Hans Rosling se zapitao: Da li neke religije imaju višu stopu reprodukcije nego druge -- i kako to utiče na globalni rast populacije?  Govoreći na TEDxSummit u Dohi u Kataru, prikazao je podatke u grafikonima kroz vrijeme, poredeći religije. Sa njegovim prepoznatljivim humorom i oštroumnošću, Hans dolazi do iznenađujućeg zaključka o stopama fertilnosti u svijetu. 

Hans Rosling: Religije i bebe

Fertility rates around the world have dropped sharply, reaching an average of about two children per woman, regardless of the dominant religion. Even countries with widely different incomes and faiths, like Bangladesh and Qatar, now share similar birth rates. This global change is driven by factors such as child survival, education for women, and access to family planning. Despite common beliefs, religion plays a minor role compared to these social and economic forces.
