CZ:Statistics

Here we present basic statistics concerning the project.

For some technical reasons, the graphs are scaled in working days. Here is the translation into the calendar dates.

1  : 2006-10-22
50 : 2006-12-11
100: 2007-01-30
150: 2007-03-21
200: 2007-05-10
launch: 2007-03-28, i.e. 157th working day
last pictured day = 2007-05-17

Pages

Number of articles and pages The first graph shows the number of articles (technically speaking, all pages from mainspace without redirects). Observe an acceleration after the launch (about 150). As a trivia fact, one may notice a small jump about 50th day. What was it? On December 7, 2006, some viper articles were uploaded. Fig. 1. Number of articles

The second graph shows number of all pages from all namespaces (e.g. userpages, talk pages and images are included, redirects are _not_). This is the green line. The blue line is the one from the first graph (i.e. the mainspace pages). What happened about 125th day? It was Saint Valentine's, 14/02/2007, when after slashdotting many new users registered (and were welcomed on their talk pages!). Notice that at the same time there was no parallel growth in the mainspace. Apparently, the newly registered users were mainly watching, since at that time there was no unregistered access. Again, a more stable growth rate has been established after the launch. Fig. 2. Number of all pages from all namespaces without redirects (green) and articles (blue)

Rate of article and page creation

The third and forth figure present "global creation rate". It measures somehow the activity on the wiki expressed in new pages per day. The rate for "pure" articles (technically: mainspace without redirects) is depicted in blue; the green line corresponds to all pages (still, without redirects). This is calculated as the number of articles (pages, respectively) divided by the number of working days from the beginning. Obviously, this is a "global average" and the recent creation rate is higher than the one on the beginning. This can be seen on the 5th and last graph of this section, which represents the creation rate for articles taking into account last 30 days only.

Human resources

Number of authors

The following graphs describe the CZ human resources.

• How many authors edit each month? See Fig. 6 below.

Fig. 6. Editing authors

• How many users are active? If by "activity" we define at least 20 edits per month, and by "high activity" we understand at least 100 edits per month, then the answer is given by the Fig. 7 below.

Daily use

How many users you could meet here daily? While correlated with other HR measures, this one seems to be interesting since it shows how many people make the community on a daily basis. See the figure below.

Fig. 8. Authors daily

New arrivals

• Fig. 9: How many new authors arrive each month? This can be measured by counting new user pages. More substantial measure would be, however, to detect a new user on his first edit. Notice that in the period of self-registration (essentially, February 2007) the two measures largely coincide, as the new users were supposed to provide their bio.

Comparison to other wikis

• What is the real meaning of these figures? Is the Citizendium wiki strong enough in terms of human resources? What can it be compared with? April 2007 is the first month after the launch, so let us refrain from making parallels to the English Wikipedia. Still, finding some quite big, active and successful projects to compare with could be of some interest. Maybe an other language Wikipedia? Suppose that we count the registered users only, considering that IP anonymous users, while numerous, globally make not too many edits (8-15%, depending on the wiki) and rarely an IP is really active (makes more than 20 edits). Excluding those active IPs is somewhat compensated by the fact that, for the sake of simplicity, we count Wikipedia 'robots' as regular users.

Fig. 10. CZ - WP human resources comparison

Then it turns out that, as of April 2007, the human resources of CZ in terms of the above figures are comparable to resources of some Wikipedias from the category "more than 25,000 entries" (as listed on the Main Page of the English Wikipedia). For example, CZ would be of the same order of magnitude as hr.wikipedia.org, lt.wikipedia.org, sl.wikipeida.org (these were slightly smaller) or sr.wikipedia.org (this one was a bit bigger than CZ). As a sidenote, there were not many active IP anons on these wikis (about 10), roughly as many as robots that were taken into account. Notice also that there are 24 Wikipedias altogether in the categories "more than 50000", "more than 100000" and "more than 250000" entries.
