Bradshaw (1972) distinguishes two other categories of need: felt need and expressed need.
The terms are fairly self-explanatory; felt need is what people feel they must have, and
expressed need is a strongly expressed want. The distinction between them is that a person
can feel a need without telling other people about it - people are sometimes reluctant to
claim services because of fear, apprehension or stigma - and it is possible to express a need
without feeling it. Unlike normative and comparative concepts of need, these categories
are formed by the people in need themselves.
