人口

1. Origins, structure, and basic meaning

• Structure: 人口 (じんこう) is a noun for the population, the total number of people living in a country, town, or other area.
• Basic usage: It is used for stating a town's population or showing population figures by region in a table.
  • この町の人口は約三万人だ。 — This town has a population of about thirty thousand.
  • 地図の横に地域ごとの人口を示す表がある。 — A table beside the map shows population by region.

2. Common pitfalls and similar expressions

• People and their total number
  • 人口 refers to the number of people in an area, not to one individual. 地域ごとの人口 divides that population figure by region.
