2023 - Ten Million Registered Users

In January 2023, OSM reached 10 million users over the life of the project.

As user janjko pointed out on r/OpenStreetMap, most of the edits are produced by about .1% of the users. However, as user joostjakob pointed out in the same thread, “while you need the power users to do most of the work, those millions of other eyes can fill in the gaps. While power users might touch a million nodes when remapping land use, a thousand people adding one or two extra POIs have as much added value.”
