[[Child-sex effects on further births]].
This paper clarifies the child-sex effects on the number of additional children in Japan.  The data were retrospective birth histories of the 8th Japanese National Fertility Survey carried out by the Institute of Population Problems in 1982.  1st, the authors found that the majority of the Japanese had a balanced sex preference.  There was a slight shift from boy preference to girl preference in terms of the parity progression ratio.  The effect of the 1st child's sex was small, but the effect of the parity-2 sex combination was as big or bigger than that of other socioeconomic variables.  Next, the authors observed some evidence suggesting strong sex preference in opinion and behavior, such as differential intentions of further childbearing due to the sex of previous children and differences in the number of abortions caused by the sex combination of living children.  Finally, the authors noted further issues to be examined in the study of sex preference in Japan.
