Health authorities in the southwestern province of Sichuan will allow unmarried individuals to raise a family and enjoy benefits previously reserved only for married couples, in the latest effort to bolster a falling birth rate.

The government dictates that only married women are legally allowed to give birth, but with marriage and birth rates having fallen to record lows in recent years, provincial authorities revamped a 2019 rule to cover singles who want to have children.

From February 15, married couples and any individuals who want offspring will be allowed to register with the government in the nation's fifth most populous province, with no ceiling on the number of children they can register for.

The measure aims to "promote long-term and balanced population development," Sichuan's health commission said in a statement on its website.

Until now, the commission had allowed only married couples who wanted to have up to two children to register with local authorities.

The mainland population shrank last year for the first time in six decades, a historic turn expected to usher in a period of decline. That prospect is pushing authorities to roll out incentives and measures to boost the population.

A nationwide registry system for couples to register with local authorities ensures maternity insurance to cover medical bills, while letting married women keep their salary during maternity leave.

These benefits will now be extended to single women and men in Sichuan, which ranks seventh in the nation in terms of those older than 60, or more than 21 percent of its population, government figures show. (Reuters)
