Statistical concept and methodologyMethodology: Sex ratio at birth is calculated as number of male births divided by number of female births. Statistical concept(s): If the sex ratio at birth is greater than 1, it indicates more boys born that year than girls.
Development relevanceIn the absence of interference, it is expected that the sex ratio at birth is fairly stable within the range of 1.03 to 1.07 boys born per 1.00 girls. However, in some populations, the observed sex ratio at birth is well above this range because of sex-selection driven by the preference for sons over daughters.
