Starting with UK-national staff only, Black people constitute just 1.1% of the total of academic professionals. This is the smallest percentage of any ethnic group, although Chinese are close-by with 1.2%. Even when we add together non-national and UK-national staff we find that out of a total academic professional staff of 165445, 2560 are Black, that is, 1.54%, even though they constitute 3.3% of the British population. Alternatively, white academic professionals compose 87.45% of the total and are over-represented in terms of being 86% of the broader population. In contrast, 6.91% of white workers (both UK-national and non-national) are employed as cleaners, catering assistants, security officers, porters and maintenance workers; while 19.27% of Black staff are employed in these roles.
Thus, Black people are significantly under-represented in academic roles and significantly over-represented in manual jobs.
