Wars, inter-state conflicts and climate breakdown result in the mass movement of peoples. According to the World Economic Forum, wars, violence or persecution forced 11 million people to flee their homes throughout 2019, mostly from low or middle-income countries, nearly double the figure for 2010 and creating a global population of almost 80 million displaced. The United Nations High Commissioner for Refugees reported that more than one per cent of humanity, that is one out of every 96 people in the world, was displaced in 2020, with more and more unable to return home.
