Are students considered as adults or as children for reproducing in Banished

Build a 20x20 pasture and allow it to fill to the max with animals. Set both workers to work on it. Basically the more animals the faster they breed.

A few facts to consider:

• Students graduate at age 16 if they live next to the school. If they have to walk (back and forth) to the school, that walking time does not count toward education progress. This is why players are reporting 20 year old students.

• Education gives the worker a ~50% productivity increase. However, education does not make a worker walk faster. This means that hunters, gatherers, foresters, laborers, vendors and tradesmen do not benefit much from education. Fishermen, miners, quarrymen, firewood cutter, blacksmith and tailor all benefit from education.

• Having students locked up in school delays the creation of couples. This could tip a city that's on the edge into stagnation. If you have fewer than 10 children, you should probably be focused more on making more children, rather than education.

• Education also reduces random accident death, so you'll want it eventually.

So, putting it all together, I'd build a school when all of these criteria are met:

• There are more than 10 children.
• There are more than 8 workers in non-walking jobs.
• There are no more pressing needs (food/firewood).
• There are at least 4 spare laborers (+1 to be a teacher) to handle the gap created by the first wave of students.
