major economic and population decline in the late 19th century. The early 20th century saw another period of growth on the back of mining, agriculture and other primary industries, but the world wars had a very negative effect on Hobart, with a severe loss of working age men. Like most of Australia, the post-war years saw an influx of new migrants from Eastern and Southern Europe, such as Italy, Greece, Yugoslavia and Poland. In the later years of the 20th century, migrants increasingly arrived to settle in Hobart from Asia. Despite the rise in migration from parts of the world other than the United Kingdom and Ireland, the population of Hobart remains predominantly ethnically Anglo-Celtic, and has the highest percentage per capita of Australian born residents of all the Australian capital cities. Hobart is a major deep-water port for Southern Ocean shipping, and the last port of call for Australian Antarctic Division and French expeditions to Antarctica. Hobart is also a common port of call for naval vessels from many countries due to the deep harbour of the Derwent River. US Navy vessels often stop for shore leave when returning to the United States from the Middle East. Hobart is a city defined by its geographical position, history and heritage. Classical examples of Georgian, Victorian and Edwardian architecture abound throughout the city, and along with more recently built forms, these buildings define Hobart's character as a city. Hobart has experienced a boom in tourism, and the low cost of living and relaxed way of life have attracted mainland Australians and new migrants to move to the city. Although Hobart has experienced a much slower rate of growth than mainland Australian cities, particularly during the 20th century, Hobart has a stable population, a reasonably strong economy, a clean environment, a healthy sports, arts and culture scene. Etymology The etymology of the name of Hobart comes from the first Lieutenant-Governor of Van Diemen's Land, David Collins, who named the new settlement in honour of the then Secretary of State for War and the Colonies, Robert Hobart, 4th Earl of Buckinghamshire, the Lord Hobart. It was originally referred to as 'Hobart Town', which was often shortened to 'Hobarton', but by 1842 it had grown large enough to officially be recognised as a city, and from 1 January 1881 the 'Town' was formally dropped from its name, leaving the modern name of simply 'Hobart'.
