Yah, just go up to the top here to "Community" and click "Game Stats". It gives the top ranked towns in Population Numbers and Wealth.
Be carefull not to mistake these statistic for a "Top Ten list" of any sort. Numbers and wealth are deceiving statistics. A town might have high numbers in residents but once you look around it you might discover that some plotowners havn' t been on for ages (in some cases owners of only halffinished buildings that are now merely unfinished ghostplots). So the number of residents is not necessarily a sign for a very active community.
And for wealth you should also take in account 2 other factors. First the number of outposts, each outpost costs 50k. A town that has invested in 8 outposts for the residents to use has 400k less than a town without outpost. These 400k are not in the statistic but unlike the dead money in the bank the residents can already benefit from this money (in form of the outposts).
The second point to see in regard of a towns wealth is the financial reserve in form of the Mayors and TA' s wealth and their willingness to donate money for the town. TA's with lot of nbz and the willingness to donate mean that a town has much larger reserves than the statistic might show on the first glance.
As for the list that started the topic. That list is indeed a little short (btw. Buckfast_abby was renamed a while ago). If that is all you have seen so far you are missing quite a bit of the server so far. You might want to consider making a /town list roundtrip as one of your future honeymoon-trips.
