Counted from the public server list, not guessed
Yes. In a typical hour over the last 30 days we counted about 1,620 human players spread across roughly 680 active public Counter-Strike 1.6 servers, with busy hours reaching just over 4,000. That is a small game by modern standards and a remarkably large one for a title released in 2000, and the shape of it is more interesting than the headline.

Server counts move less than player counts. A typical hour shows 679 servers responding, with a high of 1,236. The population thins out overnight far more than the server list does, because most of those servers stay up whether anyone is on them or not.
The figure people usually quote for a game like this is the raw player count, and for Counter-Strike 1.6 that number is inflated. In the same 30 days, the average hour held 2,224 bots against 1,620 humans.
So a server browser showing 12/16 players is often showing you nine bots and three people. This is not deception on anyone's part: filling empty slots with bots is a normal way to keep a server looking alive enough that someone joins it. It does mean that judging the game's health from the numbers in the browser will mislead you upward.
Activity concentrates hard. The classic bomb-defusal maps carry most of it, with de_dust2 far ahead of everything else, and the surviving community modes - zombie, gun game, jailbreak, deathmatch - hold most of the rest.
The niche movement modes are much smaller than their reputation. Across four months of scanning we saw surf running on 69 distinct-server sightings in total and bhop on 166, against hundreds of servers for a single popular bomb map. Those scenes are alive, but they are small enough that you will often be practising alone.
This counts servers that report to the public master list. Private servers, password-protected servers and LAN games are invisible to it, and in some regions a substantial amount of play happens on servers that never advertise publicly.
It is also a 30-day window measured from one vantage point. Treat it as a good estimate of the public scene rather than a census of everyone playing.
If you want a populated server on a well-known map at a reasonable hour, you will find one. If you want a specific niche mode on a specific map at four in the morning, you may be the only person there.
The game is old enough that the people still playing are mostly there deliberately, which makes the average server calmer and more competent than the raw numbers suggest.
