Question 1: Urbanization: The process by which increasing numbers of people live in cities and suburbs. Provide an example of urbanization in the US.

Answer: The growth of cities like New York and Los Angeles due to migration and economic opportunities.

Question 2: Population density: The number of people living per unit area, often expressed as persons per square kilometer. Why is this concept important?

Answer: It helps to understand how crowded an area is and aids in resource and infrastructure planning.

Question 3: Migration: The movement of people from one place to another. Name two types of migration relevant to US population changes.

Answer: Internal migration and international migration.

Question 4: Suburbanization: The process of population moving from city centers to suburbs. How has suburbanization affected US cities?

Answer: It has led to urban sprawl, increased demand for infrastructure, and changes in land use.

Question 5: Demographic transition: The shift in population growth rates through stages of development. Briefly describe its relevance to US population trends.

Answer: It explains declining birth rates and aging populations as the US develops economically.

Question 1: Which US city is known as the most densely populated urban area?

Answer: New York City

Question 2: Name three states in the US with low population density.

Answer: Alaska, Nevada, Wyoming

Question 3: What is the primary factor influencing population growth in the Southern US?

Answer: Climate and economic opportunities

Question 4: Explain the concept of 'urban sprawl' and its impact on the environment.

Answer: Urban sprawl refers to the uncontrolled expansion of urban areas into rural land, leading to habitat loss, increased pollution, and higher infrastructure costs.

Question 5: Identify two US regions with the highest population growth in recent decades.

Answer: The Sun Belt region and parts of the South, including Texas and Florida.

Question 1: The rapid growth of Austin, Texas, has been driven by economic development and climate. What are two challenges this urban growth presents?

Answer: Increased traffic congestion and strain on public services.

Question 2: Based on the case study, how does migration influence population distribution in Texas?

Answer: Migration from other US states and countries increases population in Texas, leading to urban expansion and demographic shifts.

Question 3: Identify one environmental concern associated with the population growth in Austin.

Answer: Increased air and water pollution due to urban development.

Question 4: Suggest one policy measure that could help manage the impacts of population growth in Austin.

Answer: Implementing sustainable urban planning and investing in public transportation.

Question 1: Analyse the causes of higher population densities along the US East Coast.

Answer: The East Coast has historically been a hub for economic opportunities, urbanization, favorable climate, and access to ports and transportation networks, attracting more people and leading to higher population densities.

Question 2: Explain why desert regions in the southwestern US have low population densities.

Answer: Desert regions like Nevada and Arizona have harsh climates, limited water resources, and fewer economic opportunities, which discourage large-scale settlement.

Question 3: Analyse the impact of climate on population distribution in the US.

Answer: Favorable climates attract settlement, as seen in the southern states with mild winters, while extreme cold or arid conditions limit population in northern and southwestern regions.

Question 1: To what extent have urban planning policies been successful in managing urban sprawl in US cities like Los Angeles and Houston? Consider social, environmental, and economic factors in your answer.

Answer: Urban planning policies such as zoning, development restrictions, and investment in public transportation have helped to contain urban sprawl in some areas, reducing environmental degradation and traffic congestion. However, challenges remain due to population growth and demand for housing, leading to continued expansion in suburban and exurban areas. The success varies by city, with some implementing more sustainable strategies than others, ultimately influencing the quality of urban life and environmental sustainability.

Question 2: Evaluate the effectiveness of policies aimed at encouraging population redistribution to less populated regions such as the Midwest or rural areas.

Answer: Policies such as tax incentives, infrastructure development, and investment in local amenities aim to attract residents to less populated regions. While some success has been achieved, challenges include limited economic opportunities, access to services, and existing infrastructure deficits. Overall, these policies have had mixed results, with some areas experiencing growth but many still facing depopulation and economic decline, indicating that a multifaceted approach is necessary for effective redistribution.
