Richard Estes describes the background to a previous ISP survey in his books 'The Social Progress of Nations' (1984) and 'Trends in World Social Development' (1988) - see Note 2 below. Estes reflects that the majority of previous cross-national comparative efforts to measure quality of life or social well-being have been impaired by: serious conceptual problems, missing or unavailable data, a worldwide shortage of suitable researchers and statisticians, political tensions and governments' concerns about how the resulting data will be used.
Estes looks at previous work in some detail:
Work by the United Nations on quality of life or 'levels of living' has been biased towards a 'basic needs' approach - the extent to which the most fundamental needs of people are met, irrespective of other factors. The Organisation for Economic Cooperation and Development (the OECD, made up of 24 of the world's richest nations) has for more than a decade been planning to measure well-being within its nations, but has not so far got much beyond establishing the list of relevant social concerns. Morris D. Morris and colleagues at the Overseas Development Council in Washington have developed a Physical Quality of Life Index (PQLI) measuring infant mortality, expectation of life at birth and rates of adult literacy, but these mainly reflect only the provision of health and educational services. Studies on subjective feelings of human well-being have nearly all been on Western subjects. Estes posits the 'relative non-transferability (that is, non-equivalence) of basic psychological concepts from one culture to another' and that the interpretation of 'happiness' or 'satisfaction with life' differs among people living in entirely different societies.
The newly created 'Human Development Index' formulated by the United Nations Development Programme (UNDP), according to Estes, reflects many of the same limitations as earlier efforts: the number of factors included in the index is too limited given the intent of the index (ie like the Physical Quality of Life Index, the Human Development Index contains only three items) and continues to place more emphasis on economic rather than social development.
Richard Estes' own approach in developing his Index of Social Progress was to use available data from a variety of sources to measure and aggregate 46 different factors for each nation:
- School enrolment ratio, first level;
- Per cent grade 1 enrolment completing primary school;
- School enrolment ratio, second level;
- School enrolment ratio, third level;
- Per cent adult illiteracy;
- Per cent GNP in education;
- Rate infant mortality per 1,000 liveborn;
- Population in thousands per physician;
- Life expectancy at 1 year;
- Under 5 years child mortality rates;
- Per capita daily calorie supply as % of requirement;
- Per cent children immunised at age one, DPT;
- Per cent children immunised at age one, Measles;
- Female life expectation at birth;
- Female adult literacy rate;
- Per cent married women using contraception;
- Maternal mortality rate per 100,000 live born;
- Female primary school enrolment as per cent of males;
- Female secondary school enrolment as per cent of males;
- Military expenditures as per cent of GNP;
- Per capita GNP in dollars;
- GNP per capita annual growth rate;
- Real GDP per head;
- Average annual rate of inflation;
- Per capita food production index;
- External public debt as per cent of GNP;
- Total population;
- Crude birth rate per 1,000 population;
- Crude death rate per 1,000 population;
- Rate of population increase;
- Per cent of population under 15 years;
- Per cent of population over 60 years;
- Per cent arable land mass;
- Natural disaster vulnerability index;
- Average annual deaths from natural disasters per million population;
- Violation of political rights index;
- Violations of civil liberties index;
- Composite human suffering index;
Each of the above factors is given a plus or minus sign, depending on whether more or less of it contributes towards or diminishes social progress. Estes used the Universal Declaration of Human Rights to help identify the types of humanistically orientated factors to be included in his Index of Social Progress.
Estes' research survey results were rather ridiculed in the British press when first published in 1986. Thus a Times leader (17/9/86) asserted: 'Professor Estes is clearly in need of something better to do. Can anyone plumb the quality of life without taking into account the weather, the food and the wine? Can anyone really assess, in mathematical or any other terms, the value of living in Britain? The very faults which lose this country points in any theoretical league of happiness reflect a sense of freedom which Britain still manages to instil in its inhabitants.' And the Daily Mail (20/9/86), in a report on his placing of Denmark at the top of the list, commented that the Danes 'consume more tranquillisers than anyone else on earth, and have the worst psychiatric problems. Violent crime, drug abuse and alcoholism have all doubled in the last ten years. The welfare system is mainly needed to help those who crack up under the strain of paying for it.'
