Denmark supports a high standard of living—its per capita gross national product is among the highest in the world—with well-developed social services. The economy is based primarily on service industries, trade, and manufacturing; only a tiny percentage of the population is engaged in agriculture and fishing. Small enterprises are dominant.
The first of the Nordic countries (Denmark, Finland, Iceland, Norway, and Sweden) to do so, Denmark joined the European Economic Community (EEC; ultimately succeeded by the European Union [EU]) in 1973, at the same time as the United Kingdom, then its most important trading partner. Long-standing economic collaboration between Denmark and the other Nordic countries—including those that have not joined the EU—also continues today. Uniform commercial legislation in the Nordic countries dates to the 19th century.
In the Danish mixed welfare-state economy, private sector expenditures account for more than half of the net national income. Public expenditure is directed primarily toward health and social services, education, economic affairs, foreign affairs, and national defense. The government does not have significant commercial or industrial income.
