The out of date data is due to the (poor) interaction of the external data feed and the semantic wiki. Long story short: They don't play together well. I had been manually starting a semantic update every few days for quite a while, but stopped early last year when life got crazy... I started one now. Maybe I can remember to do one every now and then. This is why the various realm pages are showing out of date information.
The Economy portion of the Region pages is, at the moment, irrelevant. It is a partially implemented system that never made it into actual use. It is there now just for flavor text, I suppose.
