Which religious groups are oldest, youngest?

from PRC:

"The U.S. religious landscape is already in the midst of some dramatic changes when it comes to the growth or decline of people with certain religious identities. And while it is impossible to predict exactly how that landscape will shift in the future, some key demographic factors — particularly age — can provide a clue as to how things might unfold in the coming decades.

"For example, religious groups whose members are younger may be more likely to grow, not only because those members will live longer, but also because more of them are still of childbearing age ...

"Members of some non-Christian faiths also are very young – U.S. Muslims and Hindus in the survey each have a median age of 33. About four-in-ten Muslim adults in the U.S. are under the age of 30, and nine-in-ten Hindu adults are under 50.

"At the other end of the spectrum, members of two Presbyterian denominations are among the oldest of the 30 religious groups we were able to analyze, which include Protestant denominations...."

The new age religion would be the oldest post flood.   It started with Nimrod and Semiramis shortly after the flood.
