I don't think I've encountered anyone doing much more than casual observation on the subject, so I'm considering making a sandbox map and recording the population and worker percentage over the course of 200 years or so. Perhaps making a city of 100 fancy residences, then once the city hits 9,200 (which is to say, all houses full), record the number of people in the workforce every year. The goal would be to remove disease, immigration, and every other potential factor that could affect the percentage of a population in workforce, so that the effects of an aging population could be observed in total isolation. My only concern is difficulty, because it's known that in Zeus, toggling the difficulty affects how many people are in the workforce. Is this known to be a factor in Pharaoh?
Edit: upon further consideration, 30-40 FRs is perhaps more reasonable, as that can be done easily in a single block, so that setup time is minimized. Minimal setup time gives the population less time to age before everything is totally stable. Military buildings will be used to soak up excess employees, and via prioritisation will be the first to lose employees as the population ages and worker shortfalls occur.
