However, analysts at Citigroup said the increase in jobs continued to be concentrated in sectors with low pay, which dragged down overall wage growth. "We estimate that the number of employees rose 3.9pc year-on-year between May and July in sectors where the typical level of pay is at least 20pc below the average for all sectors: conversely, employment fell slightly (0.1pc y-o-y) in sectors with pay levels that are at least 20pc above the UK average," said Michael Saunders, chief UK economist at Citi.
