But it was this bit that struck me :
Sharon was the most downmarket name, followed by Michelle, Lee, Tracey and Darren. Using GCSE results to show areas where middle-class parental pressure was highest, the research suggested that Felicity, Katherine, Philippa, Penelope and Elisabeth were the poshest first names. “We believe they can be described as the poshest, though you could argue they are the cleverest,” Professor Webber said.
Professor Webber doesn't strike me as a stupid man. As a director of Experian and developer of the MOSAIC system, he probably knows as much about social class and geography as anyone.
So forty years after the privately educated Labour education secretary Anthony Crosland promised to close every grammar school in the country, a man who knows considers educational attainment to be the most useful shorthand for social class in Britain.
