The Centre's plan to design a Human Development Index (HDI) for Particularly Vulnerable Tribal Groups (PVTGs) could potentially revitalize the focus on development for these groups. Here are a few points on how this could happen:

• The HDI will provide a comprehensive picture of the development status of PVTGs, which will help in identifying the areas that need improvement.
• This exercise is expected to generate robust data, which will be useful in formulating and evaluating policies related to the welfare of PVTGs.
• The HDI can be used as a tool to monitor progress and identify disparities between PVTGs and the general population.
• The HDI will also factor in indicators that are specific to the needs and realities of PVTGs, such as forest dependency and traditional livelihoods.
• The exercise can also help in mobilizing support and resources towards the upliftment of PVTGs.

Overall, designing an HDI for PVTGs can be a crucial step in addressing the development challenges faced by these communities.
