Ye of no faith: From 3.5 to 4.6 percent the last decade

While the percentage of Mexicans who define themselves as catholic has dropped from 88 to 83.9 percent the past decade, according to the Mexican census, many of these have simply switched religions, in particular to Pentecostalism. Notably in states such as Chiapas, Campeche, and Tabasco, the percentage of catholics is as low as 59.5-64.1-65.6 percent respectively.

Yet also one sign of human progress: Those who deny living by magic writings handed down from heaven on high during the Bronze age, or of any kind, rose from  3.5 to 4.6 percent .
