1. Population and Settlement | 人口与聚落
Birth rate – the number of live births per 1,000 people per year. It is one of the key indicators of natural population change.
出生率 – 每年每千人的活产婴儿数。它是衡量自然人口变化的关键指标之一。
Death rate – the number of deaths per 1,000 people per year. A low death rate often indicates good healthcare and sanitation.
死亡率 – 每年每千人的死亡人数。低死亡率通常表明医疗和卫生条件良好。
Natural increase – the difference between birth rate and death rate, expressed as a percentage. It does not include migration.
自然增长率 – 出生率与死亡率之差，以百分比表示。它不包含人口迁移。
Population density – the number of people living per square kilometre. Densely populated areas include cities; sparsely populated areas include deserts and mountains.
人口密度 – 每平方公里居住的人数。人口稠密地区包括城市；人口稀疏地区包括沙漠和山区。
Urbanisation – the increase in the proportion of people living in towns and cities. It is driven by rural-to-urban migration and natural increase in urban areas.
城市化 – 城镇和城市人口比例的增加。它由农村向城市的人口迁移和城市地区的自然增长共同推动。
Mega-city – a city with a population of more than 10 million people. Examples include Tokyo, Delhi and Shanghai.
巨型城市 – 人口超过一千万的城市。例如东京、德里和上海。
- Memory trick: Think of B–D = NI (Birth minus Death equals Natural Increase). Remember that ‘density’ is about how crowded a place feels.
- 记忆窍门： 联想 B–D = NI（出生减死亡等于自然增长）。记住“密度”就是感受一个地方有多拥挤。
2. Migration | 人口迁移
Migration – the movement of people from one place to another with the intention of settling temporarily or permanently. It can be internal (within a country) or international.
