Agriculture remains a major part of the Spanish economy and employs, along with forestry and fishing, 7 percent of the labour force.
The two main agricultural products are grapes, used to make wine, and olives, used to make olive oil. Other main products include oranges, almonds, cereal grains (especially barley, wheat, and rice), vegetables (especially tomatoes and onions) and root crops (mainly potatoes and sugar beets).
The raising of livestock, especially sheep and goats, is an important industry. In 2002 livestock on farms included 24.3 million sheep, 23.9 million pigs, 6.4 million cattle, and 248,000 horses.
The cork-oak tree is the principal forest resource of Spain, and the annual production of cork, more than 52,000 metric tons in the late 1980s, placed Spain among the world leaders. The yield of Spain’s forests is insufficient for the country’s wood-pulp and timber needs.
The fishing industry is important to the Spanish economy. The catch consists mostly of sardines, mussels, tuna, hake, and squid.
The mineral wealth of Spain is considerable consisting mainly of coal, iron ore, zinc, copper and lead. Gold and silver are also mined and petroleum is extracted. The main coal mines are in the northwest, near Oviedo; iron-ore deposits are in the same area, around Santander and Bilbao whilst copper and lead are mined in Andalusia.
The main manufactured goods in Spain are textiles, iron and steel, motor vehicles, chemicals, clothing, footwear, ships and boats, refined petroleum, and cement. Spain is one of the world’s leading wine producers. About 31 percent of the labour force is employed in manufacturing, mining, and construction.
Over 50 % of Spain's electricity comes from conventional thermal plants fuelled by coal or refined petroleum. Hydroelectric power accounts for around 18 percent, and nuclear installations about 27 percent.
Spain is a full member of the European Single Currency. On January 1, 2002, the Euro came into circulation and within a few months the former currency, the peseta, ceased to be legal tender.
Spain is served by a large number of national and international commercial banks. The main stock exchanges are in Madrid, Barcelona, Bilbao, and Valencia.
Spain's main imports include machinery, mineral fuels, transportation equipment, food products, metals and metal products, and textiles. Her exports include motor vehicles, machinery, basic metals, vegetable products, chemicals, mineral products, and textiles. France, Germany, Italy, the United Kingdom, Portugal, and the United States are the chief export markets whilst France, Germany, Italy, the United Kingdom, Belgium, the United States, and Japan provide most of the imports. A balance of trade deficit is the norm.
Spain is the world's third most visited country after the USA and France. Revenue from the 78 million tourists who visited Spain in 2002 helped make up for Spain’s considerable trade deficit.
