User blog comment:RemosPendragon/Imperial Worlds - Tithes and stuff/@comment-24579946-20150531184705

I always believed that the tithe grades took all produce into account, be it food, munitions, psykers or men for the Imperial Guard.

In any case, that you have done a great job with this post, and that it would be pretty accurate if you bumped the Fortress World numbers up a bit.

I think though that it would be worth taking other things into consideration as well, including "modifiers" for population (an agriworld with 1billion inhabitants may not produce as much food per capita but they would be able to provide men to the Imperial Guard), and for past history (I think Vostroya have a greater tithe rate than they would normally, as well as providing every first son to the IG, because of their rebellion in years past). Possibly to for genetic purety : you can imagine ab-humans or populations with more mutants would have more taxes, because that's what the Imperium's like.
