On the real AP exam, each SAQ part is worth 1 point — always be specific and include a causal mechanism when asked to explain.
SAQ Practice · define
Define crude birth rate (CBR).
Key Points for Full Credit
CBR = number of live births per 1,000 people per year
CDR = number of deaths per 1,000 people per year
Must define both with their specific components — not just say 'birth and death rates'
Rubric note: Award 1 point for a complete, accurate definition. CBR is the number of live births per 1,000 people in a population in a given year. Must include: (1) live births, (2) per 1,000 people, (3) per year. Saying 'how many babies are born' without the per-1,000 standardization is incomplete.
SAQ Practice · describe
Describe one push factor of migration.
Key Points for Full Credit
DTM Stage 1: high birth rate, high death rate → slow natural increase
Stage 2: death rate falls (improved sanitation/medicine), birth rate stays high → rapid population growth
Stage 3: birth rate falls → growth slows; Stage 4: both low → stable or declining population
Must describe the specific pattern for the stage named, not just list stage numbers
Rubric note: Award 1 point for a specific push factor with an explanation of how it drives people to leave. Push factors are conditions at the origin that repel people. Accept: war or conflict, political persecution, economic hardship, environmental disasters, famine, disease, discrimination. Must identify a specific factor AND describe why it causes people to leave — not just list it.
SAQ Practice · explain
Explain how pull factors influence migration patterns.
Key Points for Full Credit
A wide base = high birth rates, young population (developing countries)
A narrow base = low birth rates, aging population (developed countries)
Must explain what shape indicates — not just say 'it shows age and gender'
Rubric note: Award 1 point for explaining the causal mechanism. A complete response identifies pull factors (conditions at the destination that attract migrants) and explains how they shape where people choose to move. Must explain HOW the factor influences the decision, not just define pull factors.
SAQ Practice · describe
Describe one stage of the Demographic Transition Model.
Key Points for Full Credit
Describes a specific push factor: something that drives people to leave (poverty, conflict, environmental disaster, persecution)
OR a specific pull factor: something that attracts people (economic opportunity, political freedom, family reunification)
Must be specific — not just 'bad conditions' or 'better opportunities'
Rubric note: Award 1 point for accurately describing a specific stage with BOTH its birth rate and death rate characteristics. Must name the stage AND describe what happens to birth and death rates. Stage 1: high birth, high death. Stage 2: high birth, falling death, rapid growth. Stage 3: falling birth, low death. Stage 4: low birth, low death, stable or declining population.
SAQ Practice · explain
Explain how population growth affects resource use.
Key Points for Full Credit
Ravenstein's Laws: most migrants move short distances; migration occurs in waves/steps; urban areas attract more migrants than rural
OR: migrants moving long distances tend to go to major cities
Must describe a specific law with enough detail to demonstrate understanding
Rubric note: Award 1 point for explaining a causal relationship between population growth and resource use. Must explain that as population increases, demand for resources increases — and explain a specific consequence (resource depletion, environmental degradation, rising prices, conflict over scarce resources). Must go beyond 'more people use more resources.'
SAQ Practice · describe
Describe one type of forced migration.
Key Points for Full Credit
High population density does NOT necessarily mean overpopulation — depends on carrying capacity and resources
Overpopulation occurs when population exceeds the ability of the environment/economy to support it sustainably
Must explain the distinction — not just restate density figures
Rubric note: Award 1 point for naming a specific type of forced migration AND describing the conditions that make it forced. Accept: refugee migration (fleeing war or persecution); internally displaced persons; slave trade; environmental displacement; ethnic cleansing. Must explain what makes it forced — lack of choice.
SAQ Practice · explain
Explain how migration affects the economy of receiving areas.
Key Points for Full Credit
Remittances flow from immigrants back to origin countries, supporting families and local economies
Can represent a significant portion of GDP in some developing countries (e.g., Philippines, Mexico)
Must explain the directional flow and economic impact — not just define the word
Rubric note: Award 1 point for explaining a specific economic effect with a causal mechanism — e.g., immigrants fill labor shortages; immigrant entrepreneurs create businesses; migrant workers may compete with native workers affecting wages. Must explain HOW migration produces the economic effect.
SAQ Practice · describe
Describe one effect of aging populations.
Key Points for Full Credit
Describes a specific environmental consequence: deforestation, soil degradation, water scarcity, urban sprawl, increased pollution
Links it to population growth or density as the causal mechanism
Must describe mechanism — not just list an environmental problem
Rubric note: Award 1 point for a specific, accurate effect. Accept: increased healthcare and pension costs; labor force shrinkage slowing economic growth; higher dependency ratios; countries increasing immigration to maintain workforce levels. Must be specific — 'older populations need more care' is too vague.
SAQ Practice · explain
Explain how remittances impact origin countries.
Key Points for Full Credit
Explains a specific pro-natalist policy (incentives to increase birth rates: cash bonuses, parental leave, child subsidies) OR anti-natalist (discourage births: one-child policy, education, contraception access)
Identifies a real country example
Must describe the mechanism of the policy — not just name it
Rubric note: Award 1 point for explaining a causal mechanism connecting remittances to conditions in the origin country. A complete response identifies remittances (money sent by migrants to family) and explains a specific impact — e.g., providing foreign currency supporting household consumption; funding education or small businesses; in some countries exceeding foreign aid. Must explain the mechanism.
SAQ Practice · describe
Describe one reason migration policies create political conflict.
Key Points for Full Credit
Brain drain = emigration of highly educated/skilled workers from developing to developed countries
Hurts origin country by reducing human capital; benefits destination country's economy
Must explain the directional flow and consequences for both countries
Rubric note: Award 1 point for a specific reason. Accept: economic competition — native workers fear migrants taking jobs or lowering wages; cultural conflict — rapid demographic change produces nativist backlash; security concerns; humanitarian vs. sovereignty tension. Must be specific, not just 'people disagree about immigration.'
