in most developed Asian countries, there are increasing concerns about low birth rate and fast ageing population. however, what is less reported but potentially societal problem is one-child family. this can be due to legal constraint or personal choice. one study published early this year examining the behaviour of "single" child in China received lots of attention in Western countries but relatively unheard of in Asian countries.
In this study, Cameron and colleagues reported that this single child is "less trusting, less trustworthy, more risk-averse, less competitive, more pessimistic, and less conscientious individuals". These are the future electorate and "leaders" of the our society. Should their parents be concerned? should the government be concerned?
