“推拉理论”如何解释人口迁移？
How does “push-pull theory” explain migration?
推拉理论认为迁出地的不利因素（如贫困、战乱）把人“推”走，而迁入地的机会（如就业、自由）把人“拉”来，中间还受距离与政策的阻碍。它是最经典的迁移解释框架，但难以涵盖主观网络与文化因素。该理论至今仍广泛用于移民研究。
Push-pull theory holds that unfavorable conditions at the origin (poverty, war) “push” people out while opportunities at the destination (jobs, freedom) “pull” them in, mediated by distance and policy barriers. It is the classic framework for explaining migration, though it underplays subjective networks and culture. It remains widely used in migration studies.

“户籍制度”如何影响人口迁移？
How does the household registration system affect migration?
户籍制度将居民登记为农业或非农业户口，并绑定教育、医疗等公共资源，使跨地区迁移者常难平等享受服务。它在计划经济时期严格限制进城，后逐步放宽。改革户籍被视为促进公平流动的关键。
The household registration system classifies residents as agricultural or non-agricultural and ties public services like education and health to it, so cross-regional migrants often cannot access benefits equally. It strictly limited city entry in the planned-economy era and later eased. Reforming it is seen as key to fair mobility.

“人口转变理论”的后期阶段为何出现低生育？
Why does low fertility appear in the later stage of demographic transition theory?
随着城市化、女性教育和就业率提高、养育成本上升，家庭倾向于少生优生，生育率降至更替水平以下，即“第二次人口转变”。个人主义与晚婚也削弱了传统生育动机。这一阶段在许多发达国家已持续数十年。
With urbanization, higher female education and employment, and rising child-rearing costs, families prefer fewer, better-cared-for children, pushing fertility below replacement—the “second demographic transition.” Individualism and later marriage also weaken traditional motives to have children. This stage has persisted for decades in many developed countries.

“人口红利”指什么？
What does “demographic dividend” mean?
人口红利指劳动年龄人口占比高、抚养负担轻时，社会生产和储蓄能力增强，有利于经济增长。它通常不是自动发生的，需要足够的就业与教育配合。红利期过后往往迎来老龄化挑战。
The demographic dividend refers to a period when the working-age share is high and dependency burden is low, boosting production and savings and aiding growth. It does not happen automatically; it needs enough jobs and education. After the dividend passes, aging challenges often arrive.

什么是难民？它与经济移民有何不同？
What is a refugee, and how does it differ from an economic migrant?
难民是因战乱、迫害而有充分理由惧怕返回本国的人，受国际法保护并享有特定救助权利。经济移民则主要为改善生活而迁移，通常不受同等保护。区分二者关系到遣返与收容政策的合法性。
A refugee is someone with well-founded fear of persecution or war who cannot return home, protected by international law with specific rights. An economic migrant moves mainly to improve life and usually lacks that protection. The distinction matters for the legality of deportation and asylum policy.

“移民融入”包含哪些方面？
What does “migrant integration” involve?
移民融入指新移民在经济（就业）、社会（交往）、文化（语言价值）和政治（权利参与）等层面逐步被接收社会接纳的过程。融入顺畅能减少冲突并释放人口红利。语言教育与反歧视政策是关键手段。
Migrant integration is the process by which newcomers are accepted across economic (employment), social (interaction), cultural (language and values), and political (rights and participation) dimensions. Smooth integration reduces conflict and releases demographic dividends. Language education and anti-discrimination policy are key tools.

19世纪的“华工”主要去了哪里？
Where did 19th-century “Chinese laborers” mainly go?
鸦片战争后，大量华工以契约劳工身份前往东南亚、美洲和澳洲的矿山、铁路与种植园谋生。他们填补了殖民地开发的劳动力缺口，也常遭受歧视与严苛待遇。今天海外华人社区多源于此。
After the Opium Wars, large numbers of Chinese laborers went as contract workers to mines, railways, and plantations in Southeast Asia, the Americas, and Australia. They filled labor shortages in colonial development but often faced discrimination and harsh treatment. Many overseas Chinese communities today trace back to them.

“离散族群”是什么意思？
What does “diaspora” mean?
离散族群指因迁移、贸易或被迫离开故土，分散居住世界各地却仍保持共同文化认同的族群，如犹太离散、非洲离散。他们常维持与祖籍地的情感与经济联系。离散研究揭示了身份的多重性。
A diaspora is a group scattered across the world after migration, trade, or forced removal yet retaining a shared cultural identity, such as the Jewish or African diasporas. They often keep emotional and economic ties to the homeland. Diaspora studies reveal the multiplicity of identity.

爱尔兰大饥荒为何引发大规模移民？
Why did the Irish Famine trigger mass emigration?
1845年起马铃薯病害导致爱尔兰大饥荒，依赖单一主食的穷人大量饿死。幸存者为求生涌向美洲和英国，仅数十年间数百万人离开家园。它深刻改变了爱尔兰的人口结构并塑造了海外爱尔兰裔社群。
From 1845 a potato blight caused the Irish Famine, killing huge numbers of poor people who relied on that single staple. Survivors fled to the Americas and Britain, with millions leaving over just a few decades. It profoundly changed Ireland's population structure and shaped overseas Irish communities.

战后西德的「客籍劳工」（Gastarbeiter）计划怎样塑造了今天的移民结构？
How did West Germany's post-war 'guest worker' (Gastarbeiter) program shape today's migration structure?
1955 年起，西德与土耳其、意大利等国签订招募条约，引入被视为「临时」的客籍劳工填补工厂空缺。许多人最终定居并接来家人，使德国从「临时用工」转变为长期的多元移民社会。
From 1955 West Germany signed recruitment treaties with Turkey, Italy, and others to bring in 'guest workers' seen as temporary fillers of factory jobs. Many stayed and later reunited families, turning Germany from temporary labor import into a lasting, diverse immigration society.

黑死病对欧洲人口造成了多大冲击？
How hard did the Black Death hit Europe's population?
14世纪中期的黑死病在数年内夺走欧洲约三分之一到一半的人口。劳动力骤减推高了工资、削弱了封建农奴制，并间接催化了社会经济变迁。它是中世纪人口史的重大转折点。
The mid-14th-century Black Death killed roughly one-third to half of Europe's population within a few years. The sudden labor shortage raised wages, weakened feudal serfdom, and indirectly spurred socioeconomic change. It was a major turning point in medieval population history.

什么是总和生育率？
What is the total fertility rate?
总和生育率指一名女性按当前生育水平度过一生平均会生育的孩子数。通常2.1左右才能维持人口不增不减。低于这一水平，长期人口就会趋于萎缩。
The total fertility rate is the average number of children a woman would bear over her life at current rates. About 2.1 is needed to keep population stable. Below that, population tends to shrink in the long run.

“人口爆炸”一词描述的是什么现象？
What phenomenon does “population explosion” describe?
人口爆炸指20世纪某些地区死亡率快速下降而出生率仍高，导致人口在短期内急剧增长的状况。它曾引发对资源与粮食的忧虑，如“马尔萨斯恐慌”。随着教育普及与城市化，许多国家随后自然回落。
Population explosion describes a situation, especially in the 20th century, where death rates fell fast while birth rates stayed high, causing sharp short-term growth. It sparked fears about resources and food, such as “Malthusian panic.” As education and urbanization spread, many countries later fell back naturally.

横跨大西洋的「奴隶贸易」在几百年间把大约多少人从非洲送到了美洲？
Over centuries, about how many people did the transatlantic 'slave trade' carry from Africa to the Americas?
从 16 到 19 世纪，横跨大西洋的奴隶贸易把约「1200 万」非洲人强制运到美洲种植园做工，造成无数家庭破碎。联合国教科文组织将其列为人类共同记忆，提醒人们铭记这段历史。
From the 1500s to the 1800s, the transatlantic slave trade forcibly carried roughly 12 million Africans to work on American plantations, shattering countless families. UNESCO lists it as shared human memory, urging the world to remember.

什么是「人才外流」（brain drain），为什么有些国家会失去自己的专业人士？
What is 'brain drain,' and why do some countries lose their own professionals?
「人才外流」指受过高等教育或掌握技能的年轻人移居到收入更高的国家，导致原籍国损失医生、工程师等人才。世界银行指出，这对依赖「海外汇款」的国家既有损失，也常伴随资金与技能的回流。
'Brain drain' means highly educated or skilled people move to countries with higher pay, leaving their home country short of doctors, engineers, and the like. The World Bank notes that while it is a loss, such countries often also receive remittances and later skills flowing back.

什么是“迁徙自由”？
What is “freedom of movement”?
迁徙自由指公民在国内或国际间合法移动、选择居住地而不受不当限制的权利。许多国家宪法保障国内迁徙自由，但跨国流动仍受边境管控。它是个人发展机会的重要前提。
Freedom of movement is the right to move and choose residence, domestically or internationally, without undue restriction. Many constitutions guarantee internal movement, but cross-border mobility remains controlled by borders. It is an important precondition for individual opportunity.
