US holders of master's degrees in maths earn more than those with degrees in biology or chemistry, finds a report, Higher Education Pays. Research firm College Measures in Rockville, Maryland, analysed first-year salaries for 15,118 master's holders in various fields from 2006 to 2011. Maths graduates typically earned US$49,280–$59,113, whereas biology graduates earned $35,788–$40,561 and chemistry graduates $47,045–$49,421. The numbers, says College Measures president Mark Schneider, imply high demand for mathematical problem-solving skills.
