OSMF regular member distribution

Posted by dieterdreist on 4 May 2017 in English (English)

Probably everybody has guessed it, but here is a proof with Jan 2017 data: OSMF members are mostly living in Europe and the US, with a concentration in London, Germany, and in the US on the East Coast (Washington and NYC) and in the Silicon Valley.

Thanks for the effort but providing the underlying data would probably be more useful.

Side note: it never ceases to amaze me how people think that blurring data somehow improves the value of an illustration. A simple dot density or proportional symbol map would be much less distorting. And of course an equal area map projection is generally considered a hard requirement for this kind of illustration as well.

Thank you for the comment. I got the data from OSMF with the premise not to redistribute it and not to be too detailed when displaying it on a map so that single members cannot be inferred.

The original map I posted was in EPSG 54016 which is kind of a compromise and indeed not equal area. Following your suggestion I have now replaced it with Eckert IV (EPSG 53012) which is an equal area representation.

This is the first version version for reference:

I don't think that was really more successful with you blurred style than it would have been with a more objective display method. All the feint isolated dots are clearly individual members. In your map you don't really get a good idea how many more members there are in Europe than in the US. It could easily be anywhere between three times and 30 times as many.

Maybe you could give us member numbers per country for the US, Canada and Europe.

I just saw that I can pass the data to other OSMF members.

Wow, that means membership increased by nearly 100 members in half a year.

On 2014-11-30 there were 245 regular members, so this seems quite possible. The data above is from Jan 6, 2017

According to http://wiki.osmfoundation.org/wiki/Membership/Statistics there were 396 normal members in November 2016 so if there were 485 in early January that is almost frightening.

You are correct, on closer inspection I counted expired memberships as well.

Sometimes I feel like expiring ;-)

I get 396 normal members if I remove everyone whose membership expired before 2016-05-22 (some members pay later, but after a while you would assume they are not interested any more, something seems slightly strange anyway).

On 7, Jan 2017 (and members paid up until three months earlier) I get these numbers: total: 349

63 United States

63 United Kingdom

56 Germany

15 Switzerland

14 France

13 Canada

12 Russian Federation

12 Netherlands

10 Italy

8 Spain

8 Belgium

6 Australia

Good evening, It is with great bitterness that I see that there are not many Africans at the level of the members of the OSM foundation. Indeed, I wonder what is the explanation for such a fact? How do you become a member of the foundation or be a local chapter? Is information about the importance of being a member of the foundation known to all?

I am a member since 2016 and I have to say that I find that "role" model with three different types confusing and might frighten some potential users to join.
