UK Economy Tracker #9 – 2022 Q2

August 22, 2022 By Nigel Marriott

UK Inflation has risen sharply since the start of 2022 and dominates the media and politics today.  It is now having knock on effects, most notably on wage rises which are lagging behind inflation.  The aftermath of the COVID19 induced recession continues to be considerable economic uncertainty.

Pay Gaps #27 – Don’t mention the Disability Pay Gap!

June 11, 2022 By Nigel Marriott

“I mentioned it once but I think I got away with it!”

Basil Fawlty didn’t get away with it in Torquay and neither did this manager.

HR Manager – “Our disability pay gap is zero which surprises me”

Me – “How many disabled employees do you have?”

My response sums up my view on Disability Pay Gap Reporting (DPGR).  The manager commented on their pay gap whilst I queried their employment gap.  As a statistician who happens to be disabled, I consider the conventional disability pay gap statistic to be at best irrelevant and at worse a lie.

UK Economy Tracker #8 – 2022 Q1

May 31, 2022 By Nigel Marriott

Whilst COVID19 was ravaging the world in 2020 & 2021, I felt there was little point in updating my quarterly UK Economy Tracker.  Now the pandemic over in the UK, it’s time to see how much damage the pandemic did to the economy.  Going forward, the future is very uncertain but I hope by placing the latest data in the context of the past, I can discern what pointers I should keep an eye on.

Pay Gaps #26 – Why are female dominated public sector gender pay gaps so large?

May 26, 2022 By Nigel Marriott

… & why are gender pay gaps so small at male dominated private sector employers?

When I asked people recently who on average had the larger gender pay gap, the results were –

  • 62% said female dominated (>80% employees are women) public sector (snapshot date 31st March) employers. There were 420 such employers in April 2021 who reported their UK gender pay gap.
  • 38% said male dominated (>80% employees are men) private sector (snapshot date 5th April) employers. There were 1584 such employers in April 2021 who reported their UK gender pay gap.

The majority are correct. In April 2021, for every £1 paid to the average man, the average woman was paid 90p at the average male dominated private sector employer and 77p at the average female dominated public sector employer. For context, the average woman at the average employer in the finance sector (who are often in the news for having large pay gaps) is paid 75p.

Pay Gap Trends #5 – Has pay gap reporting narrowed the gender pay gap?

May 13, 2022 By Nigel Marriott

Disinterested employers were 20% less likely than engaged employers to have narrowed their UK gender pay gap between 2017 & 2021 .  I draw this conclusion from a statistical model using ~6,000 employers which removed the effect of confounders such as size, sector, furlough, gender ratio, etc.  Once accounted for, I found 61% of those reporting their pay gap for 2019 had narrowed their pay gap by 2021 compared to 55% of those not reporting 2019 data.

UK Weather Tracker #63 – April 2022

May 2, 2022 By Nigel Marriott

My mother got me excited today when she said she had read it was the driest April since 1842 but she was mistaken unfortunately.  It was drier than usual and given March was also dry, the UK is on track for a dry Spring.  Otherwise April 2022 was completely unremarkable.
