text: framework to systematize social indicators. One of the earliest attempts was the UNRISD version of a two level system of social indicators oriented towards developing countries. The Organisation for Economic Co-operation and Development (OECD) version of social concern was defined by a three-tier system of social goals, fundamental social con­ cerns and subconcerns and was oriented toward developed member countries of OECD. The United Nations system of social and demo­ graphic statistics recommended comprehensive statistical series which could be easily converted into social indicators free from any judgement on social values and objectives, but useful for analysis and planning. The OECD version contained a number of subjective indicators while the UNRISD set included none. 4 Raymond A. Bauer, "Detection and anticipation of impact: the nature of the task". R.A.

The frameworks, or combination thereof, described above could be adopted by any nation interested in developing its own structure of social indicators. Social indicators published by developing countries often lacked a structure representing social values and objectives of the nation. The use of statistics from available sources was found to pose a fundamental obstacle to the generation of meaningful statis,tical constructs. To meet the immediate objectives of a social indicator series, a meaningful selection of indicators relevant to the context of development of a,specific country was suggested. 19. Social indicators in the form of indicative statistical series could . be used for both analytical and planning purposes. However, there had been a number of attempts to derive an aggregate indicator of level of living. Such efforts usually ran into the problems of weighting and indexing, as in the case of the UNRISD composite index of well-being. That problem could be avoided by modifying the gross national product 
analysis: The text appears to be discussing the development of social indicators, which are used to measure the well-being of a society. The text mentions various frameworks and systems for creating social indicators, including those developed by the United Nations and the Organisation for Economic Co-operation and Development. The text also discusses the challenges of creating meaningful statistical constructs and the use of social indicators for analytical and planning purposes.
