The Economist's lifestyle and culture magazine spin-off Intelligent Life is increasing in frequency from quarterly to six times a year.

It launched in 2007 and now claims a global print circulation of 175,000 (Intelligent Life is not ABC audited).

Publisher Des McSweeney said: "We pride ourselves on our long-form journalism and by going bi-monthly, we can take this approach further with even more topical material as well as our in-depth features, memoirs and photo essays."
