So I was always intrigued by the fact that pop needs are given without a unit. It says 1 Wool in the farmer.txt but it doesn't say how many per farmer. I was trying to calculate that and I found that it varies depending on whether or not the country is civilized. For a civilized country the needs in the various poptype files are the amount needed for 150,000 pops for an unciv it's the amount needed per 250,000 pops.
