Most of the sample (60%) worked between 40 and 45 hours per week, with 3% working over 55 hours. European work patterns tended to match world patterns in terms of hours put in. Work week correlated well with salary and produced a coefficient of +$988 per hour—much higher in Europe than in the global model. (As mentioned earlier, those who reported a work week shorter than 30 hours were not included in the model.)
As with past languages, the coefficients for future languages do not lend themselves to obvious explanation: Erlang (–$3,867), Ruby (–$5,363), and C# (–$7,721) all had negative coefficients.
