The 1861 census identified that 1,032 residents of Stourbridge were involved in the glass trade in some way. Of these, 541 were glass workers - an increase from 409 in 1851, believed to be partly caused by the collapse of the glass industry in nearby Dudley in the 1850s. The vast majority of those involved in the glass trade came from Staffordshire, Warwickshire, Worcestershire and Shropshire. 9% came from other parts of England and 0.2% had come from abroad. Of particular note are glass cutters, as 8.1% had come from Ireland, believed to be as a result of the decline of the Irish glasscutting industry in the first half of the 1800s. The houses inhabited by glassworkers were of a much better quality in comparison to the slums in which the nailmakers of Lye and Wollescote lived. However, only a few glassworkers owned their own houses.
