This article is an addendum to WGBH News special series, "Caste in America." Read parts one, two, three and four. This series was produced in partnership with the Pulitzer Center.

In WGBH’s exploration of “Caste in America,” we interviewed more than 30 people about their experiences and views of this hierarchical system. We wanted to know how caste affected them personally, their analyses of this ancient division and its impact on their lives in the United States. We spoke with Indians who did not know to what caste they belong. We interviewed others who identified as Brahmin, Kshatriya, Sudra, Vaishya and Dalit. Dalits, an outcaste group, are a minority among the nearly 3 million Indians in the U.S. and Canada. But even in the diaspora — away from the harsh realities that define everyday life for those formerly described as “untouchables” — the inherent bigotry of caste has followed. Other Indians have had entirely different experiences with caste. Several people we spoke with said they have never thought about or felt its effects. Here are a few of the voices of people we interviewed for our series.

Rakesh Pandey — Boston: Pandey is a lecturer on operations and technology management at Boston University’s Questrom School of Business. He arrived in the U.S. more than three decades ago. He is a Brahmin who supports “reservations” (affirmative action) for Indians in India and is considering the impact of reservations on professional Indian migration to the U.S.
