​Italy's birth dearth

Just in time for Mother's Day, a new report finds the average number of children American women have in their lifetime is remaining fairly steady, at roughly two -- hardly enough to outweigh the birth dearth much of the rest of the world is experiencing. Our Cover Story is reported by Elizabeth Palmer:

The feast day of St. Efisio is a celebration of his main miracle in the 17th century, when he banished the plague from Sardinia.

It's also a glimpse of the past, when each village -- defined by its customs and its costumes -- was dominated by huge, tightly-knit families, generation after generation.

Families that were exuberant, extended -- and these days, all but extinct.

In an empty delivery room at the Villa Elena clinic, here's the new reality: the midwife, Giulia Tesio, told Palmer the number of babies she's delivered annually has dropped by 70 percent.

Babies, like tiny Reuben, are increasingly rare in Italy. In fact the, official figures show that in 2014 there were fewer babies born in Italy than at any time since 1861.

Reuben's besotted Mom is Sabrina Fenu. A social worker, she had to work full time until she was 40 to afford a home and future for her son. "Italian women now wait," she said, "until we're financially stable. Then we have just one child. We'd like to have more, but the conditions just aren't good enough."

Of course, in the old days, before birth control, conditions weren't that good, either. Women often had to bring up lots of children with little money.

But Francesca Zenoni, who helped organize the St. Efisio parade, says modern expectations have risen.

"Nowadays people don't want to raise their child in poverty," Francesca said. "They want a good level, a good standard of life for their kids."

That's true across most of the developed world. The birth rate in North America, Russia and Europe is already below the replacement rate of about two children per couple. And in Italy, a quarter of all women have no children at all.

That's partly the fault of a system that gives women no support, says professor Elizabeth Addis, an expert in demographics and social policy. More than 50 percent of Italian women work outside the home, and yet there's no affordable day care here, no school meals, and no after-school programs.

"In Italy, this virtuous process of building public services to help women, and to substitute for women's traditional work, didn't happen," Addis said.

"A lot of Italian women are trapped," said Palmer.

"Right. They will be trapped in a dependent situation in which they can only be housewives, and they don't want to be housewives -- they want to be free."

Addis' own teenage daughter, Katherine, is still living at home, but she's heading off to college soon, with plans for a career -- and a life that doesn't include children.

"There's always a dual obligation of women, both towards their family and their job," she said. "It has always been and will always be a hard balance, and I honestly don't want that."
