Extract

In England and Wales in 1938–68 the sex ratio of children liveborn or stillborn to women aged 45+ years was lower than the sex ratio among children born to women at any other age. This strengthens the suggestion that the high sex ratio reported by Takahashi among children born to elderly women in Japan is a spurious consequence of false registration.
