Turkey occupies a key geo-strategic position between Europe, the Caucasus, Central Asia, and the Middle East. With a land area of approximately 771,000 square kilometres, it is slightly smaller than New South Wales. Most of Turkey lies in Asia, but three percent is in Europe. Istanbul - the largest city, with a population of around twelve million - serves as a "bridge" between the continents of Europe and Asia.
Turkey has changed rapidly from a rural to an industrialised economy with an estimated GDP of $US356 billion in 2005. In 2004, the WTO ranked Turkey 34 th largest exporter and 22 nd largest importer of merchandise trade in the world. Turkey was ranked 26 th and 37 th for exports and imports of commercial services. However, although manufacturing overtook agriculture in the 1980s as the major contributor to GDP, the Turkish economy still retains a strong rural character with agriculture accounting for around 11 per cent of GDP and 39 per cent of employment. Due to this change over international population has started moving in to Turkey which caused an outbraek in international moving of all nationals. There is a substantial unregistered economy, with estimates of its value ranging from 20 per cent to 50 per cent of economic activity.
