In Lisbon, the waiting area of Portugal's biggest maternity hospital is empty. You can hear the hum of soda machines across the hall. There's just one expectant father, pacing the room.

Mario Carvalho, 40, has a toddler son and now awaits the birth of his baby girl.

"Today, I hope!" he says with a nervous smile.

The birth of a new baby is a joyous occasion. But in Portugal, it's an increasingly rare one. Since the economic crisis hit, the country's birthrate has dropped 14 percent, to less than 1.3 babies per woman — one of the lowest in the world.

Rising unemployment and poverty mean people are putting off having kids, or moving abroad. Portuguese schools and maternity hospitals are closing. They just don't get enough business anymore.

Carvalho says he's able to have a rare second child thanks only to his relatively secure public sector job, as a Lisbon bus driver. But his wages have been cut, and he worries about the future.

"I have a lot of friends going to England, to France — because they don't have a job in Portugal," Carvalho says. "It's difficult, very difficult."

More than 100,000 Portuguese of child-bearing age move abroad each year. That's one person emigrating every five minutes, in a country of just 10 million. Many of those who stay home in Portugal put off having families indefinitely. They can't afford it.

Lowest Level In 60 Years

Dr. Ana Campos is the head obstetrician at the hospital where Carvalho's daughter is being born, Maternidade Doutor Alfredo da Costa. She first started delivering babies here 32 years ago.

"The rooms were filled. We had more than 40 deliveries a day," Campos recalls. "And now we have 10 deliveries in one day — one-quarter."

Two whole wings of the hospital now sit unused, with the lights off. And Portugal is limiting the number of medical students admitted to study obstetrics in public universities. The country doesn't need them anymore.

Birthrates have been falling across southern Europe for decades, as women in traditionally Catholic countries like Spain, Portugal and Italy get access to birth control and higher education, and enter the job market. But Portugal has seen the biggest, fastest drop in births — down to the lowest level in 60 years.

"In fact, we have hit an all-time low, since we have records, of birthrate," says Arlindo Oliveira, who heads the Instituto Superior Técnico at Lisbon University.

Oliveira says that extremely low birthrate, combined with Portuguese emigration, creates a demographic time bomb.

"What we are looking at is a decrease in the total population — and in particular, in the working-age population, because the population is also aging," he says. "The weight of the older generations on the working-age population will be very, very high."

Fewer future workers and taxpayers are being born to pay for the rest of the population's retirement. Portugal is already bankrupt. It got a $103 billion bailout from Europe two years ago, and may need another one.

A Whole Village Celebrates

Portugal's lopsided demographics are nowhere more evident than in the fast-emptying countryside. In the country's biggest and poorest province, Alentejo, the birthrate has dropped 55 percent since 1981.

"There are only two or three children in a small village, and there are like 10 or 15 more elderly people than there used to be," says Luisa Condeço, a doula birthing coach who lives in Alentejo's biggest town, Évora. "So they're closing some schools and preschools and transforming them into nursing homes for older people."

Condeço says her clients' family planning is influenced largely by Portugal's insecure economic future.

"I listen to a lot of stories of people being scared, saying, 'Oh, we'd love to have another baby but we cannot do that. Because either one of us is unemployed, or we don't know what's going to happen,' " she says. "Especially because of that — they don't know what's going to happen."

But when a baby is born, the whole village celebrates. Rare birth announcements are splashed on the front pages of weekly papers in rural communities. Town halls deliver gift baskets to the lucky parents' doorstep. And the grandmothers, of course, are ecstatic, says Condeço.

"Especially the grandmothers — they're always complaining, 'Oh, this is the only one!' So they go and buy everything they can," she says. "I have seen that so many times. They want to do everything they can, because it's going to be the only granddaughter or grandson they have."
