I'll add gold mining, aswell as gold importing to the NS.Yes, gold coating is of an important issue, gold is the mineral of the Emperor, therefor, since the Holy Legion is essentially the honor guard aswell as Royal guard of the Emperor himself they are coated in the stuff to look as majestic and Royal as possible, there's also a couple religious reasons.
I took the plague into account when numbering the cities of the Imperium, I wanted it to be a large empire and simply because of it's large population disease and plagues would be a problem, which is exactly what I planned. But if you wish for me to make the city population smaller then I will do so.
It's not so much the why but the how. If you've added gold mines, that's fine.
Yes, the population in the capital needs to be much lower. About 500,000 people is pushing it. 2.5 million is just too much.
Remember that rhe population will live in towns and villages too. You don't need to list every settlement, just the important ones.
