The latest government data, published in November 2023, reveals that the median average UK weekly wage for full time workers (in England and Wales) is £682 gross (that's the equivalent to an annual pre-tax salary of just over £38,000) – an increase of 6.2% compared to 2022.
Median is the salary where there are as many earning more as earning less. It is a way of avoiding results skewed by a small number of extreme earnings ( or lack of).
Mode and mean are other measures of averaging a range of variables.
