Yup. Besides which, the sewer-line of buildings are destroyable, so that if, say, Carthage has just past 24000 pop. and is still going strong at 6% growth, destroying the sewer buildings is an option, but if you built farms, you're pretty much stuck into seeing your public order plummet due to squalor, exterminating it, and repeating that cycle not a decade later. While this tactic may be effective, I find it somewhat repugnant due to roleplay reasons.

That's why I think the advice about controlling your pop. growth so that you get 0% growth after the 24000 mark is still relevant. But yeah, I did notice that a lot of advice in the guides were obsolete, such as the ones which claim that a half-stack of archers can defend a city against anything.
