What is population density?
Population density refers to the number of people per square kilometer.
What does high population density imply?
High population density implies that there is a large number of people per square kilometer.
What are some impacts of high population density?
High population density can cause overcrowding, overwhelmed healthcare and education services, and increased use of transportation.
What are the environmental impacts of high population density?
• Increased pollution (vehicles and power consumption causing poor air quality)
• Deforestation (more land used for construction of apartments and establishments)
• Animal decline (threatened by overdevelopment and habitat destruction)
What are some solutions to high population density?
• Alternative forms of transportation (e.g., bicycles, public transportation services)
• Upgrade public spaces (planting trees for a green environment)
• Involve local community in planning
How does demography assist governments and policymakers?
Demography helps with resource allocation by analyzing patterns of aging, population growth/decline, and fertility rates.
What social issues can demography help identify?
Demography can identify social problems by highlighting disparities and inequalities within society.
What areas can benefit from planning based on demographic data?
Transportation systems, healthcare facilities, and school capacities can benefit from planning based on demographic data.
What are some solutions to high population density?
• Alternative forms of transportation (e.g., bicycles, public transportation services)
• Upgrade public spaces (planting trees for a green environment)
• Involve local community in planning
What factors influence life expectancy according to the graph?
Factors influencing life expectancy include access to resources, education, healthcare, and job opportunities. These elements contribute to overall well-being and longevity.
How does access to resources affect life expectancy?
Access to resources such as nutritious food, clean water, and safe housing can significantly improve life expectancy. These resources help maintain good health and prevent diseases.
What is meant by an aging population?
An aging population refers to a demographic shift where a larger proportion of the population is elderly. This can result from various social and economic factors.
What are the main causes of an aging population as mentioned in the text?
The main causes of an aging population are low birth rates and low death rates. These factors lead to a higher proportion of older individuals in the population.
Why might low birth rates contribute to an aging population?
Low birth rates contribute to an aging population because fewer young people are being born to balance the number of elderly individuals. This shifts the age distribution towards older age groups.
How do low death rates impact the demographic shift towards an aging population?
Low death rates impact the demographic shift towards an aging population by allowing more people to live longer. Advances in healthcare and living conditions reduce mortality rates, especially among the elderly.
