No, StatCounter does not have that category, but I did download data for every country in the list of 54 countries which are members. The results are mixed. The mean share by country is 1.16%. However, if you weight shares by population, the mean share is 1.54%, mostly thanks to India with 1.95% share and a huge population…
The total population amounts to 2.317billion people. The population-weighted share comes to 35.6million people. To be fair, countries like India have very low rates of connection to the Internet but that is changing rapidly and many millions are using GNU/Linux and Android/Linux today. The Commonwealth, being connected with English may be sampled with less bias than countries with other languages and suggests that a good part of the world has left ~1% behind. In March 2010, India was at 1.15%.
Kenya was very high then and has declined but is still doing well. Also, Android/Linux has taken a lot of traffic in Kenya.
According to StatCounter, their data should not be used this way but the approach is reasonable. It suggests that globally, we are near ~100million people using GNU/Linux assuming other countries follow these trends. If the number of users doubles in the next five years the world will be a very different place. The high rates of growth in India and Europe suggest this is very likely sooner rather than later. It’s all good. Freedom is coming to the ordinary person using IT.
