Influence of combination of sexes of children on family size in an Indian population.
During 1972-74 and 1977-78 data on sex composition of children were collected in the Visakhapatnam District of Andhra Pradesh, India. Significantly more parents ceased having children when the first few children were of different sexes. Among those families with children of the same sex, there were significantly more all-male children than all-female children. Positive correlations were observed between the sexes of successive births.
