Please could you provide a breakdown of adult literacy rates in London by borough for each year since 2016?

There is no data for adult literacy post-2016 for London, or elsewhere in England. The most recent data on adult literacy rates in England comes from the Skills for Life Survey, which was last carried out in 2011 and commissioned by the then Department for Business, Innovation and Skills.

Since delegation of the Adult Education Budget to the Mayor of London in 2019/20, we can report the number of learners accessing basic English courses in London, with breakdowns by level and geography. In 2020/21 (full academic year data for London), 25,120 learners enrolled in 32,250 English (literacy) learning courses, and 36,430 learners enrolled in 73,090 ESOL (language) qualifications. AEB data are published on the London Datastore and the most recent release covers delivery from August 2020 to July 2021.
