The transcript below is from “Through the Wormhole� S05E01 and concerns analysis of religious census data from around the world. The whole episode focuses on God, but the part referred to below starts at around the 19 minute mark.
Danny Abrams* is an applied mathematician at Northwestern University. Religious affiliation has been tracked via census reports in many countries for up to 250 years in some cases and we can see how the sizes of religious groups have grown and shrunk. We looked at 85 regions around the world and in every case, every place where it’s ever been measured, the fastest growing religious minority is the non-affiliated, the group of people who don’t affiliate with any religion at all. To find out if this trend will continue, Danny plugged census data from nine different countries (Australia, Canada, Finland, Ireland, Switzerland, Czech Republic, Austria, Netherlands, New Zealand) into his mathematical models and made a surprising prediction. Religion is heading towards a tipping point. According to Danny, by the year 2050, in 6 out of the 9 countries he studied, religiously affiliated people will be a minority. The wheels of society are making people align. A non-religious majority looks set to emerge.
