The Gender Pay Gap Explained

In the UK, it’s compulsory for all organisations with 250+ employees to publish their Gender Pay Gap (GPG) by calculating the difference between women’s and men’s average hourly earnings. Rather than solely measuring the difference in compensation for men and women with the same role, the calculation must reflect the averages across the entire organisation. So, if more men are in higher-paid roles than women who are also in a lower-salary bracket, the GPG will be wider.  

In 2021 in the UK, the national gender pay gap was 15.4%, continuing the trajectory of a slow decline; in 1997, the national GPG was 27.5%. The UK government publish GPG data, including analysis that shows the experience of different segments of workers, including by age, ethnicity, caring responsibilities, education level, full/part time working status, and region. Extensive research conducted by Professor Correll at Stamford University found that the pay gap between mothers and women without children is more significant than between men and women. 

Across the world, countries record ‘Equal Pay Day’ differently and the dates change annually. The UN General Assembly declared September 18th International Equal Pay Day, estimating that the global average GPG is 20%. In the USA, the date represents how far into the year women must work before they match men’s earnings from the year before. In 2022, the date was March 15th, meaning women work on average 15 months for a man’s 12 months. For women of ethnic minorities, this day differs. In 2022 Black women’s Equal Pay Day was September 21st, and the date for Latina women was December 8th, according to Equal Pay Today. 

In the UK, Equal Pay Day is when women start working for no pay for the work that they will do that year. In 2021 it was November 18th on average, correlating to the 15.4% average GPG, but the date was significantly earlier for women of ethnic minorities. For Black Caribbean women the date was 26th October, for Black African women the date was 27th September and for Bangladeshi women the date was 19th September. ThePakistani women experience the most significant GPG, with their Equal Pay Day as the 8th September – representative of a 31% GPG.
