TABLE 19. SPECIALISATION AND COVERAGE RATIOS BY INDUSTRY

The first column in this table shows the specialisation ratios for an industry. An industry may produce a number of products, some of which may be primary to that industry and some of which may be primary to other industries. The specialisation ratio shows the proportion of an industry's output that is primary to that industry.

For example, 93.6% of output of the Sheep, grains, beef and dairy cattle industry is attributed to the output primary to this industry, 94.2% of the output of the Other agriculture industry is attributed to the output primary to this industry and so on.

The second column in this table shows the coverage ratios for a product. A product may be supplied by more than one industry. The coverage ratio shows what proportion of the total domestic supply of a product is produced by the industry to which the product is primary.

For example, the entire Sheep, grains, beef and dairy cattle product is produced by the Sheep, grains, beef and dairy cattle industry to which the product is primary, 93.9% of Agriculture, forestry and fishing support services is produced by the Agriculture, forestry and fishing support services industry to which the product is primary and so on.
