The UK, a leading trading power and financial center, is one of the quintet of trillion dollar economies of Western Europe. Over the past two decades, the government has greatly reduced public ownership and contained the growth of social welfare programs. Agriculture is intensive, highly mechanised, and efficient by European standards, producing about 60% of food needs with less than 2% of the labor force. The UK has large coal, natural gas, and oil resources, but its oil and natural gas reserves are declining and the UK became a net importer of energy in 2005; energy industries now contribute about 4% to GDP. Services, particularly banking, insurance, and business services, account by far for the largest proportion of GDP while industry continues to decline in importance. (CIA World Factbook)
