A research report from the University of Cambridge and RAND Europe shows that investing in languages education in the UK could return more than the investment cost. Researchers explored a gap in the evidence relating to the economic benefits of extending languages education and found that an increase in secondary-school pupils learning one of four different languages could increase UK GDP by billions of pounds over 30 years. In a closely interconnected world, the ability to communicate in different languages has become increasingly important for the globally integrated business community. However, the UK has experienced a sharp drop overall in the number of pupils learning languages since 2004. At a time when the UK government seeks to reset its global economic relationships as part of its vision of 'Global Britain', this research shows that such a decline in languages could have negative effects on the UK's ability to compete internationally.
