Demographics
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.
