Pay Gap Trends #3 – Did the UK gender pay gap narrow in 2019?

June 14, 2020 By Nigel Marriott

On 24th March 2020, the UK government suspended enforcement of the gender pay gap reporting deadline of 5th April.  As of today, just over 50% of employers have reported their 2019 gender pay gap figures.  Despite this shortfall, I have used statistical imputation methods to calculate that the median gender pay gap narrowed in 2019 from 9.6 pence in the pound to 9.0-9.2 pence in the pound.

September 12, 2019 By Nigel Marriott

The 2019 summer was the 7th wettest on record but was also unusually warm given the amount of rain that fell.  I have made a prediction that summer 2020 will not be a good one!

Pay Gap Case Study #2 – Year on year trends, the good, bad and Unilever

April 24, 2019 By Nigel Marriott

Welcome to my next case study where I look at the pay gap figures of Unilever Ltd.  Unilever turn out to be a very interesting case study for analysing year on year changes in their published statistics.  In this case I will be looking at the changes between 2017 and 2018 for the two Unilever business units that have submitted GPG data which are:-

  1. Unilever UK Ltd
  2. Unilever UK Central Resources Ltd

Clicking on those links will take you to the government’s gender pay gap website where you can see their published figures.  For this post, I will be using my own spreadsheet which you can download for yourselves here.
