I'm not sure, I'd have to see your data to see exactly what you mean.

I think perhaps distance is a factor, but trade income is most definitely affected by population. Absolutely no question - I've seen what happens when you change populations. You lose money from exports, the imports you already get, and you might lose entire import routes. [see example]

Tax: Sorry I misread the original post. Damn my speed reading skills. OTOH, I'm not meant to be 'wasting' time here at all...

Of course, I forgot another geographical restriction on sea trade: you can't sea trade with a settlement you have a land route with! But maybe that was obvious.

Oh, and trade income doesn't seem to be affected by campaign difficulty.

One thing to note: the trade income, as given in the trade summary scroll, is different than the figure given in the Settlement Details scroll. Is this just in my games, or is everyone seeing this? FYI, the corresponding drop in actual income is 7067 to 6165 Denarii.
