Colonization configuration files seem to contain some extra buildings (like "Capitol") costs of free buildings (you can remove them only by editing a save file, in normal play every colony has all the free buildings), and size/upkeep data, that serves no obvious purpose.

The population figures are taken from DOS Colonization's configuration file names.txt I remember something about certain buildings (Cathedral) having different requirements in other versions.

It's worth noting that you can construct building with population requirements higher than what your colony has by temporarily transferring colonists into the colony, starting construction, and then transferring the colonists back out. The building will still finish. This can be helpful if lack of rebel support would otherwise force you to wait several turns to make another colonist slot available.
