In the United Kingdom, the word 'hamlet' has no defined legal meaning, although hamlets are recognised as part of land use planning policies and administration. A hamlet is traditionally defined ecclesiastically as a village or settlement that usually does not have its own church, belonging to a parish of another village or town. In modern usage it generally refers to a secondary settlement in a civil parish, after the main settlement (if any). Hamlets may have been formed around a single source of economic activity such as a farm, mill, mine or harbour that employed its working population. Some hamlets, particularly those that have a medieval church, may be the result of the depopulation of a village. The term hamlet was used in some parts of the country for a geographical subdivision of a parish (which might or might not contain a settlement). Elsewhere, these subdivisions were called ‘townships’ or ‘tithings’.
