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) Code Country GDP Population GDP/P Act Dev A/G D/G 2013 2012 2013P 2012P fi Finland 0.198 5259250 37.6 19 31 96.0 156.6 1 1 1 1 nz New Zealand 0.129 4331600 29.8 10 15 77.5 116.3 2 3 7 7 ie Ireland 0.191 4670976 40.9 12 15 62.8 78.5 3 4 2 2 se Sweden 0.396 9088728 43.6 22 37 55.6 93.4 4 5 5 5 ch Switzerland 0.362 7870134 46.0 20 27 55.2 74.6 5 6 3 3 de Germany 3.194 81471834 39.2 165 235 51.7 73.6 6 7 8 9 mg Madagascar 0.021 21281844 1.0 1 1 47.6 47.6 7 2 50 40 at Austria 0.359 8217280 43.7 16 26 44.6 72.4 8 10 10 10 fr France 2.253 65350000 34.5 100 130 44.4 57.7 9 9 11 11 no Norway 0.278 4973029 55.9 12 15 43.2 54.0 10 8 6 6 be Belgium 0.421 11071483 38.0 14 17 33.3 40.4 11 13 13 13 au Australia 0.961 22607571 42.5 31 59 32.3 61.4 12 16 12 12 uk United Kingdom 2.316 62698362 36.9 73 114 31.5 49.2 13 14 14 14 lt Lithuania 0.064 3535547 18.1 2 2 31.3 31.3 14 12 21 22 bg Bulgaria 0.104 7364570 14.1 3 3 28.8 28.8 15 11 27 23 lv Latvia 0.037 2204708 16.8 1 1 27.0 27.0 16 17 26 27 nl Netherlands 0.710 16728091 42.4 19 40 26.8 56.3 17 18 15 15 hu Hungary 0.197 10076062 19.6 5 10 25.4 50.8 18 15 24 20 hr Croatia 0.080 4290612 18.6 2 2 25.0 25.0 19 19 25 26 es Spain 1.407 46754784 30.1 35 56 24.9 39.8 20 22 18 18 dk Denmark 0.210 5529888 38.0 5 10 23.8 47.6 21 20 17 17 lu Luxemburg 0.042 503302 83.4 1 1 23.8 23.8 22 21 9 8 ca Canada 1.446 33476688 43.2 32 61 22.1 42.2 23 23 16 16 cz Czech Republic 0.287 10190213 28.2 6 6 20.9 20.9 24 24 20 21 it Italy 1.834 59464644 30.8 36 51 19.6 27.8 25 25 19 19 uy Uruguay 0.054 3477778 15.5 1 2 18.5 37.0 26 26 28 28 cr Costa Rica 0.059 4301712 13.7 1 1 16.9 16.9 27 27 31 31 il Israel 0.248 7740900 32.0 4 6 16.1 24.2 28 28 23 25 by Belarus 0.150 9577552 15.7 2 2 13.3 13.3 29 39 32 39 gt Guatemala 0.078 13824463 5.6 1 1 12.8 12.8 30 – 43 – rs Serbia 0.080 7186862 11.1 1 1 12.5 12.5 31 – 38 – pl Poland 0.802 38441588 20.9 10 14 12.5 17.5 32 29 30 30 us USA 15.653 313232044 50.0 173 378 11.1 24.1 33 31 22 24 br Brazil 2.366 192376496 12.3 21 23 8.9 9.7 34 32 40 38 cu Cuba 0.121 11241161 10.8 1 1 8.3 8.3 35 33 41 41 pt Portugal 0.245 10561614 23.2 2 4 8.2 16.3 36 34 34 34 ar Argentina 0.747 40677348 18.4 6 8 8.0 10.7 37 30 37 32 jp Japan 4.617 127078679 36.3 35 50 7.6 10.8 38 35 29 29 sk Slovak Republic 0.132 5477038 24.1 1 1 7.6 7.6 39 36 36 36 ec Ecuador 0.135 15007343 9.0 1 1 7.4 7.4 40 37 45 43 gr Greece 0.281 10787690 26.0 2 3 7.1 10.7 41 38 35 35 co Colombia 0.500 45566856 11.0 3 4 6.0 8.0 42 40 46 47 za South Africa 0.579 50590000 11.4 3 10 5.2 17.3 43 42 48 48 ve Venezuela 0.402 28047938 14.3 2 2 5.0 5.0 44 48 44 49 ro Romania 0.274 21904551 12.5 1 2 3.6 7.3 45 41 51 46 tw Taiwan 0.902 23040040 39.1 3 3 3.3 3.3 46 43 39 37 cl Chile 0.319 16746491 19.0 1 2 3.1 6.3 47 44 47 44 pe Peru 0.325 29907003 10.9 1 1 3.1 3.1 48 45 53 51 sg Singapore 0.327 5183700 63.1 1 1 3.1 3.1 49 46 33 33 ua Ukraine 0.345 45134707 7.6 1 1 2.9 2.9 50 58 55 59 ru Russia 2.512 143030106 17.6 7 8 2.8 3.2 51 47 49 45 kr South Korea 1.622 48754657 33.3 4 6 2.5 3.7 52 49 42 42 my Malaysia 0.492 28250000 17.4 1 1 2.0 2.0 53 50 52 50 in India 4.711 1210193422 3.9 9 9 1.9 1.9 54 53 60 57 eg Egypt 0.538 80081093 6.7 1 3 1.9 5.6 55 51 57 55 tr Turkey 1.125 74724269 15.1 2 2 1.8 1.8 56 52 54 52 th Thailand 0.646 66720153 9.7 1 2 1.5 3.1 57 54 56 54 cn China 12.383 1344413526 9.2 10 14 0.8 1.1 58 56 59 56 mx Mexico 1.758 112336538 15.6 1 1 0.6 0.6 59 55 58 53 sv El Salvador 0.046 7066403 6.5 0 1 0.0 21.7 60 57 61 58 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 PS: This is not a refutation of Christian's article, but an addition to it.
