CHAPTER 1<br />

<strong>Estonian</strong> <strong>Human</strong> <strong>Development</strong><br />

Index and its components<br />

1.1. Global <strong>Human</strong> <strong>Development</strong> Index<br />

The measurement of human development<br />

and the paradoxes related thereto<br />

Today’s rational person is characterized by a desire to quantitatively<br />

measure all kinds of phenomena with the goal of<br />

assessing and comparing them, and also managing and<br />

directing them to change in the desired direction. For this,<br />

however, one must be sure about the direction one wants to<br />

move in. When measuring the development of society, it is<br />

necessary to understand what determines the developmental<br />

level a society or country has achieved. How important<br />

are wealth and the abundance of opportunities? In determining<br />

a country’s developmental level, what role is played<br />

by the population’s perception of the surrounding world<br />

– against the background of a scientific or religious worldview?<br />

Is the sustainability of the population and culture a<br />

precondition for a high developmental level in a country/<br />

society, or is it a consequence? To what extent, are the developmental<br />

level of a society and the quality of life and happiness<br />

of its people related? Is there reason to believe that the<br />

highest possible quality of life of its societal members is the<br />

objective we should to aspire to?<br />

With regards to countries, it has been the custom for<br />

a long time to speak about their developmental level, but<br />

the quantitative scale for measuring developmental levels<br />

is a relatively new phenomenon. Since 1990, the UN has<br />

issued an annual <strong>Human</strong> <strong>Development</strong> <strong>Report</strong>. It has also<br />

included a <strong>Human</strong> <strong>Development</strong> Index (HDI) calculated<br />

for each UN member state and a country ranking based on<br />

the index. According to this concept, the <strong>Human</strong> <strong>Development</strong><br />

Index should measure the opportunities available to<br />

the population of each country, based on the assumption<br />

that an abundance of opportunities is related to a higher<br />

quality of life for the people living in that country.<br />

Every numerical composite indicator is associated with<br />

a statistical paradox: the occurrence of development should<br />

be demonstrated by an increase in the average level, while,<br />

in the case of many indicators, a higher average often results<br />

in greater inequality, indicating the disparity of the society’s<br />

development. Since this disparity results from the processes<br />

actually taking place and the particularities of individual<br />

phenomena and various speeds of development, the<br />

reduction of the inequality of various indicators requires<br />

the implementation of additional resources. Therefore the<br />

higher a country’s average developmental indicator, the<br />

more resources are required to reduce the inequality. Thus<br />

it follows that the guarantee of an abundance of opportunities<br />

is one of the primary assignments of the state for the<br />

support of positively progressing developmental processes.<br />

The calculation of the <strong>Human</strong> <strong>Development</strong> Index is<br />

based on three relatively easy-to-find indicators that characterize<br />

the country’s social and economic situation. These<br />

indicators are:<br />

• Life expectancy at birth, which indicates a population’s<br />

health and longevity;<br />

• Educational attainment, which is indicated, on the one<br />

hand, by adult literacy, and on the other hand, by the<br />

enrolment rate of students at various educational levels;<br />

• Standard of living, which is measured by GDP per capita<br />

at purchasing power parity in US dollars.<br />

A component (index) is calculated on the basis of each<br />

indicator, which is assigned a value between 0 and 1. The<br />

higher the value of the corresponding component, the<br />

higher the level of the corresponding life sphere in the<br />

country is. The HDI is calculated as the average of the<br />

three components (Figure 1.1.1.).<br />

Even though one may be somewhat sceptical about the<br />

<strong>Human</strong> <strong>Development</strong> Index as a whole, because the combination<br />

of its components is not substantively well justified, it<br />

has still turned out to be useful as a comparative assessment<br />
