Jeremy Zawodny makes the observation that I’ve made a couple of times; namely, Google’s PageRank is broken. (OK, he’s said it more than once.)
In the comments, Phil Ringalda defends Google on the grounds that Jeremy’s page is as good a result for the search terms in question as anything. He discusses the issue further on his own blog.
I would just like to note that I am currently the top result for google://population+of+indianapolis.
