The Human Development Index
(HDI)
The
HDI is a summary composite measure of a country's average progress in
the three fundamental areas of human development—health, knowledge, and
standard of living—is measured by the HDI, a composite summary index. It gauges
how well a nation generally performs in three areas of human development:
1-
A life expectancy at birth that is long and
healthy.
2-
knowledge, as determined by the average number
of years of schooling and the anticipated number of years.
3-
GNI per capita in PPP terms in US dollars
indicates a respectable standard of living.
The HDI establishes "goalposts"—minimum and
maximum values—for each dimension and then displays where each nation stands in
relation to them. As a number between 0 and 1, this is described. Human
development is a measure of a nation's economic progress.
Repercussions and implications
The HDI is used to draw the attention of decision-makers,
the media, and nongovernmental organisations and to shift the emphasis from the
standard economic statistics to human consequences. It was developed to once
again underline that, rather than economic growth, the most important factor in
determining a nation's level of development should be its citizens and their
capacities.
The HDI is also used to examine national policy decisions
and see how two nations with comparable wealth per person can have such
disparate levels of human development. For instance, two nations may have
comparable incomes per person but vastly different life expectancies and
literacy rates, resulting in one nation having a significantly higher HDI than
the other. These differences encourage discussion of health and
education-related government policies to ascertain why what is possible in one
country is out of reach in the other.
The HDI is additionally used to draw attention to variations
between nations, provinces, or states, as well as between genders, ethnicities,
and other socioeconomic groups.
General formula Index = (actual value) - (minimum value)
/ (maximum value) – (minimum value).
