Going by sustainability criteria of development and environment, who is a “Tribal”?

Over the last couple of weeks leaders, anchors, reporters, commentators and critics, no one had mentioned Madam President Droupadi Murmu without pointing "tribal" as if that is her identity and credential. By that what is that they are referring or reminding about? Is it her remoteness from New Delhi? Or, is it about not having access to a school with government prescribed text books? Or, is it about marginalisation of vulnerable groups who are deprived or denied their basic rights and natural justice? To me it appears that most of us continue to be stereotyped and out fashioned about development and even democracy or poverty (economic) and backwardness (physical). What Madam President spoke after swearing in should make us ponder where we are heading in the name of heights of development and depths of democracy. That is what prompted me to share my thoughts in this context.
