  • 1. 1 DEPARTMENT OF ARCHITECTURE AND REGIONAL PLANNING INDIAN INSTITUTE OF TECHNOLOGY, KHARAGPUR HUMAN DEVELOPEMENT BEYOND HDI SUBMITTED BY- ARUN C BABU 12AR60R09 MCP FIRST YEAR (2012-14) Human development beyond HDI
  • 2. 2 ABSTRACT The well-known Human Development Index (HDI), created by economist Mahbub ul Haq, followed by economist Amartya Sen in 1990, encompasses only three basic aspects of human welfare - life expectancy, education, and income. This paper aims to go beyond this, by identifying more categories of human development, propose plausible candidates as indicators of these categories. This paper suggests that a full assessment of human development requires a much broader set of indicators than the HDI alone. The HDI (and the other two broad indicators) are shown to be worse indicators of the extended categories of human development for OECD countries than for developing countries. Furthermore the key changes made in the 2010 human development report are discussed. The indicators considered for HDI calculation, how the criticism is taken in to consideration etc.. are discussed.

  • 4. 4 1. INTRODUCTION Human Development (HD) goes well beyond the Human Development Index (HDI), with which it is often equated. Human Development can be defined as „a process of enlarging people‟s choices. The most critical ones are to lead a long and healthy life, to be educated, and to enjoy a decent standard of living. Additional choices include political freedom, guaranteed human rights and self-respect‟ (HDR 1990, p. 10). The HDI itself is thus a reductionist measure, incorporating just a subset of possible human choices. It only considers life expectancy, education, and income. It has long been recognized that the HDI is, therefore, a very incomplete measure of HD, leaving out many aspects of life which are of fundamental importance. Since its introduction in the first Human Development Report in 1990, the Human Development Index (HDI) has attracted great interest in policy and academic circles, as well as in the media and national audiences around the world. Its popularity can be attributed to the simplicity of its characterization of development - an average of achievements in health, education and income – and to its underlying message that development is much more than economic growth. Yet the HDI‟s very simplicity prompted critiques from the start, with some contending that it was too simplistic, while others who accepted its self-imposed limitations still questioned its choice of indicators and its computational methodology. One significant flaw of the HDI is that the three variables, which are income, knowledge and G.D.P, are confounding. This means that they are inter-related with one another. For example, the higher the level of education, the more likely the country will have a higher G.D.P. This means that it is hard to tell which of the factors influenced the level of development of a country the most. Another weakness of the HDI is that it does not show the variations of data within a country. Because of this, it is difficult to compare the levels of development for each variable within a country. Moreover, the data is sometimes not helpful in getting useful feedback on how to improve an aspect of a country. For example, a country may have gotten a score near to 1 for one of the factors, but this doesn't mean that it has no room for improvement. Also, these results are relative to other countries, which mean that it is impossible to know the history of development of a particular country. The ranks are values compared to other countries so each set of data of a country is not significant on its own. Moreover, the index fails to take into account some of the key aspects of development such as gender equality and respect for human rights and freedoms. Another point to note is that of the three components, only the G.D.P is responsive to short-term policy changes. In other words, it is important to consider the development of the two other components over time. One last inconvenience of the index is that not all parts of the world have data for the measurement. Human development beyond HDI
  • 5. 5 2. SOME BASIC DEFENITIONS HDI or Human developement index - measures the income, knowledge and the longetivity of the people in the country. This was designed to give a more comprehensive definition of development, which looks beyond the GNP and the GDP of a country. Income -This is measured by purchasing power parity (PPP). This shows the standard of living of a country. Knowledge - This is evaluated by adult literacy rates and the percentage of children attending school. This represents the quality of education in a country. Longetivity -This is gauged by life expectancy in a country. This allows us to see if the individuals of a country live a long and healthy life. Life expectancy index (Life Expectancy - 25) / (85-25) = Life Expectancy Index Education index (2/3 * ALI) + (1/3 * GEI) = Education Index Adult Literacy Index(ALI) adult literacy rate - 0 / 100 - 0 Gross Enrollment Index(GEI) Gross Enrollment ratio - 0 / 100 - 0 GDP Index log(GDP per Capita) - log(100) / log(40000) - log(100) = GDP Index Human Development Index HDI = 1/3 (life expectancy index) + 1/3 (education index) + 1/3 (GDP index) Human development beyond HDI
  • 6. 6 3. DEFINING THE FULL LIFE, OR A BROAD DEFINITION OF HUMAN DEVELOPMENT. Throughout history, defining what makes for a fulfilled life has been a central theme of philosophers and politicians. Aristotle‟s ethics, for example, was devoted to identifying the conditions needed to achieve eudaimonia, commonly interpreted as „the best life‟ (bostock, 2000, p. 15). Alkire (2002) provides lists produced in 39 attempts to identify what makes for a flourishing life produced over the years 1938-2000. Here we will consider six (see table 1),1 each of which adopts a different philosophical approach and justification: Rawls: identifies primary goods through „deliberative rationality‟. According to The Theory of Justice, primary goods „are in general necessary for the framing and execution of a rational plan of life‟ „following full deliberative rationality, that is, with careful consideration of the relevant facts and after a careful consideration of the consequences‟ (Rawls, revised edition, 1999, p. 359, p. 380). They are derived from „some general facts about human wants and abilities‟ and the necessities of social interdependence. Finnis‟ approach is derived from practical reasoning (Finnis 1980; Finnis et al. 1987) which has a lot in common with „deliberative rationality‟, as it is derived from „critical reflection about the planning of one‟s life‟ (Nussbaum 2000, p. 79); or the „internal reflection of each person upon her own thoughts, reading, imagination and experiences‟ (Nussbaum 2000, p. 39; and see Table 3.2, p. 110- 111). Doyal and Gough’s definition of basic needs is based on the principle of the avoidance of serious harm where harm is defined as preventing people realizing activities which are essential to their plan of life (Miller 1976; Doyal and Gough 1991). Nussbaum’s list, which broadly follows Rawls but is more extensive and detailed, is largely based on „overlapping consensus‟ (a concept developed by Rawls (1993)) as a basis for justice in a plural society) plus intuition as to what is needed to be „truly human‟ (Nussbaum 2000).3 An overlapping consensus is an informed view of what people agree about, even with different overall philosophies or religions. The „Voices of the Poor‟ analyzes of Chambers, Narayan-Parker and others (Narayan-Parker 2000), represent what the poor identify as their needs, based on focus groups of poor people carried out around the developing world. A similar exercise is being conducted by the ESRC Research Group of Wellbeing in Developing Countries (Camfield 2005), in which people are consulted as to what makes for a good quality of life in four countries.

  • 8. 8 The six sets of requirements for human flourishing are not in total agreement, and some emphasize some aspects more than others. For example, Finnis and Nussbaum are quite thin on material aspects, but emphasize non-material aspects such as friendship and emotions, which are left out by Doyal and Gough, and get short shrift from Voices of the Poor. Environmental issues only appear explicitly in Nussbaum; she is the only author to record „respect for other species‟ as a significant dimension. People/societies may or may not choose to promote all aspects identified. Hence, as a starting point, the relevant set of dimensions is the set which includes all elements that have been identified as possible aspects of human flourishing, with the aim of trying to measure country achievements on these manifold dimensions. There are obvious problems with such measurement, including, first, identifying what a good measure of each would ideally be, and then finding what (normally imperfect) measures are available in practice. The latter is likely to vary across societies. To make the measurement issue easier, we first draw up a comprehensive set of broad categories to use as a starting point to search for indicators of achievement. For example, we identify „community wellbeing‟ as an important category of HD; then, as indicators of this elusive concept, we include measures of „crime rate‟, „alcohol use‟, „corruption‟, „orphan rate‟, „AIDS deaths‟, „% in civic associations‟, „trust in others‟, „rule of law‟, „confidence in public institutions‟, tolerance of neighbors and „natural disaster rates‟. It is useful to start with the broad dimensions (shown in Table 1 above), first, because objectives of human development are generally thought of in this way. Secondly, while there may be agreement on these broad categories, there is not necessarily the same agreement on selection of better defined and measurable ways of fulfilling the broad categories. For example, we may agree that political freedom and political participation are important dimensions of HD, but this does not imply a precise form of government and constitution. Thirdly, the best ways of achieving progress in broad categories may vary across countries according, for example, to the level of development or geography. Fourthly, partly for this reason, data availability varies across countries, i.e., each country may have data on some indicators relevant to any single broad category, but not consistency across others. In the light of the efforts to identify dimensions of human flourishing just cited, following broad categories of HD can be proposed: 1. The HDI itself, which includes health, education and a measure of income (i.e., it broadly covers bodily health, literacy and basic aspects of material Well-being). 2. Mental well-being (i.e., an individual‟s psychological state) 3. Empowerment (particularly of the deprived) 4. Political freedom 5. Social relations 6. Community well-being 7. Inequalities 8. Work conditions 9. Leisure conditions 10. Dimensions of security – political (i.e., freedom from political violence or instability) 11. Dimensions of security – economic (i.e., freedom from economic fluctuations) 12. Environmental conditions Human development beyond HDI
  • 9. 9 4. SELECTION OF INDICATORS AND PROCEDURES FOR THEIR USE Ideally, there would seem to be many potential measures for each of the broad categories. In practice, there are difficulties. In the first place, some of the categories of HD are in principle difficult to measure (for example, mental well-being). Some data are based on surveys of performance and some on perceptions of observers, with the latter involving an obvious element of subjectivity. In addition, data are often unavailable, or seriously incomplete, covering only a small sample of countries. Some indices are themselves constructed out of a variety of elements and sources in ways that might be subject to challenge. Thus we should be aware of the limitations and pitfalls of data in this field. The choice of indicators listed here is to a certain extent dictated by data availability. The purpose is to identify a set of indicators which broadly represent the more all encompassing version of HD. We shall, therefore, correlate representative indicators of each category with what we call the three core indicators. These core indicators are those commonly used to assess country performance: HDI, per capita income and under-five mortality rates. The HDI, as noted, represents a reductionist approach to measuring human development, incorporating basic aspects of health, education and material well-being. Income per capita is, of course, the most common way of assessing overall country performance, used in particular by the World Bank, under-five mortality, used by UNICEF as a way of assessing country performance. The indicators include, 1. Mental well-being 2. Empowerment 3. Political freedom 4. Social relations 5. Community well-being 6. Inequality 7. Work conditions 8. Leisure conditions 9. Economic stability 10. Political security 11. Environmental conditions 5. CORRELATIONS WITHIN THE CATEGORIES 5.1 Mental well-being. The mental well-being indicators cover measures of unhappiness, as shown by suicide, lack of adjustment to society as shown by the prison population, and life satisfaction. Of the indicators available, male and female suicide are highly correlated, and neither is correlated with the other variables – i.e., a measure of life satisfaction, unhappiness and prisoners per population. It is therefore not particularly important which we select, but we can choose the male suicide rate because, in most countries, it is larger than the female rate. The other variables – life satisfaction and prisoners – are not significantly related to each other. Therefore life satisfaction, prisoner population and male suicide can be selected as independent indicators of mental well-being. Human development beyond HDI
  • 10. 10 5.2 Empowerment. The empowerment indicators cover various measures of poverty and of the status of females. The $1 a day poverty rate is highly correlated with national poverty rates, the Human Poverty Index (HPI) and the share of girls aged 15-19 years who are married, while the other poverty indices are highly correlated with fewer variables within the category. Therefore, $1 a day poverty rate can be adopted as the indicator for this category. The GEM is highly correlated with female parliamentarians. GEM represents a wider range of female empowerment. The ratio of female to male secondary education is not highly correlated with any other variable, though it is moderately (negatively) correlated with the poverty measures and the rate of teenage marriage, and (positively) with the unmet need for contraceptives. The rate of union density is not correlated with any of the other variables, while unmet need for contraceptives is not highly correlated with other variables in the category. Consequently, we choose the $1 a day poverty rate, GEM and female/male secondary education, the unmet need for contraceptives and union density as representing the empowerment category. 5.3 Social relations This is an area where information is particularly scarce and available samples are small. We have indicators for values placed on friends and family, tolerance for different types of neighbors4, as well as the divorce rate. The crude divorce rate is moderately (negatively) correlated with the importance of families, but there are no high correlations among the variables. We therefore retain all four variables – the value placed on families, value placed on friends and the divorce rate – to represent this category. 5.4 Community well-being AIDS deaths are highly correlated with the rate of orphans. AIDS deaths represent a more comprehensive condition, and are a cause of the high orphan rates and of other problems in society, so it can be chosen as an indicator. The public institutions variable is highly correlated with the rule of law and the rate of corruption. We chose that to represent these two variables, since the latter two were only highly correlated with one other variable. The three variables, rule of law, public institutions and corruption are all highly inter-correlated, with little to choose among them. We choose the rule of law (a World Bank measure of the extent to which agents have confidence in the rules of society and abide by them) as a more comprehensive indicator than the other two. The share of the population involved in natural disasters was not highly correlated with any of the other indicators, nor was tolerance of neighbors. Consequently, we can select AIDS deaths, the rule of law, tolerance of neighbors and the rate of natural disasters as representative of community well-being. 5.5 Inequalities Of the various measures of inequality, GDI (UNDP‟s composite measure of gender inequality) is Human development beyond HDI
  • 11. 11 very highly correlated with happiness inequality. We can select GDI because it encompasses a broader set of variables. While health inequality is moderately correlated with the income, the correlation is not high enough to allow us to eliminate either indicator, as is also the case with rural-urban inequality and horizontal inequality (HI). Consequently, we select the income Gain, HI, rural/urban inequality, GDI and health inequality to represent their category. 5.6 Work conditions We have five indicators of work conditions – the unemployment rate at a recent date, child labor, an index of employment conditions reflecting the regulatory situation, informal employment as a proportion of the total and an index indicating the existence of a minimum wage policy. Child labor is inversely correlated with the unemployment rate, although there are only 12 cases of countries with both sets of data. We can retain unemployment because the indicator is available for a much larger number of countries. However, it is well known that data for this (as well as for child labor) are unreliable and variable, since definitions differ markedly across countries. Since none of the other indicators is highly correlated with each other, although there is a moderate correlation between minimum wage policy and employment conditions, we retain the remaining three variables – informal employment, minimum wage policy and employment conditions – as well as the unemployment rate to represent the work conditions category. 5.7 Leisure conditions We can select six variables in this category – phone availability, internet use, radio use, television ownership, newspaper use per person and cinema attendance. The first five are all highly correlated with each other. We can choose phone availability, because the correlations are highest, and cinema attendance (which is moderately related to the other variables), as our indicators for this category. 5.8 Economic stability Variables chosen because they are likely to cause fluctuations in incomes include the share of manufacturing exports (inversely related), portfolio investment as a share of GDP and fluctuations in the terms of trade. We also include the actual GDP business cycle. Individual economic vulnerability is likely to result from these macro-fluctuations and also from fluctuations in the inflation rate, although individual economic insecurity may be reduced by social security coverage. A high correlation was observed between the terms of trade fluctuations and the share of manufacturing exports in output. Since terms of trade fluctuations are likely to have an immediate effect on many people‟s incomes, we retain it instead of manufacturing exports as a share of total exports. None of the other variables was highly correlated with other variables, although portfolio share of investment and social security policies were moderately positively correlated, presumably because each is higher at higher levels of per capita income. We can therefore select all the other indicators noted above. Human development beyond HDI
  • 12. 12 5.9 Political stability The four indicators in this area are: „political stability‟, a composite index reflecting the likelihood of the overthrow of government compiled by the World Bank; net refugee outflows as a proportion of the population 1998-2002 (from UNHCR); an index of collective violence, including excessive civilian targeting (Marshall); and one for political violence (defined as any type of armed conflict from 1990) (derived from Marshall‟s dataset). Political stability, collective violence and political violence are all highly intercorrelated. We choose political violence since the correlation coefficients are higher than in the other two cases. The refugee flow indicator is only moderately correlated with the other indicators and is therefore retained as an indicator representing this category. 5.10 Environmental conditions There is just one composite indicator for this category, environmental sustainability, produced by the World Economic Forum, Yale Center for Environmental Law and Policy and CIESIN, which will therefore represent this category. HDI alone does not encompass many other important dimensions of HD, even on our rather modest requirements of a 0.6 correlation. For each of the eleven categories, at least one other variable needs to be included in order to assess the overall state of Human Development, and altogether we add 31 indicators.

  • 13. 13 6. KEY INNOVATIONS IN THE 2010 REPORT In 2010, for the twentieth anniversary edition, the Human Development Report undertook a comprehensive review of these critiques and introduced several major changes to the HDI. Though the HDI had been modified before, as summarized in the table below, 2010 was the first time that major changes were made simultaneously to the indicators used to measure progress, and to the functional form used to convert those indicators to a single measure of progress. Until 2010, the HDI had been defined as a simple arithmetic average of normalized indices in the dimensions of health, education and income: HDI = (1/3)*(Hh + He + Hls). Hi denotes the subindex for dimension I, with i={h,e,ls} respectively denoting the health, education and living standards dimensions. Life expectancy (le) and GDP per capita (gdp) were the proxies for health and living standards respectively, whereas the education dimension used two indicators: literacy (lit) and the gross enrolment ratio (ger). The indices were normalized using upper and lower bounds. Thus: Hh = (le-lemin)/(lemax-lemin), He = (1/3)*((ger-germin)/(germax-germin))+(2/3)*((lit-litmin)/(litmax-litmin)), Hls = (ln(gdp)-ln(gdpmin))/(ln(gdpmax)-ln(gdpmin)). The 2010 Human Development Report introduced several significant changes in the HDI. The new formula is: HDI = (hhealth * heducation * hliving standard)1/3 The indices Hi are still normalized indicators of achievements. Life expectancy (le) remains the indicator for the health dimension, while Gross National Income (gni) replaces GDP, and mean years of schooling for adults (mys) plus expected years of schooling (eys) for children now make up the education dimension. Hh = (le-lemin)/(lemax-lemin) He = [((mys-mysmin)/(mysmax-mysmin)) *((eys-eysmin)/(eysmax-eysmin))] 1/2 Hls = (ln(gni)-ln(gnimin))/(ln(gnimax)-ln(gnimin)). Human development beyond HDI
  • 14. 14 The approach introduced in 2010 retains the same three-dimensional structure with equal weights, with several key changes: It replaces the indicators for income and education, it changes the method of aggregation from an arithmetic average to a geometric average, and it redefines the upper and lower bounds used to normalize the index, eliminating the practice of capping variables that surpass the upper bounds. Three of the four variables that go into the HDI were revised. GDP per capita was replaced by GNI per capita (both valued in PPP US$), while literacy and gross enrolments were replaced by mean years of schooling and expected years of schooling. To supplement these changes to the HDI, three new complementary indices were introduced in 2010 that were designed to capture the deprivations and disparities: the Inequality-Adjusted HDI, the Gender Inequality Index, and the Multidimensional Poverty Index. It is worth focusing on the changes related to income. The Human Development Report and its HDI was an explicit challenge to the reigning paradigm of the late 1980s in development policy circles, commonly known as the Washington consensus. The prevailing approach for development economics was best symbolized then in the World Bank‟s World Development Report’s practice of ranking countries by per capita income. Throughout its history, the HDI has effectively pinpointed the differences in rankings that emerge from a comparison between the HDI and per capita incomes. Haq pointed out in 1995 that of the 173 countries included in the HDI rankings, there was no difference between the HDI and per capita income rankings for only four countries, while for more than a third of the sample the HDI and per capita income ranks differed by more than 20 places. These patterns still hold true today. The 2010 Human Development Report systematically explores the links between economic growth and other dimensions of human development and documents the finding that over relatively long periods of time high rates of economic growth are not necessarily accompanied by improvements in other dimensions of human development. 6.1 New indicators to measure human development The 2010 HDI revisions took into account measurement improvements in its three dimensions over the past two decades. Unfortunately, alternative measures that may be conceptually preferable are available for fewer countries than were typically covered by the HDI, and are often not updated frequently. The best example is perhaps life expectancy. The World Health Organization has reported Health-Adjusted Life Expectancy (HALE) for 192 countries, as the number of years that a person might expect to live in good health. The estimates are based on country life tables, analyses of 135 causes of disability for 17 regions of the world and 69 health surveys in 60 countries. However, the WHO does not plan to regularly update its estimates of HALE. Similar problems arose in the case of education, where the cross-national assessments of science, mathematics and reading levels that could be used to construct quality adjustments are only Human development beyond HDI
  • 15. 15 available for a limited number of countries. The approach in the 2010 Human Development Report was to adopt mean years of schooling as calculated by Barro and Lee as the indicator to measure the education of adults. This indicator is more frequent, has broader coverage, and better discriminatory power than literacy. The calculations are based on primary data from the UNESCO Institute of Statistics‟ Database of Censuses and can thus be replicated and updated. Literacy – which had up to now carried a 2/3 weight in the education index – has become deeply unsatisfactory over time as a measure of progress in education. The world average literacy rate rose from 60 to 83 percent between 1970 and 2010. Almost half of countries have a literacy rate higher than 95 percent and, indeed, developed countries no longer collect data on basic literacy. Further, many developing countries are poised to attain universal literacy in future years. While literacy was a good measure to evaluate progress in the past, it is now much less informative. The new HDI also changed its measure of the education of children, replacing the gross enrolment ratio with a measure of expected years of schooling. This captures the average number of years that children today could be expected to attain in adulthood if enrolment rates stay at their current levels. The education indicator is now framed as a measure of years of schooling, with the education of current and future generations receiving equal weights. There is extensive literature today on the drawbacks of GDP per capita as a measure of wellbeing and economic progress, most recently summarized by the report of the Commission on the Measurement of Economic and Social Progress led Joseph Stiglitz, Amartya Sen and Jean-Paul Fitoussi (2009). Some of these criticisms relate to its inadequacy as a broader measure of welfare or capabilities, while others examine its ability to measure an economy‟s capacity to provide goods and services to its people. Most notable among GDP‟s many shortcomings are that it does not measure non-market activity, such as subsistence agriculture or household work; it does not register productivity growth in public goods; it makes no adjustment for the depletion of natural resource; and per capita GDP is often unrepresentative of the typical person‟s actual income. Are all of these criticisms relevant for the income dimension of the HDI? In order to put some of these criticisms in perspective, it is important to consider why income was included in the HDI in the first place. As discussed in the early reports, income differs from health and education in that it is not a direct measure of a capability, but rather an input into these capabilities. The relevant capabilities include adequate nourishment, shelter, and access to participation in the basic life of society. Attaining these capabilities requires people to have command over a basic set of resources necessary to ensure a decent standard of living. In other words, the measure of income in the HDI is a proxy for the typical person‟s command over resources that they can use to acquire goods and services, and save for the future. Note that this is very different from the idea of GDP as a measure of how much an economy can produce. Gross Domestic Product does not include transfers received from other countries, for example, while it does include transfers sent to other countries, as it is meant to capture the goods and services produced within the national territory. But to the extent that one wants to capture command over resources, one would like to include transfers from abroad and exclude transfers to other countries. The new HDI does this by replacing per capita GDP with per capita Gross Human development beyond HDI
  • 16. 16 National Income (GNI), which is equal to GDP less primary income payable to non-residents plus primary income receivable from non-residents. 6.2 Combining achievements into an aggregate measure Perhaps the most radical innovation introduced in 2010 was the shift to a geometric mean in order to aggregate dimensional indices. This marks a significant conceptual change in the way in which one conceives the relationship between different dimensions of capabilities. The shift to the geometric mean addresses the issue of perfect substitutability: This was a problematic assumption of the old formula, in that the level of priority to be given to a dimension was invariant to the level of attainments. The new HDI attains a compromise by adopting a functional form that is between the extremes of perfect substitutability and perfect complementarity. There is a distinct advantage to the geometric mean – unlike the arithmetic mean or other forms of aggregation with a non-unitary elasticity of substitution, the rankings produced by the geometric mean are invariant to the scale in which each variable is measured. Consider the comparison between Japan and France in the old functional form: Japan has a higher life expectancy than France, with a higher education index and also a slightly higher per capita income. With the additive functional form, Japan ranks 6 positions above France. But if we were to change the maximum for life expectancy by 10 years, we see that Japan drops by 2 positions relative to France. This is problematic as thresholds are likely to be continuously updated s the world experiences progress. This problem does not affect the new HDI, however. In the same example but with the new functional form, the relative ranking between Japan and France is unaffected by the choice of maxima, with Japan always occupying three positions above France. The choice of minimum, in contrast, will continue to have significant implications for rankings even in the geometric mean. This makes sense because the minima have a concrete meaning as subsistence indicators – values below which it would be very difficult for a society to survive over time. In the new formula, these subsistence values are derived from the historical and epidemiological literature. 6.3 Addressing other critiques Another concern with the HDI relates to its potential redundancy, given the high correlation of the index with its underlying components. The 2010 Human Development Report addresses this criticism head on, by showing that this criticism is fundamentally unfounded. It explores how the HDI illuminates investigations of advances in human development over time. The 2010 Report argues that the picture of development obtained from looking at the past forty years through a Human development beyond HDI
  • 17. 17 human development lens is vastly different from that obtained through a sole focus on economic growth. To take just one example, China is by far the economy with the greatest rate of economic growth in that period – its annual per capita growth rate of 7.6 percent significantly exceeds not only the world average (1.8 percent) but also that of the second highest growing economy (Botswana, 5.6 percent). But China ranks 64th out of the same 135 countries in terms of average improvement in non-income HDI, and is one of only 10 countries in the world with a lower gross enrolment ratio today than in 1970. More generally, only three of the top 10 fast growing economies for the period of study are also top improvers in the HDI – the majority of countries that get into the list of top HDI performers do so because of their performance in terms of health and education, not income. If one looks at changes over time instead of levels, the redundancy argument disappears. Critics have argued further that the HDI categories that used to classify countries into low, middle and high levels of human development are not robust to data revisions over time. This was because the numerical HDI thresholds used to define these categories (0.5 and 0.8) were kept fixed even after changes in methods and data. This valid criticism was addressed in the 2010 Human Development Report by changing the method used to create country categories. Rather than using fixed thresholds, countries are now grouped by quartiles of the HDI distribution. The problem of change in development groups due to data updates or formula revisions is no longer an issue, because countries are grouped by HDI rank, not value. Some recent criticisms have pointed to “paradoxes” that would arise if a society tries to maximize the HDI. These criticisms are based on the incorrect premise that the HDI is a welfare or utility function. There are at least three reasons why one should not recommend that societies try to maximize the HDI. To begin with, not all elements of human development – such as political freedoms, equity or sustainability - are included in the HDI. Second, the expansion of capabilities is only one of the reasons why people may value the components of the HDI. People may enjoy the luxuries that come from higher levels of income even if these don‟t contribute to them leading substantively different lives. Third, the HDI is severely limited by data constraints, and thus one can at best expect it to give a rough approximation of a country‟s relative development level and progress. Enabling debate The Human Development Reports have always stressed that the HDI is not and was never intended to be a definitive measure of development. By design, the HDI is a simple measure that uses available international indicators (that are inevitably imperfect), that provides a broad vision of the progress of people. The aim is to stimulate discussion and debate, including about the appropriate ways to think about wellbeing and progress. As symbolized by the Human Development Report website‟s introduction of online tools that allow users to construct their own indices with variable weights and indicators, the HDI should be understood as a starting point of a global conversation about development, rather than an endpoint.

Following other contributions in this area, the paper identified eleven categories of HD which seem to encompass all the major dimensions of human development. For each category, then identified a potential set of indicators which seem to be plausible measures and for which data are available. The paper investigated correlations among these measures, and, in order to reduce the number of variables representing each category, included only one indicator for any set of indicators that are highly correlated with each other, also retaining any indicator that does not show a high correlation with the other indicators in its category. The aim was to include only variables which are broadly independent of each other. This paper explored empirical correlations and did not attempt to investigate causality. The basic purpose, however, is not to be definitive but to show that extending the concept and measurement of Human Development to a broader set of dimensions seriously affects the way one should measure and assess country performance. In future work in this area, researchers should intend to identify typologies of developing countries/regions according to their success or failure with respect to the different dimensions of HD and relate this to potential policy choices. To the extent that data are available, we would also like to trace the historical progress of the current OECD countries in the various categories, which may help in drawing conclusions about transitions over time.
