Populations depend on the 'demand' for them. People flock to the Free City when there are jobs. Jobs for lower class people depend on prosperity and the need for labor from other classes. They compete with slaves for work.
More elite citizens require their own slaves and will cause the population of slaves to increase as they move in. FS and policies will impact how many slaves they desire and how productive they are. The PC's menials also compete for labor within the arcology. Slaves can now 'expire', speed depends on FS and policies. Default lifespan for menials is an average of ~4 years. */
