A factory isn't just "making things", though. There might be semi's coming and going making traffic more dangerous, there could be materials left out that are dangerous to kids if they wander through the wrong fence, maybe there'll be loud noises that are detrimental to kids' concentration during tests.

There's plenty of reasons industry is usually put outside of towns.
