A new survey by the language learning site Babbel has come to surprising conclusions. "Our data shows that men have a bias towards learning German, Portuguese and Russian, whereas women seem to choose Dutch, French, Italian and Spanish," Thomas Holl, the company's co-founder and president, explained in an email. The survey is based on data provided by Babbel's 1 million customers from around the world - the majority being based in Europe and North America.
