The word **住户 (zhùhù)** is a compound noun formed by combining the character **住 (zhù)**, meaning "to reside" or "live," with the character **户 (hù)**, meaning "household" or "door." This formation follows a common Chinese word-construction pattern where a verb (住) modifies a noun (户) to create a new, specific noun. Semantically, it blends the action of dwelling with the unit of a household, resulting in a term that collectively refers to the "residents" or "occupants" (i.e., the households living in a place), effectively meaning "inhabitant" or "tenant household."
