. Countries progress through stages, from high birth and death rates in less developed regions to natural population decline in highly developed areas like Germany. · Population Density and Distribution: Population density varies by region and is influenced by factors like economic development and physical geography. Core regions like the Greater Dublin Area are densely populated and well-developed, while peripheral regions have sparse populations and slower development. · Global Trends and Challenges: Urbanization, resource pressure, and changing fertility rates highlight global population issues. Developing countries face challenges like high infant mortality, while developed nations deal with aging populations and workforce shortages. |
