operating system share
operating system share is the percentage of a measured population - web pageviews, crawled sites or surveyed gamers - running each OS version. In Datadory's catalog of 1,744 datasets, StatCounter OS Market Share and W3Techs OS Usage for Websites are working examples.
What is operating system share?
Operating system share is the percentage of a measured population - web pageviews, crawled sites or surveyed gamers - running each OS version.
This slice measures it three ways: StatCounter from pageviews, W3Techs from server-side crawling, and Valve's Steam survey from opt-in hardware telemetry.
In this catalog it appears concretely: - StatCounter OS Market Share — "monthly/daily OS share worldwide and by country since January 2009, CSV download, commercial delivery terms-SA 3.0". - W3Techs OS Usage for Websites — "Unix-family vs Windows server shares, free history from 1 August 2025". - Steam Hardware & Software Survey — "monthly Windows 11/10, macOS and Linux shares from voluntary user telemetry".
W3Techs OS Usage for Websites is the second reference point worth knowing: "Unix-family vs Windows server shares, free history from 1 August 2025". Reading the two together shows how much variation sits underneath one shared label.
Why does operating system share matter when choosing a dataset?
Conventions decide whether two sources can be joined at all. Buy one side of an analysis that ignores this convention and every reconciliation step — calendar alignment, unit conversion, entity matching — lands on your team instead of the vendor's.
The failure mode is concrete: a source can carry the operating system share label while differing from what you need on exactly the dimension that matters — monthly/daily OS share worldwide and by country since January 2009, CSV download, commercial delivery terms-SA 3.0. Comparing two sources on that line usually settles the choice faster than any feature matrix.
You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and StatCounter OS Market Share lets you inspect the real artifact before any budget is committed.
How do you evaluate operating system share in a data source?
Treat every claim of this attribute as testable:
- Open StatCounter OS Market Share and confirm its record — "monthly/daily OS share worldwide and by country since January 2009, CSV download, commercial delivery terms-SA 3.0" — against the files you actually receive. 2. Open W3Techs OS Usage for Websites and confirm its record — "Unix-family vs Windows server shares, free history from 1 August 2025" — against the files you actually receive. 3.

Frequently asked questions
What is an example of operating system share?
StatCounter OS Market Share is the clearest example in this catalog. Its record states: "monthly/daily OS share worldwide and by country since January 2009, CSV download, commercial delivery terms-SA 3.0". Across all 1,744 datasets Datadory averages a quality score of 7.81 out of 10, so a named example can be weighed rather than trusted blindly.
Is data described as "operating system share" free to use?
Treat access and permission separately. 82.4% of the 1,744 datasets in this catalog are free to access, but 235 are freemium and 61 are paid outright, so confirm both the price and the license on the exact distribution before building on it.
How do I verify a source really provides operating system share?
Open StatCounter OS Market Share next to W3Techs OS Usage for Websites and compare the promise with the download. Field definitions are verified for 1495 of 1,744 datasets (85.7%), which makes that check fast inside the catalog and manual outside it.
