3.6 (answers within ±1.2 count)
Why
About 3.6 per cent. Surveys in European countries routinely find respondents estimating the migrant share of their own country at two or three times the true figure, and the global share is smaller still. The number is not an argument about policy; it is the baseline any such argument has to start from.
