According to the description, this person is a Dalit.
Explanation:
The Dalits are the lowest caste in India. Even nowadays, they are regarded as impure by the upper castes. Dalits are poor and often have low literacy. They usually work on jobs that involve sanitation, such as disposing of garbage and collecting dead animals from the streets. Such jobs indicate a historical continuity, since the Dalits performed similar tasks in the past. As a matter of fact, that is the reason why they are seen as impure or polluting.
