Hey dimwit,
There is no prescribed order of building production buildings. Most people go for the most efficient one. How you define "most efficient" will vary from person to person. Some would say that the most efficient buildings are the ones that produce the most supplies in an hour, those buildings tend to take up lots of space and require a larger population (e.g. goat farm, farm, tobacco plantations), so people don't really put many of them, but their high output means that it works out just now, and you only need to click a few times to set all the buildings. Of course, if you get plundered, you lose a lot as well.
Others (myself included) prefer buildings that occupy a small space, and require little population, so many of them can be built (e.g. alchemists, clockmakers). They produce a smaller amount of supplies, and you have to click multiple times to set all of them, in order to get the same total hourly production as the larger buildings above. Being plundered when doing this is less painful, of course.
I would churn out some math, if you wish to see it, but this is what I would say, for now.
Cheers,
L.R.
