An estimated 2 to 5 million Mexicans (~2% to ~4.5%) adhere to the veneration of Santa Muerte, and most of them see themselves as members of the Catholic Church, even though the Vatican condemns this practice. Movements of return and revival of the indigenous Mesoamerican religions (Mexicayotl, Toltecayotl) have also appeared in recent decades.Buddhism and Islam have both made limited inroads, through immigration and conversion.
