The following breakdowns of non-mobile and mobile traffic are based on our squid logs.
Note how share of mobile usage peaks every year around Christmas.
Note how mobile here is to be taken as ‘traffic from mobile devices’ not as ‘traffic to our mobile site’.
See also the Wikipedia article on usage share by browser.
Since early 2008 we publish traffic stats per Wikimedia wiki in detailed reports.
In the past 4 years the relative proportion of page requests per project did not change much. All projects received more traffic, more or less in proportion to their earlier size. Wikipedia share rose from 95.7% in July 2008 to 96.4% in January 2012. Most of this relative gain was at the expense of Wiktionary which fell from 1.5% in July 2008 to 1.0% in January 2012.
Here are updated diagrams about the breakdown of page requests per project, first in absolute numbers, second in share of overall total:

Two years ago Wikimedia board member Stu West published the first version of the map above. I was asked to produce an updated version for presentations.
Countries are colored by monthly Wikipedia page views per internet user (2011 Q4). Overlayed on the map are monthly unique visitors per region (Dec 2011).
Data used:
Country coloring: Wikipedia lists internet users per country & population per country
+ page views per country -> aggregate data
Unique visitors per region: data kindly supplied by internet research company comScore
1) comScore publishes one UV count for Middle East & Africa combined (40 M in map above).
2) In many countries the number of internet users grows rapidly from year to year. Not all data in the Wikipedia lists are quite up to date. This can influence the shown ratio significantly. I hope some day we will have a more up to date data feed from e.g. World Bank, which publishes tons of metric via a very flexible API.
3) Like Stu I used this neat mapping tool http://gunn.co.nz/map/
4) With current coloring it is a bit difficult to see the which countries have 15 views per internet user, which have 25. No large countries rise above 17 views per user. Check for details page views per country.
Here are a few plots and data I collected for the SOPA blackout from 18 January. Wikimedia Foundation is working on a wider coverage of the event.
Note that on the second day hourly hits to Special:CongressLookup page exceeded hits to SOPA_initiative/Learn_More. Probably part of the demand came from external referrers.
The huge dip in CongressLookup hits on the first day was during hours where most US citizens were asleep. Of course the CongressLookup page did not make much sense for non-US citizens.
Here is a list of most visited SOPA related pages on different Wikipedias during the blackout (24 hrs only).
Overall page requests to English Wikipedia during the blackout was not particularly high or low.
In May 2011 I presented a new visualization tool which can playback all 400,000 Wikipedia edits for a random day, and show where and when these edits occurred, and for which language wiki. The tool also shows static maps for at-a-glance view of the global distribution of edits for a full day.
Recently I added two new maps:
This map (in the tool press 4) shows the global distribution of page views for all Wikipedia’s combined. Clearly certain parts of the world are better reached than others. No surprises here, but with this map you can examine this disparity in considerable detail.

The data shown are normalized for area, which allows direct comparison with a population density map (by SEDAC). In split screen mode you can see both page views and population density side by side: press ‘d’ (for density) repeatedly.
This map (press 5) shows the percentage of requests originating from mobile devices.
Percentage of page views from mobile devices
Note how these requests do not have to be directed to our mobile site. In fact roughly half of these requests go to the main site. As the coloring shows this percentage is quite different for different language projects. The English Wikipedia receives a far larger share of traffic via mobile devices than most other language projects. If you zoom in on Europe you can see clearly how UK stands out against e.g. Germany and France, where economic conditions are roughly comparable.

Detection of mobile device is done by scanning for certain keywords in the agent string as contained in the meta data which our servers receive for every request. Page views are per square kilometer. For each page view log record from our 1:1000 sampled log the ip-address is translated into latitude and longitude, using the free Maxmind database. Views are accumulated for a whole month per small region (here 1/8 degree squared), averaged per day, corrected for projection distortion (any projection of a 3D globe to a 2D surface produces substantive distortions) and colored for intensity. Cycle with ‘d’ between page views [V], split screen [V|D], split screen opposite [D|V], population density [D]. Known issue: both page views and population density screens do not pan in sync, therefore no split screen at larger zoom levels. But you can still alternate between both full screen views. Compare global share of views from a mobile device as shown here (~12%) with share of mobile views to our mobile site (~6%) shown in our monthly report (column Wikipedia Mobile, top-right percentage).
