One of a well-established series produced by The Economist, thisguide purportsto explain all you need to know in order to understand and interpret economicfigures. It contains three introductory sections and ten other chapters covering a wide variety of the more commonly quoted economic statistics, from the Big Mac index to the sourcesof economic growth by way of business confidence and the savings ratio. There is a good index and a list of good websites. It iswritten for the non-specialist but intelligent reader, hence the expectation that it should be of use to an A level economist.

Sgnificance: Indicator of output and inflationary pressures

Presented as: Percentage of total capacity

Focus on: Absolute level and trends

Yardstick: 80-90%; more may be inflationary, less indicates room for growth

Released: Monthly, 1-3 monthsin arrears; revised
