  "text": "No smoking gun, but the preponderance of evidence points to smartphones, not economics, as the culprit for the global drop in fertility:\n• In the US and UK, births fell first and fastest in areas that got 4G earliest\n• Birth rates were stable in the US, UK and Australia until 2007; in France and Poland until 2009; in Mexico and Indonesia until 2012; in Ghana, Nigeria and Senegal until 2013-15\n Each of these  inflection points matches local smartphone adoption (see picture).\n• The younger the age group, the sharper the drop.\n• in-person socialising among young adults is dropping. In SK, by 50% in 20 years\n• Sexual dysfunction is higher among heavy social media user\n• Effect is largest in culturally traditional societies — Middle East, Latin America, sub-Saharan Africa\n• Decline holds across countries hit hard by GFC 2008 and those not hit, fast-growing and not growing. \nExcellent again @jburnmurdoch.\nhttps://t.co/RYEMXD2bRM",
