China's National Bureau of Statistics said it will conduct a nationwide sample survey from Thursday to "accurately" monitor population changes and better plan economic and social policies, as authorities struggle to boost a fall in births.
The survey, which will run until Nov. 30, comes after the bureau conducted a similar poll in 2023.
Beijing is urgently trying a variety of measures to incentivize young couples to have children after China posted a second consecutive year of population decline in 2023, Reuters reported.
Rapid aging has become a growing concern for policymakers, with China's cohort of those aged 60 and older expected to rise at least 40% to more than 400 million by 2035, equal to the populations of Britain and the United States combined.
The survey will focus on urban and rural areas to "accurately and timely monitor and reflect the development and changes in population" and help formulate "national economic and social development plans," the bureau said in a statement.
Local governments and personnel will be held accountable for any "illegal acts" during survey work, and all sectors of society must "actively support and cooperate" with the survey, it said.
Population development has often been linked to the strength and "rejuvenation" of China in state media, amid the declining birth rate and widespread concerns by citizens on the difficulties of raising children.
Chinese health officials said in September that they would focus more efforts on advocating marriage and childbirth at appropriate ages and called for shared parenting responsibilities to guide young people towards "positive perspectives on marriage, childbirth and family.”
Many young Chinese are opting to remain childless due to high childcare costs, an unwillingness to marry, or put their careers on hold in a traditional society where women are still seen as the main care-givers and where gender discrimination remains rife.
The number of marriages in the first half of this year fell to its lowest level since 2013, official data showed.
China last conducted its once-in-a-decade census of the entire population in November 2020, which showed the population grew at the slowest pace since the first modern survey in the 1950s.

Bull sharks are lingering off Sydney's beaches for longer periods each year as oceans warm, researchers said Friday, predicting they may one day stay all year.

The predators are migratory, swimming north in winter when Sydney's long-term ocean temperatures dip below 19 degrees Celsius (66 degrees Fahrenheit) to bask in the balmier waters off Queensland.

A team of scientists looked at 15 years of acoustic tracking of 92 tagged migratory sharks in an area including Bondi Beach and Sydney Harbour.

Records show the sharks now spend an average of 15 days longer off Sydney's coast in summer than they did in 2009, said James Cook University researcher Nicolas Lubitz.

"If they're staying longer, it means that people and prey animals have a longer window of overlap with them."

Shark attacks are rare in ocean-loving Australia, and most serious bites are from three species: bull sharks, great whites, and tiger sharks, according to a national database.

There have been more than 1,200 shark incidents around Australia since 1791, of which over 250 resulted in death.

Researchers found an average warming of 0.57C in Bondi for the October-May period between 2006 and 2024, said the study published in the peer-reviewed journal Science of The Total Environment.

Over a longer period, remotely sensed summer sea-surface temperatures in the area rose an average 0.67C between 1982 and 2024, they said.

"If this trend persists, which it likely will, it just means that these animals are going to spend more and more time towards their seasonal distributional limit, which currently is southern and central New South Wales," Lubitz said.

"So it could be that a few decades from now, maybe bull sharks are present year-round in waters off Sydney," he added.

"While the chances of a shark bite, and shark bites in Australia in general, remain low, it just means that people have to be more aware of an increased window of bull shark presence in coastal waters off Sydney."

Climate change could also change breeding patterns, Lubitz said, with early evidence indicating juvenile sharks were appearing in rivers further south.

There was some evidence as well that summer habitats for great whites, which prefer colder waters, were decreasing in northern New South Wales and Queensland, he said.

Tagged sharks trigger an alarm when they swim within range of a network of receivers dotted around parts of the Australian coast, giving people real-time warnings on a mobile app of their presence at key locations.
