May 4, 2026 By Nigel Marriott

The government requires nearly all employers with a headcount of 250 or more on their snapshot date to submit gender pay gap data.  All data is available to the public and can be found on the government’s gender pay gap website.  I have downloaded this to create a more user friendly and visually informative spreadsheet for you to download and use.

All data shown here is up to date as of 3rd May 2026.  The next update is planned for July 2026.

Stats Training Materials – Sampling & Surveys

January 17, 2025 By Nigel Marriott

The core expertise that Statisticians offer to the world is drawing conclusions from small samples.  Therefore, knowing how to design surveys, estimate the right sample size, decide on the right way to ask the question or measure a property are all essential skills for any statistical thinker.  The skills you need to be competent in Sampling & Surveys are best captured by my Survey Wheel.

Pay Gap Trends #4 – Did the UK gender pay gap narrow in 2020?

September 5, 2021 By Nigel Marriott

This article was last updated using data submitted as of 4th September 2021.

In February 2021, the EHRC confirmed that all employers with a headcount of 250 employees or more would have to submit their gender pay gaps based on the 2020 snapshot date.  Due to the lateness of this confirmation, they also stated that no enforcement action would be taken prior to the end of September 2021.  As result, fewer employers than expected have reported 2020 data so far so I have used two methods of imputation to estimate that the median gender pay gap among these employers narrowed by 0.2 to 0.3 pence in the pound in 2020.

Pay Gaps #22 – My 7 + 5 recommendations for amending UK pay gap legislation

June 30, 2021 By Nigel Marriott

When gender pay gap reporting was introduced by the government for the 2017 snapshot date for all employers with a headcount of 250 or more, it was made clear they would evaluate how the legislation had worked after 5 years.  We are now in the 5th year of pay gap reporting and I would like to submit to the government 7 recommendations to improve the way employers’ data is reported and 5 recommendations to improve the data used in the calculations and to reduce various distortions.

Pay Gaps #21 – No employer has a gender & ethnicity pay gap! Let’s celebrate!

April 19, 2021 By Nigel Marriott

It’s April 2029 and the government is trumpeting the fact that no employer in the UK has a gender pay gap or ethnicity pay gap.  All employers say that their median woman’s hourly pay is the same as the median man’s hourly pay and their median white employee’s hourly pay is the same as their median non-white employee’s hourly pay.  Would you be joining in the celebrations?
