Somewhere around 100 million physical servers are in operation, concentrated overwhelmingly in a small number of very large facilities: there are roughly 1,000 hyperscale data centres worldwide and perhaps 8,000 to 11,000 data centres of any size. About 12 million servers ship each year. Data centres consume roughly 1 to 1.5% of world electricity, a share that had been flat for a decade thanks to efficiency gains and is now rising again because of AI workloads. ## How the figure is arrived at Server shipments are tracked per quarter by vendor; the installed base follows from a replacement cycle of about five years. Cloud providers do not disclose fleet sizes, so their capacity is inferred from data centre floor area, disclosed power draw and known rack densities — an indirect chain that makes the total uncertain by tens of percent. ## How confident it is - **Low estimate:** 70,000,000 - **High estimate:** 130,000,000 - **Spread:** 1.9× between the bounds ## Other things people built counts - [How many countries are there in the world?](https://atoneplace.net/how-many/countries/) — 195 — or 193, or 206, or 249, depending on who is counting - [How many cars are there in the world?](https://atoneplace.net/how-many/cars-in-the-world/) — about 1.5 billion motor vehicles - [How many planes are in the air right now?](https://atoneplace.net/how-many/planes-in-the-air-right-now/) — roughly 10,000 to 20,000 at any moment - [How many languages are there in the world?](https://atoneplace.net/how-many/languages/) — about 7,150 living languages - [How many McDonald's are there?](https://atoneplace.net/how-many/mcdonalds-restaurants/) — about 43,000 in over 100 countries - [How many phones are there in the world?](https://atoneplace.net/how-many/phones-in-the-world/) — about 8.9 billion mobile connections — more than there are people - [How many nuclear weapons are there?](https://atoneplace.net/how-many/nuclear-weapons/) — about 12,200 warheads - [How many websites are there?](https://atoneplace.net/how-many/websites/) — about 1.1 billion hostnames — but only around 200 million active - [How many books have ever been published?](https://atoneplace.net/how-many/books-ever-published/) — about 130 million as of 2010 — probably over 200 million now - [How many airports are there in the world?](https://atoneplace.net/how-many/airports-in-the-world/) — about 45,000 with runways — but only around 4,000 with scheduled airline service - [How many ATMs are there in the world?](https://atoneplace.net/how-many/atms-in-the-world/) — about 3 million - [How many cities are there in the world?](https://atoneplace.net/how-many/cities/) — about 10,000 with over 50,000 people; 33 megacities over 10 million - [How many buildings are there in the world?](https://atoneplace.net/how-many/buildings-in-the-world/) — somewhere between 1.5 and 4 billion - [How many computers are there in the world?](https://atoneplace.net/how-many/computers-in-the-world/) — roughly 2 billion personal computers in use ## Common questions ### How many servers are there in the world? roughly 100 million ### How is that estimated?
