I live in Norway and a member of a union for engineering (broad branches thought) and this is also a kind of statistical analysis they do every year on their 81500 members. They take in consideration the experience years and different fields, as well as public vs private sector. They have improved quite a bit in the last few years on the metrics they present but I don't think geographic metrics have been shown as there are only a couple of big cities where population is concentrated.
