Designing a Human Development Index (HDI) for Particularly Vulnerable Tribal Groups (PVTGs) can have significant implications for their overall well-being and development. Some potential impacts include:

• Improved understanding of PVTGs: Creating an HDI for PVTGs can help policymakers, researchers, and the general public understand the unique challenges faced by these communities regarding education, health, and other key development indicators.
• Focused policymaking: Having an HDI would enable policymakers to focus their efforts on specific areas that require improvement. Consequently, policies can be designed, making efforts more targeted, result-oriented, and effective for PVTGs.
• Increased accountability: An HDI would hold governments accountable for the fulfillment of basic human rights and PVTGs welfare. It would help people recognize what they deserve and demand it from the government.
• Empowerment of PVTGs: People belonging to PVTGs can be involved through the HDI within the planning and decision-making process and hold their leaders accountable.
• Recognition and Representation: Designing HDI for PVTGs will bring recognition and representation to their indicators and needs.

Overall, designing an HDI would help governments, institutions and NGOs to focus on critical issues and adopt appropriate policies, development programs, and assist in bridging the gaps between PVTGs and mainstream development.
