Nearly a quarter of Beijing's registered residents were 60 years old or more at the end of 2014, according to data revealed by the capital's office for senior citizens on Thursday.
The number of over-60s in Beijing rose by 174,000 from a year earlier to 2.967 million at the end of 2014, accounting for 22.3 percent of the registered population, said the office. Over-70s accounted for nearly half the total elderly population in the city.
The number of over-80s rose from 2013 to 2014 by 42,000, a year-on-year increase of 8.8 percent. Beijing had 643 registered centenarians, 203 males and 440 females, at the end of 2014, growing by 54 from 2013, according to the office.
China's population is aging rapidly, with 202 million people, or nearly 15 percent of the total population, at or above the age of 60 by the end of 2013, according to the Ministry of Civil Affairs. It expects the number to exceed 300 million by 2025.
