Pronunciation: [ˈi] (IPA) 
The abbreviation "IDH" is often used in medical jargon to refer to isocitrate dehydrogenase, an enzyme that is important in cellular metabolism. The spelling of "IDH" is straightforward, with each letter representing a distinct sound. In the International Phonetic Alphabet (IPA), the word is spelled /aɪ diː eɪtʃ/. This breaks down to the sounds of "a" as in "eye," "d" as in "deed," "i" as in "eight," "eɪ" as in "ate," and "tʃ" as in "hatch."
IDH, also known as the Human Development Index, is a composite statistical measure that is used to quantify and compare levels of human development in different countries. It was developed by the United Nations Development Programme (UNDP) in 1990 as an alternative to solely relying on income or economic indicators to measure human well-being.
The IDH takes into account three key dimensions that contribute to human development: health, education, and standard of living. These dimensions are measured using specific indicators. Health is assessed through life expectancy at birth, education through the average years of schooling and expected years of schooling, and the standard of living through the Gross National Income per capita.
The IDH is formulated on a scale that ranges from 0 to 1, with 1 being the highest level of human development. A higher IDH value indicates a higher level of well-being and development in a given country. By considering multiple dimensions and indicators, the IDH aims to provide a more comprehensive and holistic assessment of human development than a single indicator or economic measure would be able to offer.
The IDH has become a widely used tool in comparing and tracking human development across countries over time. It helps policymakers, researchers, and organizations to identify areas for improvement and formulate strategies to enhance human development globally.
