The correct answer is: d) All of the above
Sikkim’s HDI is 0.737, which is higher than the HDI of all other northeastern Indian states (except for Mizoram) and is comparable to that of some small mountainous countries, such as Bhutan and Nepal. However, it is still lower than the HDI of highly developed nations, such as Japan and Singapore.
The Human Development Index (HDI) is a composite statistic of life expectancy, education, and per capita income indicators, which are used to rank countries into four tiers of human development. A country’s HDI value is a normalized average of its scores on the three indicators. The HDI was developed by the United Nations Development Programme (UNDP) and is published annually as part of the Human Development Report.
The HDI is a valuable tool for assessing the progress of human development over time and for comparing the level of human development among countries. It is also used to identify the areas where countries need to focus their efforts to improve human development.
The HDI has been criticized for its focus on economic factors and for its neglect of other important aspects of human development, such as gender equality and environmental sustainability. However, the HDI remains a widely used and respected indicator of human development.
