Re: Developers per country (2013)
Hi folks,
This is a reply to Christian's article [1], which is interesting as always.
[1] http://www.perrier.eu.org/weblog/2013/07/27#devel-countries-201307
First, let's see how the number of active developers and population are
really related. The correlation coefficients are:
0.10 (2013), 0.09 (2012), 0.09 (2011), 0.08 (2010).
Very low, unfortunately. But it was predictable...
Next, let's analyse how the number of developers in country is depended on
standard of living. GDP [2] per capita (based on International Monetary Fund
figures [3] for 2012) is chosen as an indicator of the standard of living.
This ratio can be interpreted as a conditional measure the effectiveness of
the country in the field of Debian development. (In other words, how much
money is needed for production or for attracting a single Debian developer in
given country).
Or it can be interpreted as a response to the question "where Debian
developers live well". (If we assume, that Debian developers may move freely,
they should be concentrated in places with the best conditions for their
life).
This is not my idea to use GDP for statistic analysis [4], but I found it
quite attractive. So all data were re-calculated and this note was prepared.
[2] https://en.wikipedia.org/wiki/Gross_domestic_product
[3] https://en.wikipedia.org/wiki/List_of_countries_by_GDP_%28PPP%29
Data for Luxemburg were taken here: https://en.wikipedia.org/wiki/Luxembourg
Data for Cuba were taken from CIA World Factbook (1993–2012).
[4] http://www.opennet.ru/opennews/art.shtml?num=34040 (in Russian)
And here is the list, sorted by the ratio of *active* developers per GDP for
each country.
GDP: GDP data in trillions (10^12) of international dollars
GDP/P: GDP per capita in thousands of international dollars
Act: number of active developers
Dev: total number of developers
A/G: number of active developers per GDP
D/G: number of all developers per GDP
2013: rank in the list, sorted by the ratio of active developers per GDP;
data for 2013 (July)
2012: rank in the list, sorted by the ratio of active developers per GDP;
data for 2012 (June)
2013P: rank in the list, sorted by the ratio of active developers per
million population; data for 2013 (July)
2012P: rank in the list, sorted by the ratio of active developers per
million population; data for 2012 (June)

A few interesting facts:
* Finland is on top of the list again. Really impressive!
* There are no reliable GDP data for Martinique, it is a part of France from
financial point of view. This DD might be added to France, but I preferred
to drop this string. I am sorry, David, you were not counted.
* China and Mexico are in the end of list. In order to "create" one DD these
countries should "work" arduously in 120 and 160 times more than Finland.
The correlation coefficients between the number of active developers and GDP:
0.60 (2013), 0.60 (2012). Hey, it looks much better!
Make conclusions on your own. =)
Best wishes,
Boris

This is not a refutation of Christian's article, but an addition to it.
PPS:
I do not have web blog, because I am not interested in such kind of activity.
