[Osmf-talk] How many people could get free OSMF Active Contributor membership? (see inside!)

[Amanda McCann]

I wanted to know how many people could get free OSMF membership, so I made a tool to calculate it.

If you have edited OSM for ≥42 days of the last year, you're entitled to free membership (or assoc. membership) of the OpenStreetMap Foundation under the [Active Contributor Programme](https://supporting.openstreetmap.org/active-contributor-membership/)¹. Tools like [Pascal Neis' How Did You Contribute (hdyc)](https://hdyc.neis-one.org/) show if you're entitled.

But then [I asked myself](https://en.osm.town/@amapanda/112401462200188820): How many people *could* get it? There are [currently 2,300 OSMF members](https://osmfoundation.org/wiki/Membership/Statistics). How many OSMF members _could_ we have!

So I made a little programme that scans an OSM history file, and calculates how many editing days every user has, and save that to a big CSV file. 🙂 It shows if someone is over the 42 days or not, as well how many editing days in total

You could use this on the full planet file to get the list of **10,000 OSMers** who are entitled to OSMF free membership.

You can also use this on a region specific history file from Geofabrik to get a smaller list of users for just your users, but that'll only have a subset.

Full history files can be downloaded from the [OSM planet service](https://osm-internal.download.geofabrik.de/) or per region from the [Geofabrik OSM Download Service (for OSM users)](https://osm-internal.download.geofabrik.de/).
