I've learned some important things about the neighbour whose cities, literature, music, art, food and wine I love so much (not to mention the land itself). I had no idea that France's policy of assimilation (contrasted yesterday on Today by Labour MEP, Claude Moraes, with the UK's 'over-arching strategy of integration') means no public or private data on race or religion is published — ram recording here. (Indeed, I think it's correct to say that no census date on race or religion is collected.) As ethnic minorities are effectively not seen, unemployment in areas where they live is four or five times the national average and, on the other hand, word-of-mouth recruitment for jobs means very little social mobility (Claude Moraes).
