In 2017, the number of Beijing's permanent residents was 21.707 million, 22,000 fewer than in 2016, according to the Standing Committee of Beijing Municipal People's Congress.

 

According to a report reviewed by the committee, the number of permanent residents in the city's six urban districts continues to decrease. In 2016 and 2017, Beijing saw a total decline of 740,000 permanent residents in the six districts, down 3 percent year-on-year.

 

Beijing plans to cap its population as it seeks to address "big city diseases" such as traffic congestion and pollution.
