Indicators are usvially derived from several chief sources, including: (a) population, housing and agricultural censuses; (b) household sample surveys; (c) civil registration and other registers; (d) administrative data; (e) non-govemmental administrative data. 13/ In more issue-specific terms, WHO suggests the following sources for obtaining data concerning health: (a) vital events registers; (b) population and housing censuses; (c) routine health service records; (d) epidemiological surveillance data; (e) sample surveys; (f) disease registers; (g) other sources of data (including data from sectors other than health). 14/ 25. As these typical sources of indicators reveal, qualitative distinctions are only rarely emphasized and often cannot be significantly derived from existing methods of collection and assumptions surrounding social and economic indicators. Yet the qualitative elements of economic, social and cultural rights are as crucial as those measuring quantitative aspects. The importance of developing a balanced approach, utilizing both quantitative and qualitative forms of measurement, was recently recognized at the Global Consultation on the Realization of the Right to Development as a Himian Right. Regarding the right to work, the Consultation indicated the imperative of examining issues such as the quality of work, worker control and subjective elements of satisfaction and empowerment (E/CN.4/1990/9 (part III), pp. 7 and 8). Applying traditional quantitative indicators to qxialitative issues such as these may require new approaches within the human rights domain, approaches which human rights bodies and experts may be in a good position to develop. 26. Indicators used towards the realization of economic, social and cultural rights must, in addition to providing measurements for overall development and other criteria, also be disaggregated for a variety of groups in society.
