"The Trusts, a single entity, is the successor to, and sole beneficiary of, seven charitable funds established between 1948 and 1979 by
J. Howard Pew, Mary Ethel Pew,
Joseph N. Pew, Jr., and Mabel Pew Myrin — the adult sons and daughters of
Sun Oil Companyfounder
Joseph N. Pew and his wife, Mary Anderson Pew.
Honoring their parents’ religious conviction that good works should be done quietly, the original Pew Memorial Foundation
[2] was a grantmaking organization that made donations anonymously. The foundation became the Pew Memorial Trust in 1956, based in Philadelphia, the donors’ hometown. Between 1957 and 1979, six other trusts were created, representing the personal and complementary philanthropic interests of the four siblings.
[3][4] The Trusts remains based in
Philadelphia,
Pennsylvania, with an office in
Washington, D.C."
Now Im not saying that means much, but we always need to look at the source of the information, the above captioned related to the Pew Charitable Trust which provides 100% of funding to the Pew Institute who's surveys were relied upon in the OP video.
