In his 2014 TED Talk, one question that had Hans Rosling’s audience stumped was ‘In all low-income countries across the world today, how many girls finish primary school?’ Most people thought the answer was 20%. The correct answer was 60%. By 2020, this figure had increased to 64%. The share of boys in low-income countries that complete primary school was higher, at 69%. In most countries – even many of the poorest – it’s more likely than not that a girl will finish primary school and get a basic education.iii
