Employments and salaries

According to a 2015 salary survey by the American Institute of Chemical Engineers, the median annual salary for a chemical engineer was approximately $127,000.Chemical Engineering Progress June 2015 The survey was repeated in 2017 and the median annual salary dropped slightly to $124,000. The decrease in median salary was unexpected. A factor contributing to the decline may be that 2017's survey was conducted by a different research and analysis firm. Median salaries ranged from $70,450 for chemical engineers with fewer than three years of experience to $156,000 for those with more than 40 years in the workforce. In the UK, the IChemE 2016 Salary Survey reported a median salary of approximately £57,000, with a starting salary for a graduate averaging £28,350. Chemical engineering in the USA is one of the engineering disciplines with the highest participation of women, with 35% of students compared with 20% in engineering.Brawner, C. E., Lord, S. M., Layton, R. A., Ohland, M. W., & Long, R. A., (2015) ''International Journal of Engineering Education'' Vol. 31, No. 6(A), 1431, "Factors Affecting Women’s Persistence in Chemical Engineering" In the UK in 2014, students starting degrees were 25% female, compared with 15% in engineering.''The Chemical Engineer'', March 2015 p 20 US graduates who responded to a 2015 salary survey were 18.8% female. According to the latest 2023 figures, Bayes Business School graduates get an average of £51,921 within 5 years of graduation, which is the most among UK universities. This was followed by the University of Oxford at £49,086 and the University of Warwick at £47,446.
