Hong Kong is one of two Special Administrative Regions (SARs) of the People's Republic of China (PRC), the other being Macau. It is a place with multiple personalities, as a result of being both Cantonese Chinese and under a more recent contemporary ex-British influence. Today, the former British colony is a major tourism destination for China's increasingly affluent mainland population. It is also an important hub in East Asia with global connections to many of the world's cities. It is a unique destination that has absorbed people and cultural influences from places as diverse as Vietnam and Vancouver and proudly proclaims itself to be Asia's World City.
As one of the world's leading international financial centres, Hong Kong has a major capitalist service economy characterised by low taxation and free trade, and the currency, Hong Kong dollar, is the eighth most traded currency in the world. The lack of space caused demand for denser constructions, which developed the city to a centre for modern architecture and the world's most vertical city. Hong Kong has one of the highest per capita income in the world. The dense space also led to a highly developed transportation network with public transport travelling rate exceeding 90 percent, the highest in the world. Hong Kong has numerous high international rankings in various aspects. For instance, its economic freedom, financial and economic competitiveness, quality of life, corruption perception, Human Development Index, etc., are all ranked highly.
