Jonathan Last, author of What to Expect When No-one’s Expecting, explains how most interventions to increase the fertility rate have failed in countries around the world. While negative incentives seem to work, such as China’s one child policy, encouraging people to have more children seems less successful. As Last explains, a far larger influence on a woman’s decision to have more children than race, education or geography, is how often she attends religious services. (Photo credit: Getty Images)
