1. Question 1: Define and Distinguish Natural Increase and Net Migration | 第1题：定义并区分自然增长与净迁移
Natural increase is the difference between the crude birth rate (CBR) and the crude death rate (CDR) in a population, usually expressed per 1000 people per year. It shows whether a population is growing or declining due to births and deaths alone, excluding migration effects. A positive natural increase means births exceed deaths; a negative figure indicates more deaths than births.
自然增长是指粗出生率（CBR）与粗死亡率（CDR）之间的差值，通常用每千人每年的数值表示。它仅反映人口因出生和死亡而产生的增减，不包括迁移的影响。正自然增长表示出生人数超过死亡人数，负值则表示死亡人数多于出生人数。
Net migration is the balance between immigration (in-migration) and emigration (out-migration). It is also often expressed as a rate per 1000 people per year. Unlike natural increase, net migration captures the movement of people across administrative or international boundaries. A positive net migration adds people to the area; a negative net migration results in population loss through movement.
净迁移是指迁入（immigration）与迁出（emigration）之间的差额，通常也以每千人每年的比率表示。与自然增长不同，净迁移衡量的是人口跨越行政或国际边界的流动。净迁移为正表示人口因迁移而增加，净迁移为负则表示人口因迁移而减少。
In mark schemes, examiners look for precise definitions, use of technical vocabulary, and a clear contrast between the two concepts. A common mistake is to describe net migration simply as ‘people moving’ without specifying the balance, or to confuse net migration with gross migration flows. Always pair definitions with units (per 1000 or ‰) where appropriate.
在评分标准中，考官看重准确的定义、术语的使用，以及两个概念的明确区分。常见的错误是把净迁移简单说成“人口移动”而不说明差额，或者将净迁移与总迁移流量混淆。记得在适当的时候为定义配上单位（每千人或者‰）。
2. Question 2: Describe the Demographic Transition Model (DTM) | 第2题：描述人口转型模型（DTM）
The DTM illustrates how a country’s birth and death rates change as it develops. In Stage 1 (high fluctuating), both rates are high and variable, so natural increase is low and population grows very slowly. Stage 2 (early expanding) sees death rates fall sharply due to improved healthcare and sanitation, while birth rates remain high, resulting in rapid population growth. Stage 3 (late expanding) shows birth rates beginning to decline because of social changes, such as increased female education and access to contraception; population growth starts to slow. Stage 4 (low fluctuating) is characterised by low birth and death rates, leading to a stable or very slowly growing population. Some versions add Stage 5, where birth rates drop below death rates, causing natural decrease.
DTM 展示了随着国家的发展，其出生率和死亡率如何变化。第一阶段（高位波动）：出生率和死亡率都很高且波动大，自然增长很低，人口增长缓慢。第二阶段（早期扩张）：由于医疗和卫生条件的改善，死亡率急剧下降，而出生率仍维持高位，造成人口快速增长。第三阶段（晚期扩张）：出生率开始因社会变化（如女性教育提升和避孕普及）而下降，人口增长速度放缓。第四阶段（低位波动）：出生率和死亡率都处于低水平，人口稳定或极其缓慢地增长。有的版本会加上第五阶段，即出生率降到死亡率以下，产生人口自然减少。
To gain full marks, you must go beyond simply naming the stages. Use data‑like descriptions, mention typical examples (e.g., UK in Stage 4, Niger in Stage 2), and link each stage to one or two specific reasons for rate changes. Avoid treating the model as deterministic; mention that not all countries follow the path identically.
要想拿到满分，仅列出各阶段名称是不够的。要使用数据式的描述，举出典型例子（如英国处于第四阶段，尼日尔处于第二阶段），并将每个阶段的变化与一两个具体原因联系起来。避免将模型视为绝对规律；可以提到并非所有国家都完全遵循这一路径。
3. Question 3: Analyse a Population Pyramid | 第3题：分析人口金字塔
When given a population pyramid, begin by describing the overall shape: a wide base indicates a high birth rate and a youthful population; a narrow base suggests a low birth rate. A pyramid with straight sides and a wider middle implies low death rates across most age groups and an ageing population. Mention the dependency ratio by identifying the proportions of young dependents (0‑14) and old dependents (65+). Annotate any anomalies, such as a bulge caused by migration or a past baby boom.
分析人口金字塔时，首先要描述整体形状：底部宽表示高出生率和年轻型人口，底部窄则表示低出生率。金字塔侧边较直、中间较宽意味着大多数年龄组死亡率低，人口老龄化。通过辨别少儿抚养比（0‑14岁）和老年抚养比（65岁以上）来提及抚养比。标注任何异常，如迁移造成的凸起或过去的婴儿潮。
Next, infer the stage of the DTM the country is in. A wide‑base pyramid suggests Stage 2; a narrowing base with a larger working‑age group suggests Stage 3; and a more rectangular shape points to Stage 4 or 5. Always support interpretations with features from the pyramid, such as the percentage of population in each cohort. Common pitfalls include over‑generalising or failing to read the exact age‑sex percentages provided.
然后，推断该国处于 DTM 的哪个阶段。底部宽的金字塔指向第二阶段；底部开始变窄、劳动年龄人口较多的指向第三阶段；较均匀的矩形形状指向第四或第五阶段。所有解读都要用金字塔上的特征来支撑，例如各年龄组的百分比。常见失误包括过度概括，或没有利用题目给出的具体年龄‑性别百分比。
4. Question 4: Explain Push‑Pull Factors in Rural‑Urban Migration | 第4题：解释城乡迁移中的推拉因素
Push factors are negative conditions in rural areas that force people to leave. They include limited job opportunities, low wages in agriculture, poor access to education and healthcare, and environmental hazards such as drought. Pull factors are the perceived advantages of urban areas that attract migrants: better employment prospects, higher income, access to services, and the excitement of city life. Lee’s model emphasises that migration decisions are also influenced by intervening obstacles, such as distance or cost, and personal factors.
推力因素是指农村地区迫使人口离开的负面条件，包括就业机会有限、农业工资低、教育和医疗资源匮乏、以及干旱等环境灾害。拉力因素是城市地区吸引移民的预期优势：更好的就业前景、较高收入、服务设施完善，以及都市生活的吸引力。Lee 的模型强调，迁移决策还会受到介入障碍（如距离或迁移成本）以及个人因素的影响。
For a strong answer, you must provide specific, located examples. For instance, rural‑urban migration in India is driven by push factors like monsoon failure and land fragmentation, while cities such as Mumbai offer pull factors like textile factory jobs. Examiners penalise vague statements. Use connectives like ‘this leads to’ to show causation and always tie factors to the flow of people.
高分答案必须提供具体的、有地点的例子。例如，印度农村向城市迁移的推力因素包括季风失败和土地碎片化，而孟买等城市提供纺织厂工作等拉力因素。考官会扣减笼统表述的分数。使用“这导致……”之类的连接词来展示因果关系，并始终将因素与人口流动联系起来。
5. Question 5: Evaluate the Impacts of International Labour Migration on Source and Destination Areas | 第5题：评估国际劳工迁移对来源地和目的地的利弊
For source areas, positive impacts include remittances, which boost local economies and reduce poverty, and reduced pressure on local resources and jobs. However, negative impacts involve the loss of young, economically active workers, leading to a skewed age structure, broken families, and a potential ‘brain drain’ if skilled workers leave permanently. For destination areas, benefits are a ready supply of labour for low‑paid sectors, cultural diversity, and contributions to tax and social security systems. Drawbacks may include social tensions, overcrowding, and pressure on housing and public services.
对来源地而言，积极影响包括汇款（这些汇款能提振当地经济、减少贫困），以及缓解当地资源和就业压力。但消极影响包括年轻劳动力流失，导致年龄结构失衡、家庭分离，如果技术工人永久离开还可能产生“人才外流”。对目的地而言，好处是获得低薪行业所需的劳动力、增加文化多样性，以及对税收和社保体系的贡献。弊端则可能包括社会矛盾、过度拥挤，以及给住房和公共服务带来压力。
When evaluating, you should weigh the scale of these impacts and refer to a specific case study, such as Mexican migration to the USA or Polish migration to the UK. Use data to support your points — for example, remittances to Mexico reached over $50 billion in one recent year. A balance of both positive and negative, plus a conclusion on whether the overall effect for each area is beneficial, is needed for Level 3 + marks.
评估时，需要权衡影响的规模，并引用具体案例，例如墨西哥向美国的迁移或波兰向英国的迁移。用数据支撑论点——例如，墨西哥在某一近年获得的汇款超过500亿美元。要兼顾积极和消极两方面，并在结论中评判对每个地区总体影响是否有利，方可拿到3级及以上的分数。
6. Question 6: Assess the Effectiveness of China’s One‑Child Policy | 第6题：评估中国计划生育政策的有效性
China introduced the policy in 1979 to curb rapid population growth. It succeeded in reducing fertility — the total fertility rate fell from about 5.7 to around 1.6 by the 2000s. This slowed population growth and eased pressure on resources, contributing to economic growth. However, the policy also led to a distorted sex ratio, an ageing population, and a shrinking workforce. Enforcement methods such as fines and forced abortions raised ethical concerns.
中国于1979年实施计划生育政策以遏制人口快速增长。该政策成功降低了生育率——总和生育率从约5.7降至2000年代的大约1.6。这放慢了人口增长速度，缓解了资源压力，为经济增长作出贡献。但该政策也造成性别比失衡、人口老龄化和劳动力萎缩。罚款、强制堕胎等执法手段引发了伦理争议。
In an AS exam, you need to demonstrate balance. Use precise statistics and name specific consequences, such as the ‘4‑2‑1 problem’ where one child supports two parents and four grandparents. Assess effectiveness not just by birth reduction, but also by social cost. Conclude with a clear judgement, for example, that the policy was numerically successful but socially problematic, and discuss how the shift to a two‑child policy acknowledged these issues.
在 AS 考试中，你需要展示平衡的论述。使用精确的统计数字，并列出具体后果，例如“4‑2‑1问题”（一个孩子需要赡养两位父母和四位祖父母）。评估有效性不能只看出生减少，还要考虑社会代价。最后给出明确的判断，例如该政策在数字上是成功的，但在社会层面带来了问题，并讨论转向二孩政策如何承认了这些问题。
7. Question 7: Discuss the Challenges of an Ageing Population in the UK | 第7题：讨论英国人口老龄化带来的挑战
The UK’s elderly dependency ratio is rising as life expectancy increases and fertility remains below replacement level. This puts enormous pressure on the pension system — a growing retired population must be supported by a shrinking working‑age group. The state pension age has been raised to reduce costs, but this can be politically unpopular. Healthcare demands also escalate, with a higher incidence of chronic diseases such as dementia and arthritis requiring more long‑term care facilities and NHS funding.
随着预期寿命延长以及生育率低于更替水平，英国的老年抚养比正不断上升。这给养老金体系带来了巨大压力——不断增加的退休人员需要由正在缩减的劳动年龄人口来供养。政府已提高领取国家养老金的年龄以削减开支，但这在政治上可能不受欢迎。医疗保健需求也在升级，痴呆症、关节炎等慢性病发病率上升，需要更多长期护理设施和 NHS 资金。
Other challenges include a smaller tax base, labour shortages in certain sectors, and increased need for age‑friendly housing and transport. Solutions involve immigration of younger workers, encouraging later retirement, and promoting private pensions. In your answer, link each challenge to a specific policy response and show understanding of the spatial variation — for example, coastal retirement towns face more acute pressures than youthful cities.
其他挑战包括税基缩小、某些行业的劳动力短缺，以及对适老型住房和交通的需求增加。应对方案包括吸引年轻移民、鼓励延迟退休、以及推广私人养老金。作答时，需将每项挑战与具体的政策回应联系起来，并体现出对空间差异的理解——例如，沿海退休城镇面临的压力比年轻化城市更为严峻。
8. Question 8: Interpret a Birth and Death Rate Graph | 第8题：解读出生率与死亡率数据图
When presented with a line graph showing crude birth rate and death rate over time, start by stating the overall trend: ‘Both birth rate and death rate have declined over the period, but death rate fell first and more steeply.’ Identify key turning points using years and data from the axes. For example, ‘In 1950, CBR was 42‰ while CDR was 28‰; by 2020, CBR had fallen to 18‰ and CDR to 8‰.’ This provides evidence for the DTM transition.
当给出显示粗出生率和粗死亡率随时间变化的折线图时，先陈述总体趋势：“出生率和死亡率均有所下降，但死亡率下降得更早、更快。”利用年份和坐标轴数据找出关键转折点。例如，“1950年出生率42‰，死亡率28‰；到2020年，出生率降至18‰，死亡率降至8‰。”这为 DTM 的过渡提供了证据。
Explain the gap between the two lines — the natural increase rate. A widening gap indicates rapid population growth (Stage 2), while a narrowing gap shows slowing growth (Stage 3). Now add reasons: CDR fell due to vaccination programmes, improved water supply, and better nutrition; CBR later fell because of family planning, urbanisation, and women’s education. Tie these reasons to the specific place shown in the graph, rather than giving generic factors, to score highly.
解释两条线之间的间距——即自然增长率。间距扩大表明人口快速增长（第二阶段），间距缩小则表明增长放缓（第三阶段）。然后添加原因：死亡率因疫苗接种计划、供水改善和营养提升而下降；之后出生率因计划生育、城市化以及女性受教育而下降。将这些原因与图表中所示的具体地点联系起来，而不是给出一堆泛泛的因素，这样才能拿到高分。
9. Question 9: Compare Population Structures of an MEDC and an LEDC | 第9题：比较一个发达国家与一个欠发达国家的人口结构
To compare, choose two contrasting countries, e.g. Japan and Uganda. Describe the shape of their population pyramids: Japan has a narrow base and a relatively wide top, indicating an ageing population with low birth and death rates. Uganda has a classic wide base that rapidly narrows, showing high birth rates but also relatively high mortality at older ages. Using percentages, note that over 25% of Uganda’s population is under 15, compared with about 12% in Japan, while Japan has over 28% aged 65+ , compared with under 3% in Uganda.
比较时，选择两个形成鲜明对比的国家，例如日本和乌干达。描述各自人口金字塔的形状：日本底部窄、顶部相对较宽，表明低出生率、低死亡率下的老龄化人口。乌干达则呈现典型的宽底部且迅速收窄的形状，说明高出生率，但中老年死亡率仍较高。利用百分比，指出乌干达有超过25%的人口在15岁以下，而日本这一比例约为12%；日本65岁以上人口超过28%，乌干达则不到3%。
Explain the socio‑economic implications. In Japan, a shrinking workforce funds the pension system, leading to policies encouraging immigration and robotics. In Uganda, a youthful population creates potential for a demographic dividend, but only if sufficient investment in education and jobs occurs; otherwise, it risks high unemployment. Explicit comparison words (‘whereas’, ‘in contrast’) and diagrams from your data response are vital.
解释社会经济影响。在日本，劳动力萎缩给养老金系统带来压力，促使政府推出鼓励移民和机器人技术的政策。在乌干达，年轻人口创造了人口红利潜力，但前提是需要在教育和就业方面进行充分投资；否则将面临高失业风险。明确使用比较词汇（“然而”、“相比之下”），并结合你的数据作答。
10. Question 10: Explain the Concept of Forced Migration with Reference to a Specific Example | 第10题：结合具体例子解释强迫迁移的概念
Forced migration occurs when people have no choice but to leave their homes due to conflict, persecution, environmental disaster, or development projects. Unlike voluntary migrants, they face immediate physical danger or serious human rights violations if they stay. Around 100 million people were forcibly displaced globally in recent years, including refugees and internally displaced persons (IDPs).
强迫迁移发生在我们别无选择，必须因冲突、迫害、自然灾害或发展项目而离开家园的时候。与自愿迁移者不同，强迫迁移者若留下将面临直接的人身危险或严重的人权侵犯。近年来，全球约有1亿人被迫流离失所，包括难民和境内流离失所者（IDP）。
A poignant example is the Syrian refugee crisis. Since 2011, civil war has driven over 6.8 million Syrians to flee the country, mostly to neighbouring Turkey, Lebanon, and Jordan, with many others seeking asylum in Europe. Push factors include bombing of civilian areas, lack of food and water, and torture. The massive influx has created pressure on host nations’ resources, but also highlighted international protection laws. Structure your response by defining the term, presenting the case study with statistics, and then examining both the causes and the consequences for origin and destination regions.
一个深刻例子是叙利亚难民危机。自2011年起，内战已迫使超过680万叙利亚人逃离家园，主要前往邻国土耳其、黎巴嫩和约旦，另有大量人口赴欧洲寻求庇护。推力因素包括对平民区的轰炸、食物和水短缺、以及酷刑。大规模涌入给接收国的资源带来了压力，但也凸显了国际保护法。作答时，先定义术语，再用统计数字展示案例，最后分析对来源地和目的地的原因与后果。
11. Key Command Words and How to Tackle Them | 第11题：关键指令词及其应对策略
In WJEC unit tests, command words determine the depth expected. ‘Define’ requires a precise meaning, often with an example. ‘Describe’ asks for trends, patterns, or characteristics from data. ‘Explain’ demands reasons and causal links. ‘Assess’ or ‘Evaluate’ involves weighing both sides and making a judgement. Many students lose marks by only giving descriptive content where explanation or evaluation is required.
WJEC 单元测试中，指令词决定了答题深度要求。“Define”（定义）需要给出准确含义，常配以例子。“Describe”（描述）要求写出数据中的趋势、模式或特征。“Explain”（解释）必须给出原因和因果联系。“Assess” 或 “Evaluate”（评估）需要权衡正反两面并作出判断。许多学生失分，是因为在需要解释或评估的地方只给出描述性的内容。
Before starting any answer, highlight the command word and any specific content words. For a 6‑mark ‘Explain’ question, you should aim for three clear, well‑developed reasons, each linked back to the question. For ‘Evaluate’, use a mini‑conclusion that starts with ‘Overall, …’ and includes both strengths and limitations. Practice differentiating between ‘Describe the trend’ and ‘Explain the trend’ with the same graph to build confidence.
在开始任何答案之前，用荧光笔标出指令词和具体的内容词。对于一道6分的“解释”题，你应写出三个清晰、展开的理由，每个理由都要紧扣题目。回答“评估”题，要用一个以“总体而言……”开头的微结论，并兼顾优点与局限。可以练习用同一张图表区分“描述趋势”和“解释趋势”，以增加把握。
12. Examiner Tips for Top Marks | 第12题：考官高分建议
Use geographical terminology throughout your responses: words like ‘natural increase’, ‘dependency ratio’, ‘intervening obstacles’, and ‘demographic dividend’ show precise understanding. Link ideas with connectives such as ‘this results in’, ‘consequently’, and ‘the impact of this is’. Every data response question requires you to quote figures from the resource. Never say ‘it is high’ without a number. Similarly, case study responses must include place‑specific detail — at least three well‑remembered facts from a named location.
答题全程都要使用地理术语：诸如“自然增长”、“抚养比”、“介入障碍”和“人口红利”等词语能体现准确的理解。用“这导致”、“因此”、“其影响是”等连接词串联观点。每一道数据分析题都需要你引用资源中的数字，切勿只说“它很高”而没有数据。同样，案例分析题必须包含地点专属的细节——至少三条从具体地点记住的可靠事实。
Time management is critical. A typical unit test has about 60 marks in 75 minutes, awarding roughly 1.2 marks per minute. For a 4‑mark question, spend no more than 5 minutes. Leave enough time for the 8‑ and 10‑mark extended writing questions, which carry the most weight. Always check the mark allocation to decide how many points to make. Finally, annotate diagrams and graphs quickly — this helps you pick out the key evidence under pressure.
时间管理至关重要。一份典型单元测试约有60分，时间75分钟，大约每分钟应得1.2分。对于4分题，至多花5分钟。要为8分和10分的扩展写作题留足时间，这些题目分值最高。始终参考分值决定应写多少个要点。最后，快速在图表和数据图上做标注——这有助于你在压力下提取关键证据。
