Number of students that have learnt with micro:bit

At the end of February 2023 our estimate was that 39 million students have learnt with micro:bit. This includes use of the BBC micro:bit board and other micro:bit resources.

It is a global estimate of how many students have been reached since the BBC micro:bit board was first distributed in 2016. The estimate is based on extrapolation from worldwide sales, donations and website data using a multiplier that has been calculated based on detailed, independent research into usage within the UK and how this is reflected in UK sales, donations and website usage data. Fresh data is collected regularly to optimise the accuracy of this estimate.
