There are slightly more Christians than Muslims in the world today. According to recent Pew Research studies, about 31% of the world population identifies as Christian, with about 24% identifying as Muslim. Coming in third place, about 16% identify as atheist or agnostic. Judaism comes in 9th place with a very small percentage of .2%. All three are Abrahamic religions embracing the same fundamental stories.

I used this research as background for my book “30 Philosophers: A New Look at Timeless Ideas.” For a deeper exploration into the percentages, read–or skim–the article, take the 25-minute deep dive: “Breakdown of Belief Systems.”
