INDUSTRY RATIOS
A range of performance measures, expressed as ratios or percentages, can be produced from the data available from businesses' financial statements. These measures are presented in table 2.2 for each industry. Definitions are provided in the Glossary. Information about the uses and limitations of these measures can be found in Explanatory Notes paragraphs 27-31.
Most industries have reported relatively stable profit margins over time. The main exceptions to this, which each recorded large decreases in their profit margins between 2007-08 and 2008-09, were Rental, hiring and real estate services (from 44.0% to 16.3%), Education and training (private) (from 24.5% to 9.8%) and Information, media and telecommunications (from 15.7% to 9.1%). Mining returned the largest profit margin (37.1%), however this margin has been steady over time.
The IVA per person employed was substantially higher in Mining ($790,900) than in the next highest industry, Electricity, gas, water and waste services ($273,100).
