I have been following the popcon stats in order to figure out the real
number of Greek installations of Ubuntu.
There should be a multiplier that you apply to the value that popcon
gives you, and you get the total installations for your language.
If you can get a random group of Ubuntu users in your country, you can
check their computers and verify
how many of them have actually enabled to send these popcon stats.
Then you can adjust the value that popcon gives you.

Even if your random group is not random enough (for example, there are
advanced users who tinker every option),
then you can use this ratio to establish the lower bound of Ubuntu
users for a specific language. For example,
if half of your random group uses popcon and installed the langpack,
then AT LEAST the double of your popcon number corresponds
to the minimum of Ubuntu users for the said langpack.
