Locations and starting sizesEdit
Your first city has its position fixed by the program (though you may determine it if you start on an edited map), and its size always starts at a population of 4. With a random map your capital is always on a plain and usually has two already-irrigated plains in its radius. (See File:C-evo-badrandomstart.png for one that did not!)
You have no initial say in the naming of cities unless you edit the relevant "tribe.txt" file (which is not hard to do). The default names are a selection of 40 or more cities per nation, not always in any logical order and sometimes not matching real-world names (notably by the omission of accents).
You can change the name, however, using a right-click on the city name on the F3 menu or the turn-end events list.
Production and policingEdit
The central tile of any city produces whatever food and material the terrain offers, but instead of trade it produces four morale points.
The remaining members of the population can be police (each contributing two morale points) or can work other tiles (among the nearest 20) for whatever food, material, and trade are available.
Each city can have one of almost every available building; the main exception being that a city with no "coast" (water) tile adjacent to its central tile cannot have water-related buildings such as harbor, but it can have a dockyard (to help repair ships that can use a canal to reach water).
The bottom left panel of the city screen toggles between "Units supported" and a "map" of buildings that are present (shown in black) or are being built (shown in red, which may disguise the fact that the building will replace a lower-level building of similar function). See layout of buildings.
To grow beyond 8, a city needs an Aqueduct. To grow beyond 12, it needs a Sewer System. (When you build the latter, the former is automatically sold.) Ultimately there is no other limit. However, every occupant consumes two units of food per turn (and some ground units use food too), whether or not he or she is producing anything on one of the 20 available worker-tiles. (The only situation in which you need not worry about food is if you are using the option on the "Manipulation" menu that has every city growing each turn; in that case, a city that is risking starvation merely stays at the same size for next turn and its food "accumulation" can be negative.)
