A landmark study on religion in America has revealed that while people of many faiths seems to be fluid, not locked into one religion, most people of the Hindu faith tend to continue with the same faith for their entire life span.

An article by Andrea Useem, of Religion News Service and published on Beliefnet.com, reports on the U.S. Religious Landscape Survey. Conducted by Pew Forum on Religion & Public Life, the survey results were based on interviews with 35,000 U.S. adults.

This massive survey sheds light on the status of religion in America. It is the first time we've seen this kind of study involving Asian faiths and cultures in America.

"Ninety percent of Hindus marry within their own faith, and eight-in-ten Hindus who were raised Hindu remain so as adults," the article states.

The survey estimated Hindus number about 900,000, or 0.4 percent of all adult Americans.

Vasudha Narayanan, a Hindu scholar at the University of Florida, said that Hindu people stay close to their religion because they are close to their culture. 8 in 10 people of the Hindu faith living in America are foreign born, and tend to stay connected within the community.

Interfaith marriages will change the numbers over time, said Narayanan, as more people marry outside of their faith tradition.

The study also revealed some interesting and somewhat contrasting statistics on Buddhism, as well as covering Christianity, Judaism and Islam.
