Anotations

Scope note:

Communities of modest size, built mostly since the Industrial Revolution, in which the primary employment is in factories. When the primary employment is in factories for the manufacture of paper, steel, or textiles, use "mill towns." When settlements are purposely built by factory owners to attract workers to isolated locations, use "factory villages."
