Population centers

[Davin]

I don't see a problem using new/different map symbols for different types.  I'm sure we can come up with something similar to the symbols we have now.

BTW, I got this definition of a "village" from National Geographic:

A village is a small settlement usually found in a rural setting. It is generally larger than a "hamlet" but smaller than a "town". Some geographers specifically define a village as having between 500 and 2,500 inhabitants. 
 
In most parts of the world, villages are settlements of people clustered around a central point. A central point is most often a church, marketplace, or public space. A public space can be a open space (sometimes called a village green), or developed square (sometimes called a plaza or piazza). This type of village organization is called a nucleated settlement. 
 
Some villages are linear settlements. They are not clustered around a central public space, but around a line. This line can be natural, such as a river bank or seashore. (Fishing villages are often linear settlements.) Linear settlements can also develop around a transportation route, such as a railroad line.

So perhaps we can have Hamlets, Villages, Towns, and Cities (and perhaps even a Metropolis, such as ancient Rome, for something extra-large like the Preserve-class settlement?) as our base sizes (increasing from left to right), and we can define population size ranges for each of them?

And here's another nice feature of the new system...  the new mapper allows me to combine symbols together, so we can create symbols for light, medium, and heavy defensive structures and overlay them on (surrounding) the settlement type symbol, so any settlement type can end up with any type of defensive structure, directly on the map.  What do you think about that idea?
