text: conditions in quantitative form was recognized, but the Group also stressed the fact that some important aspects of the several areas of social concern could not be expressed purely in quantitative tenns, given the current state of the art. (2) The Group recognized that quantitative measurements of selected aspects of different areas of social concern must be accom­ panied by interpretive commentary that would bring to light their significance in terms of the particular historical, social, and cultural environment in which they were embedded. (3) The Group also recognized the need for summary aggregative measures that would provide policy-makers, planners and the general public with an overview of prevailing social conditions. But it recognized too that in constructing such aggregate summary measures, it would be necessary to employ essentially arbitrary weighting procedures in order to incorporate a number of particular social indicator measures in a combined summary index. Given the sensitivity of those aggregate measures to both the individual measures selected for their composition and the weighting assigned to each component, the Group recommended that all such aggregate indicators should be accompanied by explicit accounts of the procedures whereby they were constructed. ( 4) The Group stressed the importance of developing a set of social indicators on. the basis of an a~essment of the observations and measures called for in monitoring the different areas of social concern, regardless of the current availability of the requisite data. That was essential in order to reveal gaps in the information system and to devise strategies for developing appropriate data collection efforts on the basis of individual administrative and research priorities. 33 Annex I LIST OF DISCUSSION PAPERS SUBMITTED TO THE EXPERT GROUP 1. "Social indicators: definition, purposes and development" by Hackchung Choo (reproduced as annex II) 
analysis: The text discusses the development of social indicators, which are metrics used to measure and track social conditions. The indicators are intended to provide a comprehensive overview of social conditions, and the group emphasizes the need for interpretive commentary to contextualize the data. The text also highlights the importance of developing a set of social indicators to monitor various areas of social concern, regardless of the availability of data. Given this focus on social conditions and indicators, it is likely that the text falls under the categories related to social sciences.
