The city with the largest population in the world right now is Jakarta, Indonesia , when measured by its full urban area.

Clarifying the question

Your prompt says: “which of the following cities has the largest population?” but it does not list the specific options. To answer in a way that matches how this is discussed in recent data:

  • A 2025 UN‑linked analysis reported that Jakarta has overtaken Tokyo as the world’s most populous city , using an updated urban‑area method.
  • That method estimates Jakarta’s urban area at around 42 million people , putting it ahead of other mega‑cities like Tokyo, Delhi, and Shanghai.

So, if your multiple‑choice list includes Jakarta, Tokyo, Delhi, or Shanghai , the correct choice for “largest population” (in current global discussions and latest news) is Jakarta.

Why some sources still say Tokyo

You may still see many tables or quizzes saying Tokyo is the largest city:

  • Traditional rankings (like many population tables updated in early 2026) still list Tokyo’s metro area at about 37 million , ahead of Delhi and Shanghai.
  • Those rankings are based on older or different definitions of “urban area” or “metro area,” which is why there is a shift in newer reports that put Jakarta first.

In a typical exam or quiz written before this newer UN‑style update, Tokyo would often be marked as correct.

How to choose the answer in your quiz

Without seeing your exact options, here is a practical rule:

  • If Jakarta is among the options → pick Jakarta as having the largest population (using the latest urban‑area assessments).
  • If Jakarta is not listed but Tokyo is → pick Tokyo , since it is still widely cited as the biggest metropolitan area in many current tables and educational materials.

In short: with the very latest “trending” population discussions, Jakarta has just taken the top spot from Tokyo.

TL;DR:
Globally, using the newest urban‑area estimates, Jakarta is now considered the city with the largest population; if your options don’t include Jakarta, choose Tokyo.
