Residents of sub-Saharan African countries were the most likely to want to move abroad permanently, the polls conducted in 135 countries between 2007 and this year by Gallup showed. On average, 38 percent of the adult population in sub-Saharan Africa, or around 165 million people, said they would up stakes and head for another country if they had the chance. The most popular destination was the United States, where nearly a quarter of the 700 million -- around 165 million people -- said they would like to settle. In joint second were Britain, Canada and France, each being named as the preferred destination of around 45 million people.
