Population & Demographics 1
Explain the significance of population density.
Population density shows how many people live in a given area. High density can strain resources, while low density may lead to underused resources and limited economic development.
Explain how the natural rate of increase is calculated.
The natural rate of increase is calculated by subtracting the death rate from the birth rate. It represents the growth or decline of a population without considering migration.
Explain how birth rates progress throughout stages 1-4 of the demographic transition model.
In stages 1 and 2, birth rates are high due to limited access to healthcare and education. In stage 3, birth rates begin to decline as access to family planning and education improve. In stage 4, birth rates stabilize at low levels, reflecting urbanization and economic development.
Explain the significance of push factors and identify at least 4.
Push factors drive people to leave their current location. Examples include military conflict, lack of jobs, religious persecution, and government restricting civil rights, as these create unsafe or unfulfilling living conditions.
Explain the primary difference between the structure of population pyramids for more developed countries and less developed countries.
Population pyramids in more developed countries typically have a narrow base and a broader top, indicating lower birth rates and aging populations. In less developed countries, the base is wider, showing higher birth rates and younger populations.
Explain what the natural rate of increase signifies about a country.
The natural rate of increase reflects a country’s population growth, showing the difference between birth and death rates. A higher rate indicates rapid population growth, while a lower rate suggests stable or declining population trends.
Explain how death rates progress throughout stages 1-4 of the demographic transition model.
In stage 1, death rates are high due to disease, famine, and lack of healthcare. In stage 2, death rates decline as sanitation and healthcare improve. In stage 3, death rates continue to fall with further advancements. In stage 4, death rates stabilize at low levels.
Explain the significance of pull factors and identify at least 4.
Pull factors attract people to a new location, often improving their quality of life. Examples include job opportunities, better healthcare, political stability, and higher living standards.
Explain the significance of population pyramids and identify the main pieces of information that they display.
Population pyramids show the age and gender distribution of a population, revealing trends in birth rates, life expectancy, and population growth. They help predict future demographic changes.
Identify factors that contribute to high birth rates and briefly explain the significance of this.
High birth rates are influenced by limited access to healthcare, education, and contraception, as well as cultural norms. In some regions, children contribute to the family’s economic survival, leading to larger families.
Explain how the natural rate of increase changes throughout stages 1-4 of the demographic transition model.
In Stage 1, the natural rate of increase is low or stable due to high birth and death rates. In Stage 2, it rises sharply as death rates fall. By Stage 3 and 4, the rate declines as birth rates decrease.
Explain the difference between visas and green cards.
Visas allow temporary entry for specific purposes, like tourism or work. Green cards grant permanent residency, allowing individuals to live and work in the country indefinitely.
Identify at least 2 things that would cause the world population to increase.
A sudden drop in the death rate due to medical advancements would increase population growth. Additionally, higher birth rates would also contribute to a population increase.
Identify factors that contribute to low birth rates and briefly explain the significance of this.
Low birth rates are often linked to access to education and family planning, which allow people to make informed choices about family size. When women have more opportunities, they tend to have fewer children.
Identify the social services that less developed countries would benefit from the most and explain the significance of this.
Less developed countries would benefit most from healthcare, education, and infrastructure services. These services improve quality of life, reduce poverty, and support sustainable development, helping these nations achieve stability and long-term growth.
Explain the significance of carrying capacity.
Carrying capacity refers to the maximum population size an environment can support based on available resources. Exceeding this capacity leads to resource depletion, environmental degradation, and potential population decline.
Explain the significance of life expectancy.
Life expectancy measures the average number of years people are expected to live. It reflects a country's overall health, healthcare quality, and living conditions, impacting planning for resources and services.
Explain the significance of population aging.
Population aging occurs when the proportion of elderly people increases, often due to lower birth rates and longer life expectancy. It can strain healthcare systems and impact economic productivity.
Identify the social services that more developed countries would benefit from the most and explain the significance of this.
More developed countries would benefit most from healthcare, social security, and mental health services. These services enhance overall well-being, address aging populations, and maintain a high quality of life for citizens across various age groups.
Explain the general relationship between birth rates and how developed a country is.
In more developed countries, birth rates are typically lower due to better access to healthcare, education, and family planning. In less developed countries, birth rates are higher due to limited access to these resources.
