http://people.debian.org/~spaillard/developers-age-histogramm/ actually also contains historical data. Fortunately, it also shows the average age increases slower than time: over 2012 (12 months so), average age increased by 2.7 months only. Consider the figures below with caution, as it's computed from rounded to year data, hence the big jump at year transition. 2010-04-11 mean = 33.1036 2011-03-19 mean = 34.0884 2011-05-13 mean = 34.0711 2011-06-01 mean = 34.107 2011-07-01 mean = 34.107 2011-08-01 mean = 34.0982 2011-09-01 mean = 34.0963 2011-10-01 mean = 34.0879 2011-11-01 mean = 34.1322 2011-12-01 mean = 34.112 2012-01-01 mean = 35.1168 2012-02-01 mean = 35.0846 2012-03-01 mean = 35.1131 2012-04-01 mean = 35.0561 2012-05-01 mean = 35.0864 2012-06-01 mean = 35.0668 2012-07-01 mean = 35.0569 2012-08-01 mean = 35.052 2012-09-01 mean = 34.9782 2012-10-01 mean = 34.969 2012-11-01 mean = 34.9706 2012-12-01 mean = 34.8928 2013-01-01 mean = 35.8746 2013-02-01 mean = 35.8918 -- Simon Paillard -- To UNSUBSCRIBE, email to debian-project-requ...@lists.debian.org with a subject of "unsubscribe".
