Ethnic-minority workers are most highly represented in the most senior and junior positions of the UK scientific workforce, says a 7 March report. A Picture of the UK Scientific Workforce, from the Royal Society in London, examines gender, ethnicity and other factors, and is the most comprehensive analysis of its type, says Julia Higgins, chair of the report's steering group. The report finds that black researchers are slightly under-represented in the most senior roles, whereas scientists from China are statistically over-represented in those positions. It also finds that although women comprise just over half of the scientific workforce, they account for less than one-quarter of those in the highest-level positions.
