Despite being one of the smallest countries in the world, Singapore is a major force on the economic stage. Singapore is essentially a city-island, well known to be cosmopolitan with a multi-cultural heritage made up of 4 ethnic groups, Chinese, Malays, Indians, Eurasians, all with a strong unified Singaporean identity. Over the years, this multi-cultural environment has been added to by expatriates living and working in Singapore, each bringing their own traditions and culture.
