Understanding 人口 (rénkǒu)
The word 人口 literally combines 'person' (人) and 'mouth' (口), but it is used to mean 'population' — the number of people living in a certain area. It is a common term in discussions about demographics, urban planning, and social statistics.
Usage Notes
人口 is typically used to refer to the total number of people in a city, country, or region. It often appears in news reports, government statistics, and academic contexts. When talking about population growth or decline, 人口 is the standard term.
Common Collocations
- 人口增长 (rénkǒu zēngzhǎng): population growth — used when the number of people increases.
- 人口减少 (rénkǒu jiǎnshǎo): population decrease — used when the number of people declines.
- 人口密度 (rénkǒu mìdù): population density — refers to how many people live per unit area.
Important Distinctions
Do not confuse 人口 with 人数 (rénshù), which also means 'number of people' but is more general and can refer to counts in any context (like attendance). 人口 specifically refers to population in a demographic sense.
Practical Tip
When using 人口 in conversation, it often appears with verbs like 增加 (increase), 减少 (decrease), or 统计 (to count/statistics). For example, you might say “这个地区的人口正在增加” to describe a growing population.
