There are enough former Catholics in the United States to make up a large Christian denomination of their own.

According to the Religious Landscape Survey conducted by the Pew Forum on Religion and Public Life in 2008, one in 10 American adults identifies as an ex-Catholic. And of the 25 percent of American adults who are still Catholic, only one in four attend mass regularly.
