Abstract: | Starting from the position that the source of definitions of social need must be examined, the paper suggests that it is also of value to analyse the sequential process through which a series of judgments about need is made by both consumers and providers of services. A framework is suggested by which the relationship between source and sequence of need judgments may be explored, and the factors influencing them identified. This framework is also used to clarify some ambiguities in the use of the term ‘need’, and to consider some implications for need studies. A consensus definition of need is offered in the light of this discussion. |
