The terms Porja and Parja seem to be synonymous. Parji language is identical with Bhatri which has now become a form of Odia. Most of them have migrated from Orissa State about 300 years back to the present habitat in search of cultivable land.
The Porja are a hill tribe inhabiting the Agency Area of Visakhapatnam District, and in adjoining areas of Odisha State. They are chiefly shifting agriculturists and cultivate lands on the high-level hill slopes. A numerically small tribe with a population of 12,600 as per the 2001 census, they reside mainly in the Munchangiputtu, Ananthagiri and PeddaBayaluMandals.
The Porja are mostly illiterate, and children are not encouraged by their parents to attend schools because they are seen as an additional source of family income.
The Porja script is based on their seasonal or semi-nomadic agricultural practices. Traditionally, they farm an area for eight months to two years, but before they move on, they scatter seeds as a final ritual of thanks to Nature. They believe the seeds, and the resulting shoots, will attract the souls of the hungry, who will be able to feed on the crops the Porja have left behind. The common design element, then, is a young shoot, growing from a seed the Porja sowed before they left.
