Armed forces personnel
Active-duty military personnel, including paramilitary forces where their training and command resemble the military.
How it is measured
IISS-derived counts republished by the World Bank.
Where the number came from
The International Institute for Strategic Studies has published The Military Balance annually since 1959, and it remains the standard open reference for who has how many of what. Counting soldiers sounds simpler than counting money and is not: the count depends on whether conscripts serving twelve months are equivalent to career professionals, whether reserves are included, and how to treat the large armed formations that sit outside the defence ministry, such as gendarmeries, border troops and internal security forces, which in some states outnumber the regular army. Force-size comparison also carries a long record of being wrong in ways that mattered, from the pre-1914 mobilisation tables to Cold War bean-counting that measured divisions rather than readiness. The number is a genuine input to analysis and a poor summary of one.
Worked example: a table frozen in 2020, and why we still publish it
Every substantive row in this table carries the observation year 2020, because the World Bank series has not been updated globally since. It shows India at about 3,068,000, China near 2,535,000, North Korea about 1,469,000, Russia roughly 1,454,000 and the United States around 1,395,000. Look at what that vintage excludes. It predates Russia’s February 2022 invasion of Ukraine, the partial mobilisation announced later that year, and every subsequent change to both the Russian and Ukrainian armed forces; it predates the expansion of European forces that followed; it predates several announced Chinese and Indian restructurings. For the two countries where this indicator has been most discussed since, it is simply not current. We publish it anyway, with the year attached, for the reason we publish everything with a year: a stale figure that announces its age is usable, because you can decide whether five-year-old force levels answer your question, while the same figure stripped of its date is a trap. If your question is about the current balance in Europe, this is the wrong table and you should go to a current IISS or national source. If your question is about the long-run scale of the world’s largest militaries, five years changes very little and this table is fine.
Figures read from our own armed forces personnel table; each row there carries its observation year and whether it came from a live feed or the frozen archive.

What to watch for
This series is stale by half a decade and we label it accordingly. Reserves, conscription systems, and paramilitary definitions vary; headcounts say nothing about capability.
