Venezuela was one of three countries that emerged from the collapse of Gran Colombia in 1830 (the others being Ecuador and New Granada, which became Colombia). Venezuela is considered to be among the world's 17 most biodiverse countries. Venezuela remains highly dependent on oil revenues, which account for roughly 90% of export earnings, more than 50% of the federal budget revenues, and around 30% of GDP. Tax collection, Venezuela's primary source of non-oil revenue - is expected to surpass $23 billion in 2006, exceeding the yearend collection goal by more than 20%. Fueled by higher oil prices, record government spending helped to boost GDP growth in 2004 and 2005 to approximately 18% and 11%, respectively. Economic growth in 2006 reached about 9%. This spending, combined with recent minimum wage hikes and improved access to domestic credit, has fueled a consumption boom, car sales in 2006 increased by around 70%, but has come at the cost of higher inflation. Despite government attempts to withdraw liquidity from the economy, Venezuela's money supply set a record in June 2006, approximately 70% higher than the previous year. Imports have also jumped significantly.
