There are two types of adults in Banished, Laborers and Workers.
A Laborer is a general worker that can go out and gather basic resources from the land (wood, stone and iron). They are also responsible for carting around resources from certain locations to others though I am a bit less clear on this.
A Worker is someone who has been given a specific type of task to do like fish, mine, teach or farm. As long as the materials they need are available to do their work they will keep at their specified task. When there are not enough materials however they seem to revert into being just a laborer again. The easiest example I have seen of this is a farmer during the winter will go around and gather stone and wood like the other laborers.
Now another thing a laborer is supposed to do is move resources around, thus allowing your workers to keep on working when they need to. What is a good ratio of laborers to workers to try and keep my workers from wanting for resources? Or is the ratio more along the lines of laborers to resource production areas (buildings)? I am looking for a general field park number of people not to send off to a specific task.
I have seen it mentioned in other questions and answers that you need to have laborers to keep the materials moving around and I am wondering what is a good worker to laborer ratio? 1 to 10? 1 to 5? 1 to 20? I am unsure. I have seen a blacksmith not be able to make steel tools because I can not get the coal away from the mine that is maybe 12 blocks further away than where the iron comes from.
