"Single is counted as being never married, divorced or widowed."
Aha. So this is ACTUALLY a map of when people first marry, and females tend to uniformly marry [and divorce] earlier, versus men who sometimes wait until later. Thank goodness, the map was really starting to worry me.
That said, I don't see why the definition of "single" makes a difference to you, unless your concern was that we're going to have a catastrophic shortage of women in 50 years. Women may simply marry earlier in life, but you're still just as screwed if you're a young guy (Or not, as the case may be.)
It's really nice to see them break down why it seems to skew so male at the younger ages, as opposed to OH NO THERE ARE NO GIRLS.
P.S.: Oh no, there are no girls! =)
