Our fan Aliza W. just asked us a great question: are there more girls or boys in the world? At birth, more boys are born: for every 100 baby girls, there are 106 baby boys. If you look at people of all ages, though, it evens out to about 1 boy for every girl, partly because women live longer than men. In fact, if you look only at people 65 years or older, there are only 3/4 as many men as women!

*Wee ones:* Do you have more girls than boys in your family, or more boys than girls? How many of each?

*Little kids:* If a boy swings on the monkey bars, then a girl, then a boy…does a girl or a boy go 6th? *Bonus:* If there are 7 kids on the jungle gym and there’s 1 more boy than girl, how many of each are there?

*Big kids:* If 106 boys and 100 girls line up for tug-of-war, how many kids would that be in total? *Bonus:* If 19 more boys show up, how many more girls do we need to have equal numbers of each?

*The sky’s the limit:* If 800 200-pound men do tug of war against 1,000 women, how much do the women have to weigh to match the men’s total weight?

__Answers:__

*Wee ones:* Different for everyone…count up your family!

*Little kids:* A girl goes 6^{th}. *Bonus:* 4 boys, 3 girls.

*Big kids:* 206 kids. *Bonus:* 25 girls.

*The sky’s the limit:* 160 pounds each, since the men weigh 160,000 total.
