Searching internet for anything is not great deal you just need open any of the Search engines and type anything you want to get wired and unexpected result. I did the same by opening one of the search engines to find anything that made me more knowledgeable. The concept was Human Development Index which I studied here is something which I want to you to tell you about.
The Human Development Index (HDI) is an index used to rank countries by level of "human development", which usually also implies whether a country is a developed developing, or underdeveloped.
The Index was developed by Pakistani economist Mahbub ul Haq, Sir Richard Jolly with help from Gustav Ranis of Yale University and Lord Meghnad Desai of the London School of Economics In 1990. The HDI now being widely used in variety of more detailed measures contained in the Human Development Reports.
The HDI combines three basic dimensions:
• Life Expectancy at birth, as an index of population health and longevity
• Knowledge and education, as measured by the adult literacy rate (with two-thirds weighting) and the combined primary, secondary, and tertiary Gross involvement ratio with one-third weighting).
• Standard of living, as measured by the natural algorithm of Gross Domestic product (GDP) per capita at purchasing power parity(PPP) of country.
Methodology
The Human Development Index (HDI) then represents the average of the following three general indices:
• Life Expectancy Index
• Education Index
o Adult Literacy Index (ALI)
o Gross Enrollment Index (GEI)
• GDP Index
If we look at the statistical update 2008 the following are the countries ranking in Human development Index:
1. Iceland
2. Norway
3. Canada
4. Australia
5. Ireland
