The Human Development Index (HDI) has been designed by the Indian Government's Ministry of Tribal Affairs to assess the overall development of Particularly Vulnerable Tribal Groups (PVTGs), of which there are 28 lakh in India. Here are the key points worth noting about the HDI designed by the Centre for PVTGs:

• The HDI aims at monitoring the socio-economic development of PVTGs and is calculated based on three indicators: health, education and standard of living.
• The health indicators include infant mortality rate, maternal mortality rate, and age-specific mortality rate while the education indicators include dropout rates and literacy rates.
• The standard of living indicators include access to basic amenities like water, electricity, housing, and sanitation facilities.
• The HDI is intended to provide a comprehensive picture of the development and well-being of these vulnerable groups and to help policymakers formulate targeted interventions to address their needs.
• The Ministry of Tribal Affairs has also launched various schemes and programmes for the upliftment and development of PVTGs to improve their HDI scores and overall quality of life.
• The HDI designed for PVTGs is a significant step towards ensuring that these marginalized communities are not left behind in India's development journey.

In summary, the Human Development Index designed by the Centre for PVTGs is a tool to evaluate and monitor the development of vulnerable tribal groups in India, with the aim of improving their socio-economic status and overall well-being.
