Girls are on top yet more boys are born even in stressful times? "Over the whole period 52.4% of births were of boys. In some months, though, that fell as low as 51.2%."
I believe it doesn't even out until relatively late late in life, with male mortality being slightly higher at all ages. From the wikipedia article:
The "First World" G7 members all have a gender ratio in the range of 0.95–0.98 for the total population, of 1.05–1.07 at birth, of 1.05–1.06 for the group below 15, of 1.00–1.04 for the group aged 15–64, and of 0.70–0.75 for those over 65.
Also, some of the comments attached to it are... odd.
