AP Human Geography Unit 2 Review (Everything You Need To Know!)
Mr. Sinn・35 minutes read
The text discusses key concepts in AP Human Geography Unit 2, such as population distribution, density, composition, and factors impacting demographic metrics and migration patterns, including policies like China's one-child policy and the impact of economic opportunities on fertility rates and migration flows. The Ultimate Review Packet provides study materials like videos and practice quizzes to aid in understanding these concepts for the course exam.
Insights
- Population distribution is influenced by physical factors like climate and human factors such as economic opportunities, historical events, and political stability, impacting political power, voting patterns, economic opportunities, social services, and environmental sustainability.
- Demographic characteristics like age, gender, ethnicity, education, income, and occupation are analyzed through population pyramids, while metrics such as Total Fertility Rate (TFR), Infant Mortality Rate (IMR), and Natural Increase Rate (NIR) are indicators of population growth or decline, affected by social, cultural, economic, and political factors, as well as access to healthcare, education, and urbanization.

Recent questions
What factors influence population distribution?
Physical and human factors, historical events, and political stability affect population distribution. Settlement locations are determined by climate, economic opportunities, and other factors. The concentration of the human population is notably high in regions like South Asia, East Asia, Southeast Asia, and Europe. These regions attract people due to various reasons, shaping the distribution of populations across the globe.
How do population density types differ?
Population density types include arithmetic, physiological, and agricultural density, each measuring different aspects of population. Arithmetic density indicates how crowded an area is, physiological density measures pressure on the environment, and agricultural density reflects the efficiency of agricultural production. These metrics help in understanding the distribution of populations and the utilization of resources in different regions.
What impacts do population density and distribution have?
Population density and distribution have significant impacts on various aspects of society. They influence political power, voting patterns, economic opportunities, social services, and environmental sustainability. Understanding how populations are distributed and the density of these populations is crucial for policymakers, urban planners, and researchers to address issues related to infrastructure, resource allocation, and social welfare.
How do demographic characteristics affect population composition?
Population composition is influenced by demographic characteristics such as age, gender, ethnicity, education, income, and occupation. These factors are analyzed through population pyramids to understand the structure of a population. Changes in demographic characteristics can have profound effects on social dynamics, economic trends, and policy-making, shaping the future of societies and nations.
What are the key factors influencing population growth?
Population growth is influenced by factors such as birth rates, death rates, fertility rates, and migration patterns. The natural increase rate (NIR) is calculated by subtracting the crude death rate (CDR) from the crude birth rate (CBR). High NIR countries face challenges related to infrastructure and resource management due to rapid population growth. Additionally, access to healthcare, education, economic development, and political policies play crucial roles in shaping population growth trends globally.

Factors Affecting Population Growth and Decline
- CBR and CDR are used to calculate the natural increase rate (NIR), which shows population growth or decline by subtracting CDR from CBR.
- High NIR countries double their population faster, leading to challenges in infrastructure and resources.
- Total Fertility Rate (TFR) of 2.1 is considered replacement rate; below leads to population decrease, above indicates growth.
- Infant Mortality Rate (IMR) is deaths of infants under one year per 1000 live births.
- Social, cultural, economic, and political factors impact population metrics like TFR, IMR, and NIR.
- Access to better healthcare and education increases life expectancy, decreases TFR, IMR, and NIR.
- Economically developed areas see smaller family sizes due to urbanization and job shifts.
- Political policies influence population growth through laws, family planning promotion, and education access.
- Demographic Transition Model progresses through stages with changing birth and death rates, impacting population growth.
- Epidemiologic Transition Model correlates stages with causes of death, from infectious diseases to degenerative diseases.

Policies, Migration, and Urban Growth in Demographics
- Anti-natalist policies aim to reduce births in high NIR countries, like China's one-child policy.
- China has recently modified its one-child policy due to its effectiveness in limiting family size.
- Migration policies are influenced by economic needs, national security, and cultural values.
- Economic development and opportunities for women lead to lower fertility rates and infant mortality.
- Gender inequality affects birth rates, with less opportunity leading to higher TFR.
- Migration patterns are explained by Ravenstein's laws, influenced by economic reasons and undertaken by young adults.
- Migrants tend to settle in different towns before reaching larger urban areas.
- The gravity model explains migration flows based on population size and distance between origin and destination.
- Large urban areas experience population growth primarily through migration rather than natural birth.
- Forced migration occurs due to reasons like war, political oppression, or environmental disasters, leading to refugees or internally displaced persons.
