Sheffield's growing industry made some people rich. To escape the polluted atmosphere of the centre, they built new houses in the quieter, more pleasant areas nearer the western edge of town and the countryside. The new houses were large with surrounding gardens and were maintained by large staffs of servants. The streets were wide and tree-lined.
In contrast, living conditions in the town's industrial areas were poor, with several families living in one building with few facilities. There was always the fear of unemployment as work was often casual and unregulated. If there was no work, there was no food.
