Note that they use "average" instead of median.

I'm sure more super-rich people read it than super-poor people, so this average is a bit aliased.

Good point. If Bill Gates subscribes, he alone adds about $33k to the average net worth of their 1.7 million print subscribers.

I very much doubt a census was taken. The page says the source is from a "2007 WSJ Subscriber Study." It is very doubtful Bill Gates was part of this study. In all likelihood, they polled a relatively small random sample and the median was pretty close to the average.
