parishes. The Settlement Laws allowed strangers to a parish to be removed after 40 days if they were not working, but the cost of removing such people meant that they were often left until they tried to claim poor relief. In 1697 Settlement Laws were tightened when people could be barred from entering a parish unless they produced a Settlement certificate. Effect on the labour market The Act was criticised in later years for its distortion of the labour market, through the power given to parishes to let them remove 'undeserving' poor. Another criticism of the Act was that it applied to rated land not personal or movable wealth, therefore benefiting commercial and business interests. Cost The building of different types of workhouses was expensive. The Workhouse Act of 1772 allowed parishes to combine and apply for a workhouse test, where conditions were made worse than those outside. The Act stated that workhouses, poorhouses and houses of correction should be built for the different types of pauper. However, it was not cost-effective to build these different types of buildings. For this reason parishes such as Bristol combined these institutions so that the profits paupers made were plunged back into the maintenance of the system. Reliance on the parish The system's reliance on the parish can be seen as both a strength and a weakness. It could be argued it made the system more humane and sensitive, but a local crisis such as a poor harvest could be a great burden on the local poor rate. Variation from the system The 18th-century workhouse movement began at the end of the 17th century with the establishment of the Bristol Corporation of the Poor, founded by act of parliament in 1696. The corporation established a workhouse which combined housing and care of the poor with a house of correction for petty offenders. Following the example of Bristol, twelve more towns and cities established similar corporations in the next two decades. Because these corporations required a private act, they were not suitable for smaller towns and individual parishes. Starting with the parish of Olney, Buckinghamshire in 1714, several dozen small towns and individual parishes established their own institutions without any specific legal authorization. These were concentrated in the South Midlands and in the county of Essex. From the late 1710s the Society for the Promotion of Christian Knowledge began to promote the idea of
