How serious is son preference in China?

Why are female foetuses aborted in China' Does an increase in the number of abortions of female foetuses reflect an increase in son preference' Sociologist Lisa Eklund from Lund University in Sweden has studied why families in China have a preference for sons. At the time of the census in 2005, almost 121 boys were born for every 100 girls. Last year's census showed that sex ratio at birth (SRB) had improved somewhat. But it is still too early to celebrate, in Eklund's view: the narrowing of the gap does not necessarily mean that girls are valued more highly. Because of the high SRB, there has been a tendency to picture China as a country where son preference is strong and possibly increasing since the 1980s. However, Eklund argues in her PhD thesis that using SRB as a proxy indicator for son preference is problematic. She has therefore developed a model to estimate what she calls "son compulsion", where data on SRB and total fertility rate are used to estimate the proportion of couples who wants to give birth to at least one son and who take action to achieve that goal.
