Beijing's population decline was in line with national trends, with China's population falling last year for the first time in six decades, weighed down by rising living costs especially in big, sprawling cities like Beijing, weak economic growth, and changing attitudes towards raising a family.
"These figures are expected, especially for Beijing," said Xiujian Peng, senior research fellow at the Centre of Policy Studies at Victoria University in Australia.
The birth rates in Beijing and other cities and provinces are calculated based on the permanent residents not including migrant population, she said.
Beijing's natural population growth was minus 0.05 per 1,000 people last year.
China's birth rate last year was 6.77 births per 1,000 people, the lowest on record, while the country's death rate, the highest since 1974, was 7.37 deaths per 1,000 people.
