Agricultural vs hunter-gatherer tradeoffs?
(Back in the day before trade was more available for other goods) Someone farming will usually be able to produce more food (calories) and have larger families, but their diet will generally be less varied (and thus less healthy) and their crops are susceptible to diseases.
They are also living closer to one another, so disease can spread among them also
