About 1.8 million people live in Montevideo’s urban area today, so the closest option among 3 million, 4 million, 1 million, and 7 million is 1 million (it slightly underestimates, but the others are much too high).

Current population snapshot

  • Recent demographic estimates put the Montevideo urban area at around 1.79–1.80 million inhabitants in 2025–2026.
  • The city proper (administrative city) is often quoted at about 1.3 million residents, which is likely what multiple‑choice questions round down to “1 million.”

Why not 3M, 4M, or 7M?

  • Uruguay’s entire national population is only about 3.5 million, so Montevideo alone cannot have 3 million, 4 million, or 7 million inhabitants.
  • Montevideo does hold roughly one‑third to one‑half of Uruguay’s population, which matches the 1.3–1.8 million range rather than the higher answer options.

Quick quiz-style answer

If this is a multiple‑choice question like those seen in school or forum homework threads, “1 million” is the intended correct choice, even though the more precise modern figure is closer to 1.8 million people.
