as the American Institute, the British School, the French Academy, the Scandinavian Institutes, and the German Archaeological Institute. There are also specialised agencies of the United Nations, such as the Food and Agriculture Organization (FAO). Rome also hosts major international and worldwide political and cultural organisations, such as the International Fund for Agricultural Development (IFAD), World Food Programme (WFP), the NATO Defence College, and the International Centre for the Study of the Preservation and Restoration of Cultural Property (ICCROM). According to the GaWC study of world cities, Rome is a "Beta +" city. The city was ranked in 2014 as 32nd in the Global Cities Index, the highest in Italy. With a 2005 GDP of €94.376 billion (US$121.5 billion), the city produces 6.7% of the national GDP (more than any other single city in Italy), and its unemployment rate, lowered from 11.1% to 6.5% between 2001 and 2005, is now one of the lowest rates of all the European Union capital cities. Rome's economy grows at around 4.4% annually and continues to grow at a higher rate in comparison to any other city in the rest of the country. This means that were Rome a country, it would be the world's 52nd richest country by GDP, near to the size to that of Egypt. Rome also had a 2003 GDP per capita of €29,153 (US$37,412), which was second in Italy (after Milan), and is more than 134.1% of the EU average GDP per capita. Rome, on the whole, has the highest total earnings in Italy, reaching €47,076,890,463 in 2008, yet, in terms of average workers' incomes, the city places itself 9th in Italy, with €24,509. On a global level, Rome's workers receive the 30th highest wages in 2009, coming three places higher than in 2008, in which the city ranked 33rd. The Rome area had a GDP amounting to $167.8 billion, and $38,765 per capita. Although the economy of Rome is characterised by the absence of heavy industry, and it is largely dominated by services, high-technology companies (IT, aerospace, defence, telecommunications), research, construction and commercial activities (especially banking), and the huge development of tourism are very dynamic and extremely important to its economy. Rome's international airport, Fiumicino, is the largest in Italy, and the city hosts the head offices of the vast majority of the major Italian companies, as well as the headquarters of three of the world's 100 largest
