The information requested falls within the responsibility of the National Statistician, who has been asked to reply.
Letter from Jil Matheson, dated 31 March 2008:
The National Statistician has been asked to reply to your recent Parliamentary Question asking what the decile boundary earnings were for (a) London and (b) each London borough in the latest 12 month period for which figures are available, broken down by age cohort. I am replying in her absence. (196517)
Levels of earnings including medians, deciles and quartiles, are estimated from the Annual Survey of Hours and Earnings (ASHE), and are provided for employees on adult rates of pay, whose pay for the survey period was not affected by absence. The ASHE, carried out in April each year, is the most comprehensive source of earnings information in the United Kingdom.
I attach a table showing the mean, deciles and quartiles for gross weekly earnings for full time employees in London by age for 2007. Figures for each London borough broken down by age group are not available. However, aggregate results for London boroughs can be obtained on the National Statistics website at:
