A white paper released by municipal authorities show that Beijing residents are living longer.

According to the Beijing Municipal Commission of Health and Family Planning, the average life expectancy of a city resident is 82 years, while the average in Dongcheng and Xicheng District has reached an impressive 84 years.

The longer life expectancy has caused the city’s elderly demographic to swell in size. Close to one in four Beijing residents are over 60 years of age, totaling just over three million.

While the white paper showed Beijingers are living longer, the news wasn’t all positive. The report also showed that cancer rates continue to increase in the city, and is now the leading cause of death among Beijing residents. 169 of every 100,000 Beijing residents died of cancer in 2014, accounting for 27 percent of all deaths in the city.

The top cancers affecting male Beijing residents are lung, liver, and colorectal cancer, and lung, colorectal, and breast cancer for women.
