What's up with the 48 year olds?

[AdamTReineke]

There are 148 of them, I'd wager there are a couple with super-high stats who throw off the average.

Also note the significant 34 y.o. bump from the legendary Jon Skeet [1]

Using a median instead of a mean might help w/ this.

Yes - median is a far better method to use in a situation like this, especially when what is being measured (reputation) has a bounded minimum and an unbounded maximum, and double especially when the sample size in each age bucket is relatively small.

If you look at original linked doc, you'll see that there are three 68-yr olds, that have on average 19.000+ points. That's why I only used in graphs age groups that have at least 100 developers.
