  Pew's landmark India survey found 98% of Indian adults still identify with the religion they were raised in — the lowest switching rate of any large country on Earth.

• United States

  13.4m · 4%

  For every American raised with no religion who has since joined one, about six raised Christian have left — the largest raw switching flow in the Western hemisphere.

  4.3m · 2%

  Catholic share fell from 92% in 1970 to about 57% today, but most of that moved to Evangelical Protestantism rather than out of religion entirely.
