The Hunan People’s Congress warned that most cities in the province had failed to urgently address their declining birth rates, with a survey finding that only four out of 14 had rolled out detailed plans to boost births by the end of April – against a previous deadline of end-2022.
Despite a slew of pronatalist incentives and slogans being rolled out across the country to encourage births, demographic experts have conceded that immediate effects are unlikely, suggesting China should accept and adapt to the new norm.
According to the Hunan report, many officials believe no results or achievements in family planning can be seen in the short-term, leading to a lack of motivation on the issue.
The report also found that governments in some big cities have slacked off on the effort, because they have no trouble attracting people to live there.
