If it's shared in a corporate environment or anonymously, it shouldn't. I generally expect most of the people I work with the be in a +/- 10% band for my "peers", and +10-50% for my immediate management level, which my understanding is pretty accurate from the numbers I've seen.

On the US West Coast, variance is far more than that, unless you circularly define "peers" as people who negotiated the same level/pay as you.
