As far as I know, it was only the Spartan citizens that were subjected to infanticide, brutal training, compulsary service in the army, and forced living in barracks. The commoners in this society could basically do what they wanted. They were the ones that actually held property, I think. The citizens had the privilige of running the government, and the responsibility of defending it; I don't think they were allowed property though.Kahuna Burger:
I would take the normal spread for a city. Then kill off everyone with a con under 12. Yes, this will give you a smaller population, the spartans didn't have big numbers, they had tough cookies. Next make everyone with a str or con less than 13 a commoner.
