Human Development Index (HDI) is an important tool to measure the progress of countries in providing a better standard of living to their citizens. It is a composite index that takes into account several factors, including life expectancy, education level, and income. The HDI helps in assessing the impact of policies and programs that are designed to improve the well-being of people. For PVTG (Particularly Vulnerable Tribal Groups), who are the most disadvantaged groups in the Indian society, the HDI provides a framework for evaluating their progress in terms of human development. The objective of designing an HDI for this group is to identify the areas where they are lagging behind the rest of the population and to develop policies and programs that can help them catch up. The importance of an HDI for PVTG population can be evaluated as follows:

• It provides a comprehensive measure of their well-being beyond just income, which is particularly important for PVTG groups who often do not have access to traditional forms of employment and income.
• It helps in identifying the specific areas where interventions are needed, such as education, healthcare, and access to basic amenities.
• It enables policymakers to monitor the impact of their programs and policies that are designed to improve the well-being of PVTG population.
• It helps in prioritizing resources and targeting interventions to those areas that need it the most, thus making the policies and programs more effective.
• It helps in raising awareness about the challenges faced by PVTG population and in advocating for their rights and well-being.

Overall, an HDI for PVTG population is a crucial tool for promoting inclusive human development and reducing inequality in society.
