Hello, I'd just like to know if you have any good statistics concerning this question :

What is the average time a developer stays in the same company ?

I'm asking this question because I often get the feeling that developers don't stay too long in the same company, but I'd like to know if there are any statistics I could look to find out whether this feeling is true or not (and to what extent it is far or near from the truth).

I'm more interested in statistics where the developer chose to left (i.e had the choice to stay but decided to leave, wasn't fired or the company went bankrupt or something of the same kind).

I thought this would be the best place to get some answers, and I'd like to know if you would by chance have any resource I could look upon.

Also, on a related note, am I the only one with this feeling or is it something other people here think as well ?

Thank you for your time.
