Not exactly the statistics you were looking for, but here are some
statistics that might be relevant never the less. They were generated
from the changeset dump:
There are as of now 461697 accounts signed up. Of those 199005 have made
at least one edit (or better to say show up in the changeset dump). That
is about 43% of signed-up users make an edit.
of those mappers
118876 users edited less than 3 changesets
34442 users edited less than 10 changesets
21726 users edited less than 31 changesets
11785 users edited less than 100 changesets
6899 users edited less than 316 changesets
3538 users edited less than 1000 changesets
1373 users edited less than 3162 changesets
322 users edited less than 10000 changesets
44 user edited more than 10000 changesets
Mappers who have edited something in the last week have had the
following "age" distribution, where age is the time since their first
edit, not when they signed up (that information is not readily available)
1208 users edited with an age of less than 5 days
244 users edited with an age of less than 20 days
255 users edited with an age of less than 45 days
226 users edited with an age of less than 80 days
243 users edited with an age of less than 125 days
274 users edited with an age of less than 180 days
247 users edited with an age of less than 245 days
292 users edited with an age of less than 320 days
298 users edited with an age of less than 405 days
330 users edited with an age of less than 500 days
358 users edited with an age of less than 605 days
459 users edited with an age of less than 720 days
434 users edited with an age of less than 845 days
380 users edited with an age of less than 980 days
409 users edited with an age of less than 1125 days
238 users edited with an age of less than 1280 days
124 users edited with an age of less than 1445 days
45 users edited with an age of less than 1620 days
18 users edited with an age of less than 1805 days
11 users edited with an age of less than 2000 days
7 users edited with an age of less than 2205 days
A graph of the number of mappers per week who have done their first
edits in a given week can be found at
http://wiki.openstreetmap.org/w/images/6/6f/Contributor_signup.png
Currently roughly 1200 new mappers do their first edit per week and this
number has stayed more or less constant (with large fluctuations) since
about mid 2009.
Together, these metrics can potentially give some indication of whether
any site re-design has a significant effect on recruiting mappers,
although there are obviously many other factors playing into how many
people become mappers and many factors of a site design that are not
captured.
