According to a data analysis released on Thursday by UNICEF, the U.N. children's agency, almost two-thirds of the world's children under age 1 — nearly 90 million — live in countries where dads are not entitled by law to take paid paternity leave. In these countries, this policy is typically decided by employers. For Jody Heymann, founding director of World Policy Analysis Center, the data draws attention to a glaring gap in expectations on gender roles. "To achieve gender equality both in the workplace and the home, it's essential for men to have an equal chance to be there with their newborn babies," she says.
