In 2010, Bahrain's population grew to 1.2 million, of which 568,399 were Bahraini and 666,172 were non-nationals. It had risen from 1.05 million (517,368 non-nationals) in 2007, the year when Bahrain's population crossed the one million mark. Though a majority of the population is Middle Eastern, a sizeable number of people from South Asia live in the country. In 2008, approximately 290,000 Indian nationals lived in Bahrain, making them the single largest expatriate community in the country, the majority of which hail from the south Indian state of Kerala. Bahrain is the fourth most densely populated sovereign state in the world with a population density of 1,646 people per km2 in 2010. The only sovereign states with larger population densities are city states. Much of this population is concentrated in the north of the country with the Southern Governorate being the least densely populated part. The north of the country is so urbanised that it is considered by some to be one large metropolitan area.
