By the OECD's thesis, Portugal has a problem coming down the pipeline. According to their figures, the coastal nation's fertility rate has been plummeting for the past generation; only Korea's fertility rate is lower than Portugal's among OECD countries. Though, while that may forecast doom in the future — "sustainable fertility is important to ensure aging populations don't threaten Portugal's welfare systems and future productivity," the organization says — Portugal is doing fine right now. Only 0.05 per cent of Portuguese workers work more than 50 hours a week on average, a low level among OECD countries.
