"The total value added of the copyright-based industries in Colombia reached Col$9.5 millions of millions in 2005 (approximately 4,800 million US dollars) from Col$5.7 millions of millions in 2000. As a percentage of GDP, the CBI represented an average of 3.3 per cent throughout the period. In real terms, i.e. discounting price increases, the value added of the CBI grew 29 per cent in five years from Col$2.4 millions of millions in 2000 to Col$3.1 millions of millions in 2005 (at 1994 constant prices). During the period analyzed, the CBI had an average participation in GDP of 3.3 per cent. This rate is similar to the share of electricity and gas, slightly higher than the contribution of crude oil and natural gas extraction and more than double that of coffee and coal. The latter comparison emphasizes the importance of the CBI in national output since coffee and coal are two important Colombian exports, which have a significant share in the global market. The composition of the CBI is as follows: the core industries represent 56 per cent of the total value added generated by these economic activities, followed by interdependent (24 per cent), non-dedicated support (13 per cent) and partial copyright industries (8 per cent)."
