The charts below show the split by gender, ethnicity, and disability when we order hourly rates of pay from highest to lowest and group into four equal quartiles. 

Gender

The proportion of women in the upper pay quartile increased slightly over the past year, from 35.7% to 35.9%. However, women are also increasingly represented in the lowest pay quartile, where they now account for 57% of staff, up from 54.1% a year ago.

There was a small increase in the proportion of women in the upper-middle quartile, from 48.2% to 49.5%. In contrast, the proportion of women in the lower-middle quartile decreased from 54.5% to 51.2%.

Ethnicity

Overall representation of BAME staff across the University has remained broadly stable, increasing slightly from 28.8% to 29.4% over the last 12 months. There has been little change in representation across the pay quartiles.

The proportion of staff not disclosing their ethnicity has continued to rise, from 17.5% to 18.4%. Non-disclosure is particularly high in the lowest pay quartile, where ethnicity is unknown or undisclosed for 33.5% of roles. These roles are excluded from ethnicity pay gap calculations, which can only be carried out where ethnicity data is known.

Disability

Across all quartiles, the proportion of staff recorded as having no known disability has decreased compared with last year, while the proportion of staff with a declared disability has changed only slightly. Across the upper quartile, the proportion of staff with no known disability has decreased from 92.5% last year to 78.5% this year, while the proportion with a declared disability changed slightly from 5.3% to 4.6%. In the upper middle quartile, no known disability has fallen from 89% to 71%, with declared disability moving from 6.1% to 4.7%.

In the lower middle quartile, the proportion with no known disability decreased from 86.5% to 53.6%, and declared disability from 7.8% to 5.2%. In the lower quartile, those with no known disability moved from 77.8% to 62.8%, and declared disability from 7% to 4.9%.

The proportion of staff recorded as unknown / prefer not to say increased across all quartiles. In the upper quartile, this category increased from 2.3% to 16.9%, and in the upper middle quartile from 4.9% to 24.3%. In the lower middle quartile, the proportion rose from 5.7% to 41.2%, and in the lower quartile from 15.2% to 32.3%.
