The territory's population is 7.03 million. In 2009, Hong Kong had a birth rate of 11.7 per 1,000 population and a fertility rate of 1,032 children per 1,000 women. Residents from mainland China do not have the right of abode in Hong Kong, nor are they allowed to enter the territory freely. However, the influx of immigrants from mainland China, approximating 45,000 per year, is a significant contributor to its population growth – a daily quota of 150 Mainland Chinese with family ties in Hong Kong are granted a "one way permit". Life expectancy in Hong Kong is 79.16 years for males and 84.79 years for females as of 2009, making it one of the highest life expectancies in the world.
About 95% of the people of Hong Kong are of Chinese descent, the majority of whom are Taishanese, Chiu Chow, other Cantonese people, and Hakka. Hong Kong's Han majority originate mainly from the Guangzhou and Taishan regions in Guangdong province. The remaining 5% of the population is composed of non-ethnic Chinese. There is a South Asian population of Indians, Pakistanis and Nepalese; some Vietnamese refugees have become permanent residents of Hong Kong. There are also Europeans (mostly British), Americans, Canadians, Japanese, and Koreans working in the city's commercial and financial sector. In 2008, there were an estimate of 252,500 foreign domestic helpers from Indonesia and the Philippines working in Hong Kong.
Hong Kong's de facto official language is Cantonese, a Chinese language originating from Guangdong province to the north of Hong Kong. English is also an official language, and according to a 1996 by-census is spoken by 3.1 percent of the population as an everyday language and by 34.9 percent of the population as a second language. Signs displaying both Chinese and English are common throughout the territory. Since the 1997 handover, an increase in immigrants from mainland China and greater integration with the mainland economy have brought an increasing number of Mandarin speakers to Hong Kong.
