Thirdly, they must be accompanied by specifications of appropriate standards with which their observed values could be com­ pared. Those standards should express both minimum acceptable levels and target levels to be reached at specified future dates. C. IMPROVEMENTS IN THE DATA BASE AND IN ANALYTIC TECHNIQUES 121. The Group agreed that individual countries should not try to adopt a single uniform system of social indicators at this time. Rather, the Group recognized the need to proceed incrementally towanl im­ plementation of data collection efforts and the construction of needed social indicator measures within a broad framework of common con­ cepts, definitions, and coverage specifications as detailed in the general guidelines provided by United Nations recommendations. It was re­ cognized that those common concepts and definitions, together with 30 recommended principles of disaggregation, must be adapted to• reflect local conditions and particular national objectives and priorities. 8 122. The Group expressed concern at the limited utility of current national practices in the field of social indicator reporting, wherein arrays of descriptive social statistics, selected and organized to represent current status and emerging trends in major areas of social concern, were presented in summary form. It was recognized that such descrip­ tive data sets could provide valuable background information, but that they could not offer guidance to policy-makers and programme planners with respect to either the determinants of observed conditions or the consequences of particular policies and programmes. The Group noted, therefore, the need to encourage further attempts at developing data collection procedures that would permit more systematic analysis of the relations among the major segments of socio-economic pheno­ mena, such as the associations between health, education and employ­ ment, or between unemployment, underemployment and various forms 
analysis: The text appears to be discussing the development and improvement of social indicators, which are used to measure social and economic phenomena. The text highlights the need for standardized data collection and analysis techniques, as well as the importance of considering local conditions and national priorities. The text also mentions the need to develop data collection procedures that can analyze the relationships between different social and economic phenomena. Given these themes, it is likely that the text is related to the field of social sciences, particularly in the areas of development, education, and employment.
