Changes in China's one child policy may not herald baby boom

Reuters Business  Report - Only child Zhang Jiayi and only child Wu Wen marry and have their only child Qiqi. A typical family in China today.

But they would love to give Qiqi a little brother or sister.

FATHER, ZHANG JIAYI, 

"For our generation in most cases both parents worked and during vacation you end up alone at home with the house key around your neck and lonely. no one to play with."

China's one child policy -- thirty years of it and now well over 200 million kids have no siblings.

And there are fewer and fewer young workers to keep the country going.

"Expectations are rising that China's new leadership will move away from the infamous one child policy. Demographers have been calling for further loosening for years now to slow down the rapid aging of the nation."

China introduced the one child policy in 1979 but has been watering it down over the years. Farmers can have a second child if the first is a girl. If both parents are only children like Zhang and Wu, they can also have two. So what happens if a two child policy kicks in?

ECONOMIST, STANDARD CHARTERED, STEPHEN GREEN, 

"Well if they eliminated it completely or went to a two child policy, I don't think there will be a huge baby boom. Maybe a mini one but it'll quickly be over I think. China is already a relatively prosperous economy, people in the cities already make a kind of level of salary, kind of level of income, where you wouldn't expect them to have five kids."

Despite more lax controls in the countryside, the one-child policy has been very effective, literally cutting the country's birthrate in half in the last 30 years

Some of that's simply because of the high cost of raising a child in China, especially in the big cities. Shanghai for example has one of the lowest birth rates in China

For our one-child couple Zhang and Wu, the decision to have a second isn't easy.

FATHER, ZHANG JIAYI, 

"Children are a big burden. You need to consider your salary and you need to see what kind of child you already have. Are they well behaved or not."

Badly behaved or not… China needs more children. But a two child policy, even if it does come, may be too late to reverse China's slide into old age.
