Shanghai has a life expectancy of 83.18 years for the city's registered population, the highest life expectancy of all cities in mainland China. This has also caused the city to experience population aging—in 2021, 17.4% (4.3 million) of the city's registered population was aged 65 or above. In 2017, the Chinese government implemented population controls for Shanghai, resulting in a population decline of 10,000 people by the end of the year.
