Pay Gap#5 – Calculate your gender pay gap with my free calculator!

by

If you are responsible for uploading your gender pay gap figures to the government’s portal, you may want to be sure that your figures are correct.  I have analysed the 2017 data and I have identified that between 10-20% of organisations have submitted incorrect data.  In most cases, this is because the existing government guidance for your calculations is poorly written and is open to misinterpretation.

Until the government rewrites its guidance to make it easier to understand, why not download my free spreadsheet which will do all the calculations for you?

Pay Gap#4 – 12 ways to improve public confidence in gender pay gap data

by

This is intended to be a briefing note for anyone interested in seeing gender pay gap data being used properly.  Gender pay gap data is now part is the business and political discourse in the UK and is likely to be so for some time.  If the goal of gender pay gap reporting is to remove disparities in pay between men and women, then it is essential that the public has confidence in both the quality of the data being published and the correctness of any interpretations of the results.  With the first round of data reporting out of the way, it is time to learn lessons, identify improvements and see that these are implemented.  Following extensive analysis of the 2017 round of results, I have identified 12 ways to improve the quality of the data being reported and make interpretations of the results more meaningful.

Pay Gap#3 – Life on Mars

by

The UK is facing the challenge of interpreting the first round of gender pay gap data and I listed some of the challenges in my article “the 7 ways to misuse gender pay gap data“.  In statement 4 of that post, I stated that a lack of understanding of the laws of chance will result in unjustified allegations of gender discrimination against some organisations and so in this article, I want to demonstrate the laws of chance using nothing more than some dice and coins, a process known as simulation.  My simulation model is simple enough for you to repeat by yourselves and at the end, you will have a better idea of the extent to which median gender pay gaps can vary even when organisations do not discriminate in any shape or form.

Pay Gap#2 – 1 in 10 organisations have published incorrect gender pay gap data. Are you one of them?

by

The first round of gender pay gap data is now available for all organisations employing more than 250 employees.  The UK now faces the challenge of interpreting this data and using it properly which will not be easy given “the 7 ways to misuse gender pay gap data” I recently wrote about.  In the short term, there is an immediate need to resolve errors in the data published and I will demonstrate that potentially 10-15% of organisations have entered incorrect data into the government’s database.

Pay Gap#1 – 7 ways to misuse gender pay gap data

by

April 2018 was the deadline for submitting gender pay gap results and we now have the first detailed picture of how pay differs between men and women in the UK.  A nifty government website can be used to look up pay gap details for any company employing more than 250 employees and you can also download the results for further analysis.  So what will happen next?  Will the data be used properly to inform debate about how men and women are paid or will it be misused for personal and political gain?

I believe this data can be of benefit to the debate around gender equality but my fear is that to begin with, it will be misused, misinterpreted and reinforce the saying “lies, damned lies and statistics”.  So if you want to misuse gender pay gap data, who better to ask that a professional statistician like me who will show you how you can do this by commenting on 7 plausible statements.

Pay Gap#0 – Where can I find gender pay gap data?

by

The government requires all organisations employing 250 or more employees to submit gender pay gap data.  The first set of submissions were completed in April 2018 but these figures refer to pay made in April 2017 i.e. a year ago.  Organisations can submit their 2018 data now if they wish and not wait for the deadline of April 2019.  All data is available to the public and can be found on the government’s gender pay gap website.  I have downloaded this data and created a spreadsheet tool to present the data in a more user-friendly and visual format.
