- Why doesn't this figure match the country's official statistics?
- The UN estimates the population of every country with the same method, based on censuses, surveys and registers, and projects it year by year. Each national statistics office uses its own censuses and registers, which may be more up to date or count foreign residents differently. That is why the figures can differ slightly.

Where these figures come from
The figures are estimates from the United Nations Population Division, published in World Population Prospects 2024 (medium variant): the reference used by international organizations and by most population counters. The UN estimates how many people there are on July 1 of each year and how many are born, die and migrate; between one date and the next, this counter spreads the change continuously, second by second.
It is not a real-time headcount: nobody can count every person in a country at once. It is the best available estimate, and it may differ slightly from the figures of each country's statistics office, which use their own censuses and population registers.
